Identical replacement of broken tail light. Excellent delivery time. Ordered 4/25/23 after 7:00pm and received 4/29/23 after 11:00am, using standard delivery. Already installed and ready to travel. Thanks e-trailer.

Excellent



by:

Great replacement for the original incandescent tail light on my 1997 Shorelander boat trailer. Same hole pattern, so no drilling.



by:

Perfect, light matches exactly. Very satisfied with all my purchases: Hitch, aluminum truck rack, boat trailer lights, wiring harnesses…



by:

It is what I ordered and it fits the trailer well and no problem to install. I also like the amount of light and the brightness.

James

Great-The lights fit my trailer like the factory lights so I like that as every thing on my 1988 SeaRay boat, motor, and trailer is original except some motor parts replacements with manufacturers parts.

@James We're glad to hear that your # STL57RB trailer taillights are working well for you!


by:

The LED lamp assembly works very well and is water proof. However I put these on my boat trailer about 4 years ago and both sides have a problem that the LED assembly fell out of the housing. There is only 1 little screw holding the LED assembly in the lens. I also lost the housing on one side of the boat trailer. I had to drill holes in the lens and back plate and add tie-wraps to hold the LED assembly in place. This needs to be improved upon.
In the pictures you will notice that I added tie-wraps to the new light.



by:

WOOOOOOOWWWWWWW!!!! These lights are BY FAR the brightest I have ever seen! Even with only the tailights on, they are STUNNINGLY INTENSE! Can't go wrong getting them, easy to install, solidly (REAL SOLID) built, look like they are very durable too. Absolutely and totally impressed and well worth the money. Put other LED and incandescent lights to shame!! JUST BUY THEM, YOU WILL BE BLOWN AWAY HAPPY!!



by:

Replaced the jet ski trailer light perfectly! Lighting is much brighter than the stock incandescent bulb in all modes and light disbursement is very good, even from the sides. The license plate light comes on with the parking lights and is over-kill in lighting up the area below (that is NOT a complaint)!

Toby

As per my other review, love these super-bright lights!



by:

the light is a great replacement light for any trailer. typical of all trailer break lights the red clear lens is fragile and cracks easy.



by:

I want to thank you for all your help with my trailer you were more helpful than you realize. So this is my trailer for a 22' Flats Cat shallow draft Catamaran. I totally dismantled my trailer and buffed by hand with a wire buffer and sand blasted in some spots and applied multiple coats of some very expensive galvanize paint (Z.R.C.). I installed all new C. E. Smith Carpet (about 80'), seven new LED waterproof lights, new springs, new equalizers, new tongue jack, new wench, new safety chain, new chain brackets, all new SS hardware and a 35' long wiring harness.
I was able to send only one review with a picture of the safety chain and brackets. I'm having a little trouble with the rest..oh some of these items were bought locally or from your competitors, until I found ETRAILER. Your prices were cheaper for the exact same things. Your helpful how to videos were helpful. And Rose, your personal helpful knowledge made my buying experience very pleasant, I actually enjoyed talking to you! Thanks to ETRAILER and specifically to Rose G.



by:

very good lights. installed easily.

Lights worked perfect for my trailer as I did a lot of research and this was the only place that had trailer lights that would work with this trailer.

Still working great. No problems at all. Nice to back into the lake and not worry the lights are burnt out..



by:

I have been more than pleased with the quality and performance of the Optronics brand lights! These are no exception!

This tail light assembly is a direct replacement on my ShoreLander trailer. The running lights, including four on the side, are a nice feature. The brake/signal light are more intense as expected. Lastly, the dimensions and mounting holes allowed me to bolt them into place without issue!

I, like others, am amazed at the brightness of the lights. They are a huge upgrade over my existing incandescent lamps! I am looking forward to no more burnt/broken bulbs!

I have purchased Optronics tailslights in the past, and am purchasing again as I like the quality/performance of the taillight assemblies. I would buy again and I would recommend to others as well!



by:

Just installed new lights. I think these are a nice, very bright LED light but they shipped without any mounting hardware. I would excpect that for the price it would of come with the licence plate holder and at the very least mounting screws and nuts. It added an extra hour and several more bucks to this project to hunt them down at the Home Depot. I will see in time how the lights hold up in salt water



by:

Works great and mounts perfectly in place of original incandescent light.



by:

I ordered this lamp because I am thinking LEDs will not be affected by the submerged in water. I had incandescent lamps that burst when submerged because the housing was not watertight



by:

Exactly what describe, super fast shipping. Worked well on my shorlandr boat trailer.
Only 4 stars because I haven't submerged the lights yet!



by:

Exactly what I needed



by:

Quality LED lights. Easy to install and one year later they are still working well.



by:

just what I wanted, fits my 2007 Karavan boat trailer and I love the upgrade to LED. thanks



by:

Very quick and easy Installation.
I
would recommend this product to anyone



by:

I ordered these LED Trailer tail lights (STL57RB and STL56RB) for my 1988 Shorelander trailer. I was having a hard time matching the dimensions of my worn out lights. These new lights fit perfectly. They were easy to install, but if you have questions the etrailer.com web site has resources including videos that can assist you. LED is the way to go. These lights are much brighter than the old incandescent model.

Dave D.

The trailer lights are working great. Im very satisfied with the product and your company



by:

Bought these to retrofit my 2004 Shoreland'r boat trailer. etrailer's price was very competitive, they shipped exactly when they promised and the lights arrived quickly thereafter. The website description was accurate and provided exact dimensions so lights fit just as expected. Installation was fast and easy with the fasteners provided. I had heard rumors about LEDs not working properly with some 2004 GM electrical systems but there was no problem with these. Very satisfied with the product and the supplier.

Ron

Theyre still functioning properly after numerous submersions and many milesof road vibration. So far, so good: Would recommend to others.



by:

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.

Craig J.

4/17/2021

Lights continue to work well. I have adopted the policy of unplugging the light before dunking it underwater. Of course, I also had to train myself to plug it back in before getting on the road - thats what a check list is for, I imagine.



by:

This trailer tail light is a perfect fit. This is the best upgrade I have done to my boat trailer. They are very bright, both parking and brake. I am very happy with this product. Shipping was very fast and I will be back to upgrade the rest of my trailer lights. Job well done!

Tim H.

5/10/2014

Very happy after a year. Great products. Very bright and submersible, what more do you need?Highly recommended, you wont be sorry!Nice not to have a big draw from trailer lights on your electrical system.I cant say enough about them.



by:

Have used this for over a year and the lights have been great. I've pulled the boat trailer over 5000 miles and launched / retrieved the boat dozens of times in saltwater and freshwater with no signs of corrosion or any failed LEDs.

Bill

1/30/2020

Its been 2 years now, a couple dozen more launches in fresh and salt water, and 9000+ miles since I installed the lights and not so much as a failed LED. Very good product.

  • 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.

  • License Plate Mounting Bracket for LED Trailer Tail and License Plate Light # STL57RB
    LED trailer tail light # STL57RB does not come with a license plate bracket but it does have a license plate lens at the bottom. You can use license plate mount bracket # LP10SB with this tail light.

  • 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.

  • 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 # DI34ZR,...

  • Recommended LED Tail Light For Trailer Surface Mount With Multiple Functions

I recommend the Wraparound LED Tail Light for Trailers Over 80" - 8 Function - Submersible - Red - Driver # 271595 along with the 7 Function Passenger # 271594.

  • 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 clearance...

However, it will be more cost effective to just buy the kit so this is what I recommend as you would have spare parts as well.

  • 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.

    For trailer tail lights you need to measure the overall width of your Karavan 6'x12' single axle trailer.
