Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The circuit board is sealed, which means that water will not damage the diodes or circuit board.

I received the light earlier than expected. Was originally concerned when I opened the box as it was wrapped in a plastic bag wrapped in celephane. However once unwrapped appears to be good quality and no damage was noted. No issues with installation but as this is a replacement light, would have been nice to have directions for wiring included in the package. Otherwise, once installed it works like a champ. 898051

After I kicked the light one day at the launch ramp, breaking the lens, I was delighted to find that i could just order the necessary lens - which came with new electronics at a decent price from etrailer. Now a year later, it is all working well - whenever we manage to get to the water - and it has maintained it's waterproof status after many dunks in the salt chuck. Good product and fine service. 779661

Ordered this item to replace the exact one that was damaged (owner backed into something) while on the trailer. This is the driver side unit of the set of rear trailer LED lights ordered previously from etrailer that were a perfect replacement for a Trailex trailer model 7841 (open car trailer) incandescent taillight set. Very happy with the fit and function. Glad it was easy to order and replace the damaged unit. 769910

  • Rewiring Boat Trailer for 7-Way to Use LED Lights
    There are a number of things you will need if you want to re-wire your boat trailer to use LED lights and you should start with the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141. Keep in mind you will also need Ring Terminals # 44-5310A and Loom Clamps # A0500 The box is color coded like this: - White (ground): 10 gauge - Black (12V power): 10 gauge - Yellow (reverse/auxiliary): 14 gauge - Red (left turn and stop): 14 gauge - Green (tail and running lights):...

  • Recommended LED Trailer Lights for Boat Trailer that are Waterproof and Submersible
    For the same 6 by 3-1/2 inch size in LED, I recommend the LED Trailer Tail Light - 7 Function - Submersible - 23 Diodes - Rectangle - Red Lens - Driver # STL57RB along with passenger # STL56RB. If your trailer is over 80 inches wide, then I recommend the Wesbar LED Tail Light for Trailers Over 80" Wide - 7 Function - Submersible - Red Lens - Passenger # 271584-01 and Driver # 271585-01. These lights combinations are both submersible which means they are completely sealed and no water...

  • Is Optronics LED Trailer Tail Light # STL57RB a Single Light or a Pair
    Optronics trailer tail light # STL57RB, is a single light. This is the left hand side light and it has a built-in license plate light on the bottom. The right hand side light is # STL56RB. For a complete kit, you can use # TLL56RK. It includes both left and right side lights, a license plate bracket, a wiring harness, and installation hardware.

  • Trailer Taillight Recommendation for Replacing Light Part Number J-70
    I looked up pictures of trailer lights that are marked part number J-70 and the most similar light we carry to them is the LED part # STL57RB which measures 6-1/16" x 3-5/8". I attached a review video for this for you to check out as well.

  • Butt Connector Size to Use with Optronics LED Lights # STL57RB and # STL56RB
    The lights you mentioned of # STL57RB and # STL56RB use 16 gauge wire so for butt connectors you'd want to use the blue ones like part # DW05744-5 which are for 16-14 gauge wires.

  • Recommended Submersible Trailer Light For Karavan Boat Trailer
    We don't have a light that is 6 x 2-1/4 x 3-1/2 inches, but we do have lights that are 6 1/16 wide x 3-5/8 tall x 2-1/4 deep if the measurements were just given in a different order. Unfortunately trailer lighting companies change their lights from time to time and the dimensions often change with a newer design. I recommend you take this opportunity to upgrade your lights on your karavan boat trailer. I recommend you use the LED Trailer Tail Light - 7 Function - Submersible - 23...

  • Adding Third Brake Light to 1982 Burro Trailer
    To install a third LED brake light on your trailer, you will just need to separate out the combined turn signal/brake light circuits in order to get a dedicate brake light only function. To install a light like the Optronics LED Trailer Tail Light # STL57RB, you will need to use the Tow Ready Converter # 118158, along with two diodes # RM-690 to prevent back feeding. These are needed because trailers have a combined system, meaning they have one wire for left turn and brake lights and...

  • Installing New LED Lights on 2011 Karavan Boat Trailer
    It is true that a trailer ground wire will usually be white but there is never a guarantee that every trailer's wiring follows that convention. It is also indeed unusual for a ground wire to be fused; normally that fuse would be on the hot side of the circuit; but in fact having fuses in trailer wiring at all is rather unusual so it may be that the item you found (and thanks for the photo) is simply a connector used to extend the original wiring. If the original trailer lights were the...

  • Replacement Stop/Turn/Tail Light Option for a Karavan Boat Trailer
    I do have a recommendation for you but at this time we don't have the exact replacement lights for your Karavan trailer. We do have the submersible driver side # STL57RB and passenger side # STL56RB lights from Optronics though that measure 6-1/16" long x 3-5/8" tall x 2-1/4" deep. These feature LED lights, a light for your license plate, and carry the stop/turn/tail light functions. I have attached some photos with dimensions as well as review videos for you to check out.

  • Recommendations for Waterproof Tail Lights for a Boat Trailer
    Optronics tail lights # ST56RS and # ST57RS are submersible assemblies. This means that water can drain out of them. What I recommend are sealed lights such as # STL57RB and # STL56RB so water cannot get in at all. Sealed lights will have far less issues than regular submersible lights.

  • Smaller Trailer Stop/Turn/Tail Light Recommendation for Small Trailer
    In order for a light to safely cover all of the functions you mentioned the smallest option we are going to have is the LED Trailer Light part # STL57RB that you mentioned which measures 6-1/16" long x 3-5/8" tall x 2-1/4" deep.

  • Can Passenger Side Optronics Light Be Used on Both Sides of Trailer
    If you don't have a need for a license plate on your boat trailer then there's no reason you can't use the Optronics LED Trailer Light - Passenger Side # STL56RB (which doesn't include the license plate light) on both sides of the trailer. The license plate light is the only difference between the two assemblies. The "Over 80/Under 80" designations you see on some lights have to do with the trailer's width. A trailer that is wider than 80 inches requires additional side markers and...

  • Are Load Resistors Always Required When Installing LED Lights As Replacements To Incandescent Bulbs
    For your LED Trailer Tail Light - 7 Function - Submersible - 23 Diodes - Rectangle - Red Lens - Driver # STL57RB there is a good chance you won't need load resistors. Not all LED trailers require load resistors like the Putco LED Light Bulb Load-Resistor Kit - Aluminum # P230004A. It really has to do with the vehicle's wiring as much as the trailer. If you have a hyperflashing issue once you install these lights, I have a couple suggestions. If you have a 7-way trailer connection, then...

  • Do LED Trailer Lights Work with 2004 Chevy Silverado 1500 Tow Package Wiring
    I have not heard of there being any issues with using trailer LED lights with a 2004 Chevy Silverado. It is an issue on some German vehicles and theoretically could be an issue on any vehicle. But as far as specifically hearing about issues with your generation Chevy truck I have not heard anything. Most LED light problems are a result of the LED lights drawing so little power that the tow vehicle doesn't recognize them. The fix for this is to install load resistors, such as # P230004A,...

  • Options to Convert Trailer to LED Lighting
    You may be able to upgrade your trailer lighting to LEDs without having to replace the entire light assemblies.

You can see all such LED bulb replacements by viewing the page I linked for you. These LEDs are made in many colors and in lots of sizes as direct replacements for many of the most popular incandescent bulbs. If you scroll down...

  • Why Isnt There a Replacement Lens for the Optronics Taillight STL57RB
    I spoke with my contact at Optronics and they do not sell replacement lenses for these lights. These lights are submersible so they are sealed from the factory. There is no way to replace the lens and re-seal it. You will need to replace the Optronics Trailer Light # STL56RB, if you also need the left hand side you will need a Optronics Trailer Light # STL57RB.

There is also a complete Trailer Light Kit for Trailers Over 80" Wide, # TLL16RK.

  • Replacement LED Taillight Recommendation for 2002 Shoreland'r Profile 2000 Boat Trailer
    We do indeed have some LED taillights that'd work great on your boat trailer. I'd recommend # STL57RB for the driver side and # STL56RB for the passenger side. These lamps measure 6-1/16 x 2-5/8 inches, and would work well on your trailer. As you can see in the photo provided by one of our customers, the taillight works well on a Shoreland'r trailer. As long as they're still working okay, you certainly may leave the existing fender running lights in place. If you decide you want to...

They are 6 by 4 inches, LED, waterproof, mount on studs on 2 inch centers, and you would need pigtail # 40-00-003 (one for each light). LED tail light # STL56RB for the right hand side and # STL57RB for the left are a close match. They are 6-1/16 inches across and 3-5/8 inches tall. They mount on studs on 2 inch centers. The lights are submersible and the LED board sealed to keep out water.
