17" x 1-3/8" x 1". Waterproof LED combination trailer tail light acts as a brake, tail, and turn signal when properly mounted. Durable polycarbonate housing and lens. Surface mount - hardware not included. 3-Wire design.

by:

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.



by:

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:

Great purchase experience. 11-LED Optronics Trailer Light STL79RB was delivered as promised and fits perfectly. Recommend this item and will return for my future lighting needs.

Update: Have trailered my boat 3-4 times per month in the last year and these lights are still burning bright! Great, reliable product.



by:

Nicely done Optronics and eTrailer. Solid and simple snazzy, I need all the snazzy I can get. Great value.

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!


by:

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!

Item was delivered in good condition packing was proper. Item was as described and fit properly.

@John We're glad you had the information you needed!


by:

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.



by:

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!

Worked great, I used them on the sides of my headache rack.

There still working perfectly



by:

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.



by:

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:

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.

At first I was shipped the incorrect part but with a quick phone call with an actual person the mistake was corrected and I received the part in a timely



by:

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:

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.

Rebuilt my boat trailer, have had them underwater several times and working
Perfect. Great easy product!



by:

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!



by:

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



by:

I really like them for my teardrop trailer we are building. It was an excellent choice. Thank you



by:

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



by:

Wanted to change my back lights on my toyhauler so bought these and they look and work great



by:

Easy to hook up and work perfect very b right.



by:

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.

Same opinion as right after installed, still pleased!



by:

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.

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

  • Compatibility of Optronics Streamline LED Trailer Lights for 2018 Grand Design 220RK 5th Wheel
    You can absolutely remove the factory tail lights and replace them with a style you prefer like the Sealed, Streamline LED Trailer Stop, Turn and Tail Light, 3-Function, 11 Super Diodes # STL79RB. These are designed to be used as a replacement light and not simply an additional light, but they can be used for either purpose. I've attached a video of this installation for you to assist. There is an optional chrome base used only for the look that works with this light. It is # A79CB...

  • Operation of Optronics Streamline LED Trailer Lights STL79RB
    Yes, what you are describing is normal operation for the Optronics Streamline LED Trailer Tail Light # STL79RB. 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.

  • Tow Bar Lighting Recommendation for a 2002 Saturn S-Series
    A much easier solution that would give you a permanent flat tow lighting solution for your 2002 Saturn S Series would be to install a bulb and socket kit like part # RM-155. Basically with this kit you would install an additional bulb in the current taillight housing of your vehicle which the tow bar wiring will control. I attached an install video for this product for you to check out. Or if you really wanted to make a taillight kit with LED light bars you would want the part # STL79RB...

  • How to Make Third Brake Light Adapter for Cargo Carrier
    Since your trailer wiring will have the stop and turn signal circuits combined onto one wire you'll need a converter to isolate out the stop circuit for adding an additional brake light. For that you'd want the part # 118158 wired to your trailer wiring and the red wire would carry the circuit needed for the third brake light. You can make a wiring kit for your cargo carrier using a 4-way connector like the part # HM48133 wired to the # 118158 and mounted to your carrier and you'd have...

  • Replacement Tail Light For A 2016 Lance Travel Trailer
    We do offer a light that looks very similar # STL211XRFHB. This may not be a direct replacement but it is a very similar LED trailer light. The light itself measures overall 7-1/2" wide x 3-1/4" tall x 3/4" deep. The light face is 6-1/2" x 2-1/4". It uses a 4 wire connection. If you are able to measure the current light, we can definitely narrow down a replacement.

  • Is the Sealed Optronics Light part # STL79RB Sealed or Exposed on the Back
    The back of the Sealed, Streamline LED Trailer Stop, Turn and Tail Light # STL79RB that you referenced is sealed. I pulled one from our warehouse to confirm this. The picture is a little misleading as it looks as if its exposed on the back side, but if you look closely you can see that there is a clear seal that protects the circuit board. You can tell its there by the reflection of the light on it.

  • Trailer Brake Lights Stopped Working After Adding Additional LED Trailer Lights
    The 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....

  • Is the Streamline LED Light a 2 or 3 Bulb Light
    The item you selected, Sealed, Streamline LED, part # STL79RB, wires as a 3-wire unit. So, this would work great with your camper as brake light and turn signal function are shared on this unit. There will be three wires on part # STL79RB, a white, red, and black wire. You will need to test each wire on your camper using a circuit tester, part # PTW2993, to determine which wire function is which. The white wire is the ground wire, this will need to be ran to a clean metal surface or bolt....

  • Trailer Wiring Harness Recommendation for a 2001 Subaru Outback
    The recommended trailer wiring harness for your 2001 Subaru Outback is the part # 118461 that plugs into the port in the rear cargo area of the vehicle. The standard way to use this harness is to keep it stored in the cargo compartment of the vehicle when not in use and then run it out the back door when needed. Some people don't like the routing of the 4-way when it comes out of the back hatch of the vehicle, but it does protect the harness from weather and damage when not in use. Corrosion...

  • Availability of Red LED Light Bar for Car Hauler Trailer
    One item that may suit your needs is Optronics # MCL88RCB. This light bar is 17-inches long, uses 11 red LEDs and features a 2-wire hookup. This is a single-function light. Part # STL79RB also has similar dimensions and 11 diodes but has a red lens. This is a 3-function light. Part # STL80RB is an 11-LED, single-function red lens fixture. All light bar products are linked for your review.

  • Recommended Lights to Increase Visibility on Hitch-Mounted Bike Rack
    The Optronics Sealed, Streamline LED Trailer Light # STL79RB referenced in your question will work to provide an additional light on your bike rack, however there may be easier options. You might have trouble mounting the light assembly to the rack itself and the 3-wire design will not allow for easy disconnect when you are not using the bike rack. For an easier option, I recommend looking at the LED Light Kit # 98174LED. You can easily mount these to your bike by using the Mounting Bracket...

  • What Wiring Would be Needed to Install a Third Brake Light Mounted to a Boat Outboard Motor
    To add a third brake light to a trailer is pretty simple, but does require an adapter to convert the signal. Because trailer tail light systems combine the stop lamp and turn signals for each side onto a single circuit, you will need to use a vehicle-to-vehicle tail light converter, part # 118158 like you mentioned to split the brake light circuit back out. Looking at the diagram I produced for you will give you a good idea of the wiring layout. Now the temporary mount for the light...

  • Can Turn Signal and Brake Light of Optronics Streamline LED Trailer Tail Light Function at Same Time
    The 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.

  • Left Side LED Trailer Stop and Turn Light Not Working on a 2008 Interstate Low Pro Cycle Trailer
    Since the lights from the left side work on the right when switched and the working lights from the right are not working on the left side, the lights have been eliminated as the source of the problem, unless the ground on the left side is not sufficient. I would check the left side ground and make sure it is attached to clean metal on the trailer frame. If that does not solve the issue, start at the truck and disconnect the trailer. Then, with a circuit tester # PTW2993, make sure that...

  • How Does LED Clearance Light part # STL79RB Wire to Trailer Wiring that Uses 2 Wires
    Your 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.

  • 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.

    The Optronics LED 3-Function Trailer Light, Part # STL79RB, is intended for use on a trailer to provide stop, turn and tail light functions. It is not intended for use as a replacement tail light on a vehicle, although this sort of application is not uncommon. You might want to check with your local DOT or highway patrol just to confirm that using these and separate amber bulbs for turn signals, as you intend to do, is legal in your state.

  • How to Wire Up a Powered Winch Mounted at Rear of Truck
    I attached a help article that details exactly what is required for wiring up a winch, but for your setup you would want to go with a wiring kit like part # BDW20043. This will run wires up directly to the battery. LED lights draw a very small amount, so you could power them pretty easily off of the 12 volt accessory circuit of the 7-way which is in the 1:00 pin position.

  • Is the STL80RB Optronics Streamline LED Third Brake Trailer Light Available or What Option is There
    I 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.

You will need to make sure that adding additional lights will not overload the electrical system on the tow vehicle or the converter (if it uses one).
