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.



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.

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:

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:

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:

for the price you cant go wrong with th em



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:

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



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:

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:

perfect for my kayak trailer



by:

Great kit! Includes front marker lights, splice connectors, wire support clips. Just about everything. The only things missing would be red splice connectors for tying in the taillights. Just a suggestion, it would be great if the ground wire was a little longer, and a bigger eyelet for the ground.



by:

Have not yet installed the lights but the system is complete well built.



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:

Easy to install just follow the instruc tions.



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.



by:

EZ to install.

  • Difference Between Trailer Taillight Kits that are for Over 80 inches in Width and Under 80 inches
    There are different taillight requirements for trailers that are over 80 inches in width vs. ones that aren't over 80 inches in width. If you check out the link I attached you will see all of these differenced highlighted. The over 80 inch kits like the part # TL16RK typically come with additional clearance lights when compared to the under 80 kits like the # TL5RK. I attached review videos for both kits for you to check out.

  • Replacement Light Kit Recommendation for a 1994 Ranger Boat Trailer
    If your boat trailer is under 80" wide I recommend the Submersible, Under 80" Trailer Light Kit with 25' Wiring Harness # TL5RK but if it is over 80" wide I recommend the Optronics Trailer Light Kit for Trailers Over 80" Wide # TL16RK instead. I'm not sure what all came on your 1994 Ranger boat trailer but these light kits are a good starting point. If there are additional reflectors or lights you're needing to replace please shoot me some photos of everything you need replaced and I'd...

  • Trailer Right Rear Tail Light Only Works Sometimes
    I believe that you are experiencing a ground problem, which can cause all sorts of weirdness. There are a couple of usual suspects that you can investigate to get to the source of the problem. First, make sure that the main trailer connector ground is attached to a clean and corrosion free bare metal surface. Next you will do the same for each of the trailer lights. The lights with tail light kit # TL5RK ground through the mounting studs. Make sure those are also attached to clean metal...

  • How to the Lights in Trailer Light Kit TL5RK Ground to the Trailer
    The lights included with light kit # TL5RK ground through the mounting studs. The light grounds should also be attached to clean and corrosion free bare metal surfaces. If there is anything between a light ground and the metal trailer frame or if the trailer has an aluminum frame, tilt bed, or folding tongue, any of these things can interrupt the ground. Running jumper wires from the light grounds to the main trailer connector ground can help. It does sound like a weak ground connection....

  • 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...

    The Trailer Light Kit part # TL5RK is an excellent option for a 6 x 12 Utility Trailer and it comes with everything that you need; both tail light assemblies, the trailer wiring harness, two side marker, a plate holder, and wire connectors/hardware. It has LEDs which are both brighter and last longer than standard incandescent bulbs.

  • 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...

  • Troubleshooting Trailer Brake Lights that Work Intermittently
    Since they work then stop working most likely you have dirty pins on your trailer connectors which is causing the connection to be intermittent. Since it's both sides of the trailer it's probably the ground circuit. Your generation of Chevy truck is notorious for the third brake light fuse going out. You might check under the hood to verify if that circuit is solid still.

  • 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...

  • Troubleshooting Boat Trailer Lights That Don't Work When Vehicle Headlights Are Turned On
    It sounds like what you're describing could be an issue with the ground wire on the trailer-either a short or an insufficient connection. This is a common cause of lights working initially but then malfunctioning when another load is added to the mix. I would start with checking the ground wire on the trailer to make sure that it is firmly connected to a paint and corrosion free spot on the trailer; it would also be worth checking the ground wire on your vehicle's wiring harness at this...

  • 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...

  • How do Tail Lights in Submersible Trailer Tail Light Kit Secure to Trailer

The bracket must be attached securely to the trailer frame because the lights in this kit get their ground connection through the mounting studs. I have included an installation video and a video review of this light kit for you to check out as well.

  • Trailer Brake Lights Will Not Work and Blow Vehicle Stop Light Fuse when Trailer Is Connected
    It sounds like there is a short circuit somewhere that is causing an overload condition which is blowing the fuse and/or not allowing the lights to work properly. To locate a short on the trailer you will start by making sure the trailer connector is clean and free of corrosion inside and out. Then make sure the main ground wire is attached to a clean and corrosion free bare metal surface. Do the same for each light. Then you will need to examine the wiring from the connector back to...

  • Troubleshooting Running Light Circuit Not Working On Right Side of Trailer
    The blinker/brake lights are carried on one circuit and the running lights are on a totally different one. Since the stop/turn circuits seem to work on the left side but the running lights on that side do not you need to check the wiring of the running light circuit that runs to that side of the trailer and fix as needed. I attached a diagram of how a trailer is normally wired as well as a help article that covers troubleshooting trailer wiring as well.

  • 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.

  • Both Portable Lights Flash On Tow Vehicle When Hooked Up to RV
    It sounds like you are using magnetic lights like part # TL21RK on your towed vehicle that has a 4-pin that connects to a 7 to 4 pin connector at the RV. I recommend to check all of the wiring for frays or damaged wiring to make sure there is not a short that is allowing 2 functions to get a signal at the same time so the magnetic lights light up at the same time. What type of adapter are you using and did you use it before this started happening? It makes me think the problem is a short...

  • Can DOT Compliant Tires and Lights Be Added to Log Splitter
    As long as the spindle has dimensions that match a hub setup we carry we can definitely help you out with tires/wheels, so I'll need spindle dimensions to see if anything we have will match up. We have some light kits too like part # TL5RK that you can potentially use but you'll have to have places on your log splitter where you can mount these lights. Attached is an installation video for you to check out and get a good idea of what all this entails.

  • 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...

  • Trailer Wiring Recommendation for a Trailer Less than 80 inches Towed by a 1992 Ford Explorer
    The Optronics Trailer Light kit # TL5RK that you referenced would be an excellent choice for you and would work very well on your trailer towed by your 1992 Ford Explorer with the only exception is that the wiring is 18 gauge instead of 16 gauge like you said you preferred. I can assure you though that this wiring kit will work well for you and the amperage draw would not be too much for the wiring.

  • Trailer Right Side Running Light Does Not Work
    This sounds like a potential ground problem. 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...
