This is my second pair that I have purchased and both sets 1@1year ago the other more like 5 years ago are still like new and going strong. Let’s all say durable! And yes I would recommend to family and friends and random strangers alike. Let’s see here, reviews like “Stars”, 5 stars x 2 sets = 10 Stars, can I do that?

@Timothy You can do that, thank you!

Brake light has rubs and scratches on both bottom and top sides.
Disappointed in packaging, a thin clear plastic sheath inside a thin plastic mailing envelope. No protection at all during shipping.
by: Michael04/08/2024
I found that the travel trailer OEM tail lights were blocked by the cargo carrier. I installed these light as an extension of the OEM tail light. These lights enhanced the OEM lights. Now I worry a bit less about the vehicles behind me.

The LED taillights worked out great with my trailer rebuild. They will be protected at all times because I was able to have them tucked out of harms way. They are not low where backing up would endanger them and not protruding from the sides to be in the way either.
But they are still highly visible at all times from the side or rear. THANKS for a great product!

The tail lights were a great finishing touch to the rebuild of my utility trailer. The taillights are so visible and stay out of the way. They dont have those tender filaments in the old bulbs that a bouncing trailers play havoc with. Not to mention rusty bulb sockets that made the bulbs dimmer!

The clear LED tailight strips that came with my trailer started filling with moisture and were only partially working. Most trailer part places only had the 15" lights. You were the only ones I found with the 17" lights and a diagram showing the mounting hole centers and dimensions. The product pictures were great for checking the wiring. Quick shipping and the tracking link was great. A few simple tools & some butt connectors and I was done. Finished the job with clear caulking around the lights.I like the red strip over the clear stock one and the lights are easy to see even in full sun.

Looked at several lights on amazon. Flat on the back makes for a difficult connection. Found these on etrailer and worked great. Their is a good space behind the light to deal with the ground and wires. Excellent buy! Very happy with purchase. Shipping was fast and great follow up on purchase. Will buy again!

I like a lot of folks did my research, I have a specific requirement for this cargo carrier, I need it to hold a dock box made by lifetime. And this carrier works perfectly. It was very easy to assemble. And very sturdy. I enclosed a picture of the dock box installed. I had to do some modifications to the dock box, but it worked out beautifully. I highly recommend this cargo carrier for the price quality and value.

I installed this light as a third brake light at the top of my camper. LEDs, no maintenance, works great. A big improvement in safety. Order service was prompt and accurate. Good job.

by: Offroad Racer 12/16/2016
I used this as a brake light and it has handled offroad abuse and has continued to work without any segments burning out. It was wired to provide the brightest output.

These were to replace some on the back of my motorhome that I installed about 4 years ago. They corroded with Michigan’s winters and salted roads but looked so good I replaced them with fresh ones.
by: Josh H04/11/2014
Replaced the crappy original stick-out basic lights with these LED ones under the lip of the deck. Fit great, work great. Good product, as expected from etrailer.
by: Brenda 08/28/2023
I really like them for my teardrop trailer we are building. It was an excellent choice. Thank you

We installed two lights on a ramp for the rear of our car. They were so simple to install and they are very bright. Great product!

The led lights were very easy to install and they look great. Thanks

Beautifully designed, looks like two light bar, very bright and effective. I recommend this product.

Paid for 2 day shipping. It ended up taking about as long as normal ground shipping. This was my first purchase through etrailer. I will stick to RealTruck going forward
by: dave g12/26/2016
Not real happy at this point. Spent most of the day filing down the back, ( center) of the light for mounting on a flat surface. Both rails on the back of the light created a bow when screwed onto a flat surface. If I would have just attached it to the flat surface, it would have put the circuit board in a bind and I didn't think that would be a good idea knowing the beating they would take if mounted them like that on the back of my flatbed trailer. With one end screwed down, the other end was approximately 1/8 of an inch raised above the mounting rail. If mounted like that, they would not have lasted 3 weeks before cracking the circuit board. as received, the small rails on the back did not provide a flat surface for mounting. But they did when I got done filing them. If anybody is going to screw an object 17" long onto a flat surface, ( unless it is made out of rubber) it better be flat also. On top of that, the wires could stand to be a bit longer.

lights working great. I could not have made a better decision on what and who in order to obtain my desired results.
by: Bruce Ross03/22/2017
ordered for use on trailer with rear ramp that when closed (verticle) stands approx. 6'. Lights on the trailer are low to ground approx. 1'- 18". My concern was visibility of trailer brakes. Your item was flat backed long and narrow ideal for mounting at top part of trailer ramp mentioned earlier. Much more visible approx 5' high and of course led lights, much brighter. Feel more secure towing with addition of your item. Easy to install, quality, and price reasonable.

See what our Experts say about this Optronics Trailer Lights
- Replacement Strip Style Trailer Tail LightI believe I have what you are looking for. The Optronics Streamline LED Trailer Tail Light # STL79RB is most likely going to be the replacement you are wanting. Looking at your picture and comparing it to the # STL79RB I believe they are the same light. I think the "OPT-8TL 79R8" you are seeing may actually be STL 79RB and the OPT just meaning the manufacturer (Optronics). It can be hard to clearly make out what is said on the inside of the lights. The # STL79RB is 17" long but measures...

- Is Optronics Streamline LED Trailer Tail Light # STL79RB Sold Individually or In PairsThe Optronics Streamline LED Trailer Tail Light # STL79RB that you referenced is sold individually.
view full answer... - Can Turn Signal and Brake Light of Optronics Streamline LED Trailer Tail Light Function at Same TimeThe brake light and stoplight function of the Optronics Streamline LED Trailer Tail Light part # STL79RB will both work at same time without overriding each other. The two circuits are on same wire but when the blinker is on and the brakes it will just blink as that's what trailer wiring is designed to do.
view full answer... - How Does the Optronics Trailer Light # STL79RB Wire to Trailer WiringThe wiring of the Optronics Trailer Light # STL79RB that you listed are: The white wire, with the mounting eye, is a ground wire that needs to be connected to the white wire of your trailer wiring. The black wire would be connected to your running lights and is the lower intensity illumination. This should be run to the brown wire of your trailer wiring as this is usually the tail light circuit. The red will be wired to the brake/turn wire and is for the higher intensity illumination....
view full answer... - Does the Optronics Sealed Streamline LED Trailer Tail Light Include Mounting HardwareThere is no glue strip or self-adhesive tape on the backside of the light, nor are they any nuts, bolts or screws included. The light mounts via two holes on the ends of the light fixture. The holes measure 16-1/8 inches apart, center to center.
view full answer... - Troubleshooting Trailer Taillight that All Functions Arent WorkingIf the light you have on your trailer is working for some of the trailer light function it may not be the lights fault. It may be that the wiring of your trailer is causing the problem. This would be especially true if you can get both a high and low illumination from the light currently. I would recommend you apply 12 volts to all of the wires of the light (except the ground), so that you can determine if the problem is the light or the wiring. If the light behaves correctly with this...

The lamps can indeed be mounted horizontally. If you are asking as to whether the lamp could be mounted in the center of the rear of a trailer and perform the right turn, left turn, brake and running light function, the lamp is not wired to operate that way. Lamps that install between the bottom of the tailgate and the...
view full answer... - Diameter of Mounting Holes on Optronics Streamline LED Trailer Tail LightThe mounting holes on the # STL79RB are 3/32" or 2.38mm in diameter. You can use a #6 screw or any other hardware that fits to mount the lights on your trailer.
view full answer... - Troubleshooting Trailer Lights that Turn and Brake Doesn't Work When Truck Running Lights are OnWhat you're describing is typically a ground issue. But you've checked the grounds so it must be a short. You might try cleaning each ground connection just to be sure if you haven't already. Next I would clean both connectors on the tow vehicle and trailer. Also use a circuit tester on the vehicle's connector to make sure the issue is definitely on the trailer. If the problem is on the trailer trace the wiring back to the lights looking for any damaged or pinched wires. If the problem...

view full answer... - Trailer Brake Lights Stopped Working After Adding Additional LED Trailer LightsThe brake lights on the trailer draw more power than the running lights or turn signals so the problem could be that the extra lights are creating too much draw on the system which is not allowing them to work. You may need to use a powered converter that draws power for the trailer lights directly from the tow vehicle battery instead of through the vehicle wiring system. There are several available depending on the year, make, and model of your vehicle. There could also be a ground problem....
view full answer... - Installation Of The Optronics Tail Lights # STL79RBThere is not a base plate for the Optronics Trailer Lights # STL79RB. It is a sealed light, with a clear plastic backing which isn't easy to see from the pictures, but there is not a need for a mounting base plate because the mounting holed are integrated and the unit itself is sealed and thus has a waterproof housing and lens unit. You will be able to mount this light to any flat surface. The mounting holes are 16-1/8 inch center to center. You can mount these reusing the manufacturer's...
view full answer... - Are All LED's of the Optronics Stop, Turn and Taillight # STL79RB The Same BrightnessAccording to my Optronics representative, the # STL79RB is purposely designed so that the middle three diodes which illuminate the running light function are a bit more dim. The outer diodes are brighter, and the lens tends to magnify the diodes making them appear much brighter.
view full answer... - Is the STL80RB Optronics Streamline LED Third Brake Trailer Light Available or What Option is ThereI have another option for you, but the STL80RB is no longer available. We do however, have the Optronics Streamline LED Trailer Tail Light # STL79RB which has all of the same measurements as the STL80RB. The difference is that the # STL79RB is a 3-wire design that allows it to be used as a brake, tail, and turn signal. While the STL80RB is a 2-wire design that only operates as a third brake light.
view full answer... - How Does LED Clearance Light part # STL79RB Wire to Trailer Wiring that Uses 2 WiresYour current taillights are grounding through the mounting hardware which is why there's on two wires and the LED Clearance light part # STL79RB instead grounds with the included white wire. So what you'd need to do is run the white wire to the mounting hardware of your trailer frame and you'd be set. Or you can run the white wire back to the ground circuit of the trailer's wiring.
view full answer... - Troubleshooting Boat Trailer Left Side Taillight Not FunctioningIt really sounds like the problem is the ground of the left side light assembly. A lot of assemblies ground through their mounting hardware so be sure that the assembly is connected to a clean metal surface. Running a jumper wire from the mounting post of the assembly to the main ground of the trailer may help as well. I attached a help article on trailer wiring for you to check out as well.
view full answer... - LED Strip Recommendation for a Trailer for Additional Stop/Turn/Tail Function VisibilityIf your LED strips only have a power and ground wire then they only have one illumination intensity and would not work for what you are trying to do. I would un-install them and go back to the wiring setup you had previous for now. Your best option would be to get the 3-Function LED Bar part # STL79RB that you referenced as this is specifically designed for what you are trying to do. I would run one on either side of your trailer. Connect the white wire to ground, the red wire will connect...
view full answer... - How to Use Optronics Trailer Light # STL79RB so that it would put Brakes/Blinkers for Cargo CarrierOn the Optronics Trailer Lights # STL79RB you connect the black wire on the light to the running light circuit on the trailer, typically brown. Most trailers are wired with the brake and turn signals on the same circuit for each side, typically yellow on driver and green on passenger. You could hook one of these up to the red wire on the LED strip light, but that means that the light will also flash with the turn signal on that side. One option is run two of these lights on your cargo...
view full answer... - When Installing Optronics Streamline Stop/Turn Light # STL79RB Which Blinker Circuit Should be UsedIdeally you use two of the Sealed, Streamline LED Trailer Stop, Turn and Tail Lights # STL79RB. One for each side of the trailer. They can be installed right next to each other. Like this you'd be able to use the appropriate blinker circuit for the side of the trailer that way they will act as a turn signal and brake light and will flash and illuminate as needed.
view full answer... - Installation Instructions for Optronics 3 Function Streamline LED Light part # STL79RBThe white wire, with the mounting eye, is a ground wire that needs to be connected to a metal surface on the trailer that is electrically grounded like the frame. The other two wires will provide the brake/turn and running lights. This light will not provide functions for both sides of the trailer, in order to do that, you would need two units. The black wire would be connected to your running lights, and the red will be wired to the brake/turn wire. In order for this light to simultaneously...
view full answer... - Is Optronics Streamline LED Trailer Tail Light # STL79RB Sold in Pairs or IndividuallyThe Optronics Streamline LED Trailer Tail Light # STL79RB is sold individually. If you needed more than one you'd need to order a quantity of two.

When just the running lights are on the 4 diodes on top and bottom are brighter than the 3 middle diodes. When you press the brakes or use your turn signal all of them are supposed to light up. You can see this in the attached photo and review video.

- Troubleshooting Tail Light Issues on New Grand Design Trailer Since you tested the tow vehicle's connector and know it's working properly, we can at least focus all our attention on the trailer side. It sounds like you've already done this, but it certainly sounds like there's some kind of ground issue on the Grand Design that's causing the dim lights, and now the issue on the left side tail light. Check once more to make sure all your ground connections, both the main harness ground for the 7-Way and each individual ground for the light assemblies...
