Really cheap.

These lights are marketed
as submersible, but based on what's in the package I'm really dubious.

The lens bodies are not sealed. As you can see My photo, each lens body has a clearance hole for the wire - No gasket, and plenty of room around the wire, So water will definitely flood in and submerge the contacts and bulb/socket If you put these on a boat trailer.

Additionally, to Make the wire connections. They give you wire nuts. For submersible wire connections, at the very least, you should use crimp butts wrapped in tape - or better yet a heat shrink crimp butt. But they give you wire nuts, which aren't even really stable against vibration, let alone moisture.

It does say 3-year warranty on the package, however, so I guess I'll be testing that out.

Rewired my 8x4 bed trailer, and chose these fo mo betta rain proof. EZ wiring, they're working fine!

Ok, had an issue with the bulb socket for brake and turn signal. Those socket designs date back to the stone age. Hard to set the bulb for proper electrical contact. Badly needs an updated design.



by:

Great replacement light kit.



by:

generally happy with product but it was missing a nut for attaching light to trailer.



by:

Put these on an old boat trailer. Came out great. I got some white 16 gage stranded wire to carry the ground out to each mounting place. Helps the lights stay on even when stuff gets rusty.

No problems



by:

This is an excellent product and simple to install. As long as you have a functioning plug-in on your vehicle you’ll be happy.
Time will tell how well it holds up to water and vibration

I’ve since pulled my boat to the lake with the trailer that I installed this lighting harness on. I unplug the lights before I back down the boat ramp to assure I don’t short out the system. Other than that I am still satisfied and would recommend these to anyone. Simple to install



by:

The light kit works great now; however, after much sweat & experimenting. Initially, I couldn’t get any of the lights to work, then I sanded away the paint where the lights attached to get good grounds from each light bolt/screw. At that point, 1 light worked perfect while the rest remained very dim. After changing wires & tow vehicles to verify it wasn’t something wrong with that connection, I found an etrailer post about running separate ground wires from each light directly to the ground connection coming from the tow vehicle. After another run to Lowe’s & several more feet of wire - it worked. Finally!! I don’t deal with this stuff regularly so this was like looking for an electric needle in a haystack. During this process, I called etrailer & they were good enough to get ready to send me a replacement light set, thinking this one was defective. Fortunately, I didn’t need it.



by:

This is a pretty standard trailer light package. The price was good and the equipment works great. I would recommend this product. It comes with electrical clips that are garbage though so I would recommend doing something different for you connection health. Overall, I have saved it for the next time my tire explodes going down the road and takes out my lights just for added injury to my night. (lol)



by:

It is good product and I would recommend it completely.



by:

So far these have held up well. Been a year



by:

looks great just got to find time to put them in-thanx-steveb



by:

Easy to install, did mine in a storage unit with minimal tools and no lights. Great product.



by:

Price was less than the local stores and shipping was fast. The lights look well made but I haven't had a chance to install them yet.



by:

Easy installation, works the way it sho uld.



by:

Thanks ETrailer for making my boat trailer restoration a success . I restored a 1960 boat trailer to look brand new with your help.



by:

The lighting system performed well in traveling from NY to northern Michigan and return to carry an old boat back for restoration.



by:

for the price you cant go wrong with th em



by:

I was looking for something cost efficient and good quality and I found it. I put the lights on a 62 Willys pick up I'm renovating. Work perfectly !



by:

The quality of these are better than the factory lights that came on the trailer originally. They're even brighter even though they use the same kind of bulbs as the original factory lights. The price was reasonable too.



by:

perfect for my kayak trailer



by:

Work great and good price



by:

I had to replace the lights on my utility trailer. The Kit came complete with easy to follow directions. Everything matched up perfectly almost plug and play. It took about 3 hours to remove the old lights and install the new ones. The only extra thing I had to purchase was extra white ground wire. The length that came with the kit was a little short. All other wire was more than ample length. That is why it got 4 stars other than that minor thing it would have gotten 5 stars. I am not a big user but the people at e-trailer are professionals with great follow up. This is the 2nd time that I used them and I do not hesitate to recommend the company and people.

They are holding up fine and I would recommend them to anyone



by:

Easy to install just follow the instruc tions.



by:

So overall I would recommend these! The product seems a little bit like "you get what you pay for." They don't seem to be of the highest quality but for the price, getting submersible trailer lights that are down and dirty and work, they seem great.
They are on my 4X8 utility trailer and they were easy to wire and install. They do come with wire nuts to make the wire connections and I replaced them with inline waterproof wire connectors but the wire nuts would have worked just fine. Again, overall, the kit had everything you would need to make these lights work.

Thank you for your review. It sounds like you have a classic ground issue. These particular lights ground through the mounting studs so make sure they are attached to a clean bare metal surface.



by:

Ordered this light kit from etrailer and paid a little more than buying a generic set from [online retailer] thinking, like other products I have purchased here, the lights would be a better quality. Instead they arrived with very light wire, appears to be 18 gauge and average quality "submersible" lights. The cheaper lights on [online retailer] came with 16 gauge wire and looked at least if not more waterproof.

I confirmed with Optronics that the pigtail wires on the lights in this kit have 20 gauge wire. These lights are designed to be submersible and feature a drain hole on the bottom too allow any water to escape, they are not waterproof.

  • All Trailer Lights Blink When Truck Headlights and Turn Signals are Turned On
    The wiring harness on the trailer side is what is called a wishbone harness. It splits the running light signal so that you do not have to run a jumper wire from one side to the other. The yellow/brown wire is for the left side running lights and the green/brown is for the right side running lights. That could be what the problem is if you wired it differently. Make sure that the trailer lights are grounded to a clean and corrosion free location of the trailer frame. Also check to make...

  • Recommended Trailer Tail Light Wiring Kit for Trailer Under 80" Wide
    The Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness part # TL5RK is my recommendation for a trailer wiring tail light kit for trailers under 80" wide. It comes with taillights, wiring harness, license plate holder, and amber side marker lights.

  • What Maintenance Is Needed After Submersing Optronics Trailer Light # TL5RK in Salt Water
    The Optronics Submersible Trailer Light Kit # TL5RK is designed to withstand immersion in water, including salt water. So unless one of the tail or marker light units were damaged (which could allow water to enter the light housing) the only regular maintenance step that might be advisable is a thorough rinse with fresh water to remove salt build up, just as you would for your boat. Also, these units use a mounting post that also serves as a ground connection. As a periodic precautionary...

  • Replacing Taillights on a 1986 Bayliner 1650 Using Trailer Light Kit TL5RK
    Our lighting kits are not necessarily trailer specific. If the Submersible Trailer Tail Light Kit # TL5RK fits the electrical connection on your tow vehicle (in this case the light kit has 4 flat wiring) then the lights can be mounted in the existing trailer mounts if they are the correct size. The light kit has mounting studs, nuts included, that are 2 inches on center for mounting to a metal mounting bracket. The bracket must be attached securely to the trailer frame because the lights...

  • Trailer Lights Not Lighting Up Properly on Harbor Freight Trailer
    It sounds like the wiring harness you have is what is called a wishbone harness. These will have 2 wires that connect to the single running light pin, so you don't have to run a jumper wire from one side of the trailer to the other. It also sounds like you have everything hooked up correctly. Yellow is usually left turn and brake lights, green is usually right turn and brake lights, brown is usually running lights, and white is the ground. You can test this by connecting the trailer to...

  • Brake Lights Turn Off when I Step On the Brakes After Wiring New Trailer Lights
    Yes, it seems like you have a ground problem on the trailer. I would start by checking the ground wire at the trailer coupler and making sure it is connected to a solid clean paint free spot on the coupler of frame. Then I would check the tail light assemblies. Tail lights are usually grounded through their connection to the trailer frame. If you have a plastic license plate bracket on the left side this could be the culprit. You should also check the brackets that hold the lights. If...

  • Running Lights Not Working on Trailer After Installation of Optronics Trailer Light Kit # TL5RK
    There are many possible reasons why the running lights are not working on your trailer when using the Optronics Trailer Light Kit, part # TL5RK. First, I recommend checking the ground connections. The trailer lights on this kit will ground through the mounting studs. They will need to be attached to a clean and corrosion free bare metal surface. You will also want to make sure that the main ground from the trailer connector is attached to a clean and corrosion free bare metal surface....

  • Hardwiring in a Trailer Brake Controller on a Ford Expedition
    Since you are hardwiring in a brake controller you can start with the white and black wires. The white wire is ground and needs to go to the negative battery terminal. Black is power and it needs to go to the positive battery terminal via a 30-amp circuit breaker. For this you can use wire # 12-2-1, sold by the foot. There are 2 wires inside and you can use 1 for ground and one for power. For a 30-amp circuit breaker use # PK54530. The wires will need to be run through the firewall. This...

  • Will Optronics Trailer Taillight Kit part # TL5RK Wiring Last Longer Than Two Years
    That is really unusual for the wiring to basically just destroy itself within two years, but sorry to hear that. The kits we offer like the Submersible, Under 80" Trailer Light Kit # TL5RK that you referenced would not have this issue and would work really great long term. We have sold more of these kits than we can count and have not ever heard of that issue.

  • Best 4.80-12 Trailer Tires For Highway Speed
    Okay, let's go ahead and start with the best 4.80-12 trailer tires for highway speeds, and for that you want a radial tire because they run cooler and flex more than bias tires. The best option for this is a tire from Taskmaster: - Taskmaster 4.80R12 Radial Trailer Tire # TT48012C The # TT48012C has an 81 mph speed rating, the highest for this size tire, and is a load range C tire that has a 990 lb per-tire rating (so 1,980 lbs for two tires).

  • Running Light Fuse Blowing with Trailer Connecter to 2003 GMC Sierra and Tail Light Kit # TL5RK
    It sounds like there is a short that is causing an overload situation that is in turn causing the fuse to blow. The problem could be in a number of places, but I would start by checking the grounds on the trailer and on the truck. The ground for the trailer side plug should be attached to a clean, corrosion and paint free bare metal surface on the trailer frame. The lights ground through the mounting studs. They, too should be free of corrosion, dirt, and attached to a bare metal surface. If...

  • Instructions for Wiring Additional License Plate Light With Submersible Trailer Light Kit # TL5RK
    When it comes to adding an additional license plate light to the Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness, # TL5RK, I recommend taking a look at the LED Mini Trailer License Plate Light, # LPL31CB. The light has a weathertight seal to protect it against the elements and the two-wire design includes the lead and ground wires to mount to any surface. In order to wire this light, one of the wires will need to connected/spliced into the running light circuit (brown...

  • Type of Wiring Harness that Comes with the Optronics Submersible Trailer Light Kit # TL5RK
    The wiring harness that comes with the Optronics Submersible Trailer Light Kit, # TL5RK, is a wishbone wiring harness meaning there are 5 wires coming out of the back of the 4-pole flat connector. You will have one white wire for the ground, one yellow wire for the left turn and brake signals, one green wire for the right turn and brake signals and two brown wires for the tail lights. The reason there are two brown wires for the tail lights is to make it easier for you to run the wires...

  • Recommendation For LED Camper and Flatbed Tail Lights for a 2010 Ford Ranger
    I would recommend the Sealed, 6-1/2 inch Oval LED Trailer Stop, Turn and Tail Light, 10 Super Diode, item # STL72RB, for both the truck bed and the trailer. To mount these lights you will need a Trailer Light Mounting Bracket for 6-1/2 inch Oval Trailer Lights, item # BK70BB, and a Rubber Grommet, item # A70GB. To wire the lights you will need either the straight Pigtail, item # A45PB, or a the right angle Pigtail, item # A47PB. I have used these lights on a car hauler and they work excellent...

  • Will Trailer Light Kit Work With Wiring Harness on 2014 Mitsubishi Outlander
    That is an excellent question and the answer is that your 2014 Mitsubishi Outlander will need to use the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56189 with the Submersible, Under 80" Trailer Light Kit # TL5RK due to the amperage draw you referenced. The Curt kit has a max amperage of 3 amps per circuit, which will be needed for the 2.5 amps of the trailer light kit; the T-One Vehicle Wiring Harness # 118482 has a 2.1 amp capacity, as you noted, and...

Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

  • Is There Difference Between Optronics Taillight Kits TL5RK and TL29BK
    The Optronics kits part # TL5RK and # TL29BK are both very similar. Only real difference is there is a slight housing design difference between the two main taillight assemblies with the # TL29BK having the more recent design. Both are great kits that will hold up really well, better than what came on your Harbor Freight trailer for sure.

  • Trailer Turn Signals and Brake Lights Not Fully Functional Connected to 2004 Chevy Silverado
    Since the trailer lights work fine on a different vehicle, the likely issue is on the truck. Most likely there is a dirty or corroded trailer connector causing the issue but I would still not rule out a ground problem on the trailer. On the vehicle, start by making sure the connector is clean and free of corrosion. Also check where the wires attach in the back if it is a 4 and 7-Way or if using an adapter. If you are using an adapter it could be at fault as well. After cleaning up the...

  • Wire Gauge of 25 Foot Harness Included with Submersible, Under 80 Inch Tail Light Kit
    Optronics uses small 20 gauge wiring for their 4-Way wiring harnesses so it would be even smaller than 18. In order to get 14 gauge wires I recommend # DW04923-1 which is sold by the foot. Each of the wires in it are 14 gauge. Then you would just need the lights, # ST6RB and # ST7RB, 2 of # MC36AB, and license plate bracket # LP10SB. And for the additional clips, connectors, ties and other parts I recommend the wiring kit # HM51020.

  • No Running Lights, and No Brake and Turn Signal on Right Side of Trailer
    Sounds like the main trailer ground could be bad, or the grounds at each tail light could be bad. You may want to try to relocate the grounds or run all of the light grounds back to the main trailer ground. Next you may want to check the tow package fuses in the power distribution box under the hood of your truck. If the fuses are blown there has been a short and you should check the trailer wiring out before reconnecting the truck to the trailer. If the fuses check out use a circuit...

  • Can Trailer Tail Light Kits with a 4-Way Connector be Used on a Trailer with a 6-Way Connector
    You can use a trailer wiring kit like # TL5RK but to connect it to the trailer side 6-Way you would need to cut off the 4-Way end and attach the wires to 6-Way connector. The wiring color/functions on this wiring kit are white is ground, brown is tail lights, yellow is left turn and brake, green is right turn and brake. Just connect the wires to your 6-Way by function and you will be set.
