Optronics STL37RB LED Combination Tail Light Dimensions

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.


PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

No problems during the past year, of course it is a trailer, that spends most of its life at rest.



by:

Product is well built, the packages got here a day ahead of schedule which helped me get the units installed in my boat trailer ahead of a trip I was planning to take. The lights fit tightly in a custom molded area of my fenders. The website directed me to these LED lights as a replacement for the old 1057 bulb type lights.



by:

LED trailer tail lights are the only way to go for good lighting! I’ll definitely come back to ETRAILER for my future trailer supplies!



by:

In use over a year now with no issues. Nice and bright on my boat trailer that I use 40 plus times a year.



by:

Perfect fit for my trailer. Nice bright lights. Thanks for a great product.



by:

A perfect replacement for the OE trailer light on my 2001 Ranger 620VS boat trailer.



by:

This light was a direct replacement for the left side of my 23 foot trailer. Light was ordered, shipped, and installed in 3 days. Worked perfectly.
Just a word to the wise though. Even though the light is rated submersible, one should always disconnect the trailer power cord before launching boat, and wait 15 minutes after recovery before reconnecting. Just good practice.

Yes, the lights still work great. Thanks for asking.



by:

OK, so I broke one of these cool Aero LED lights on my utility trailer. Ground guide said, "C'mon back!," so I did. Bummer. The good news is etrailer always comes through and at a good price and fair shipping rates, so I'm already (legally) back on the road. It's nice to find a company that does more than say they care: etrailer delivers. I'll be back (but I hope not TOO soon). :-)

I sold that trailer to a friend a few months ago, but I saw it just last week. We used it to haul some landscaping materials, and I noticed it had another broken light, so I told him about etrailer.com. I imagine youll be hearing from him soon.



by:

LED lights are bright. The lights fit well onto my boat trailer.
Hopefully they will outlast other sealed lights previously installed.
Submersible lights should last a long time. I hope these do and don’t leak water.
Time will tell, as they have not been tried by me.

Lights are working very well on the boat trailer. No failures which is good.

Replaced the original tail lights on my boat trailer. Exact match for size, mounting. Wired easily, so much brighter.

Super - no more bulbs getting wet and blowing



by:

Product was as described on web site. Exact replacement and easy to install. Best price of any I looked at on line and you were lower than all others (including the shipping) than any other price for just the light.
I will definitely buy from you again when I need trailer parts.

Great



by:

Item was received quickly and packaged well. Customer service is always on point.

Before purchasing these lights for my boat trailer, I had gone through two sets of lights with incandescent bulbs trying to find lights that wouldn't fill with water and cause damage to the bulbs and sockets. After a year of use, these lights still never leak when the trailer is put in the water. And the brightness of the LEDs is a huge improvement over the incandescents they replaced.



by:

I recently ordered this light to replace one that had been damaged by water intrusion on my boat trailer. The original light that came with the trailer (same as the one I ordered from etrailer) lasted about about three years. The trailer is used primarily in a salt water environment and water got inside the light through the clear lens for the license plate light on the bottom. Once water got inside it damaged the LED's as well. The light without the license plate light worked fine until I switched it out. Overall, I think these lights are good in a fresh water environment and will last much longer than they will with salt water use. These light are bright and should look good on any trailer.



by:

Order these boat lights for a friend of ours boat trailer, they arrived sooner than we expected was so easy to install and works great, looks awesome, very pleased.

I called first to see if they carried these taillight and the employee was so nice and helpful, she offered to send a e-mail with the link to order the tail lights, very polite and concerned about our purchase.

We would definitely recommend this company and very impressive with the employees that helped make sure we got the right items we needed.

If I could give them l0 stars I would. Thank You.....



by:

It was delivered within a few days and I was kept up to date in its expected delivery date. It works well, as good as OE.



by:

Great replacement light for older Ranger Boat Trailers. Before the round led lights for the fiberglass fenders there was a Wesbar #105826. Can't find them anymore so etrailer recommended these lights as a replacement. They fit in the fender pretty well. I did have to drill new holes for the mounting bolts lower than the original, no biggie. The visibility is vastly superior to the old incandescent bulbs. You'll probably wonder why you hadn't changed them out sooner as I did. Ordered a pair, first shipment had one broken in it, etrailer sent me a new one quickly and emailed a return label. Communication was quick and pleasant. Highly recommend these folks, have dealt with them previously and will again in the future.



by:

Thought I had a problem after the trailer was idle for a few months, but it turned out to be a loose grounding wire. Satisfied.

The trailer has been outside.all year and the.lights still work great.



by:

Bought a brand new trailer and from the get go some of the regular lights were intermittent. Finally had enough and ordered LED's to replace them all; have not had a single light issue over a year later. All were direct drop in replacements, fit and look great. Thanks etrailer.com!



by:

Awesome company to do business with will by again



by:

I recently purchased this item to replace the incandescent version of this light that no longer worked. Installation was quick and easy. The lights are extremely bright and I can easily tell from the driver seat of my truck that they are working. In addition to this light, I also purchased the STL36RB for the passenger side so that I'd have LEDs on both sides of my trailer. I recommend making the jump to LED if you need to replace your old lights.



by:

I upgraded to this light set 5 years ago and have been very satisfied with their appearance and performance. They are very bright and distinguished just as many vehicles LED brake lamps are. They are a solid red and do not project the pinkish appearance that some LEDs I examined appeared. The LED's are well sealed into the lenses which prevent water from intruding even if the primary black housing gets cracked from an external force such as a car jack in my case. I purchased this LED lamp because I bumped the fixture with my car jack and broke the side lens, however, the main LED housings remained sealed, intact, and fully operable. I am rather finicky, thus purchased the replacement. If you are looking to upgrade to an LED trailer light, I highly recommend this product and series as they are easy to install (it took me about 5 to 10 minutes), do not fade or weather over time, and are very resilient. I looked at many sites to buy them from, but etrailer.com had the best price, shipping was very fast, and the product was well packaged in the box for its journey to my home. Buy them, you will not be disappointed! Thank you etrailer.com for providing a great product at a great price! They are already installed, look great and as if it was never replaced as compared to the other LED tail lamp, and are ready to go.



by:

Product was exactly as described in all the detail - a brand new genuine Optronics taillight. Ordering was easy and delivery was prompt. I would use etrailer.com again.



by:

Prompt delivery and it fit my trailer exactly. Had to use my original mounting bolts because I didn't discover the new ones hidden in the bubble wrap until I was discarding the shipping box. (not a big problem)
May I suggest including wire connectors with the light. A trip to the hardware store would be avoided.



by:

This was a perfect match for my trailer. I carefully hooked it up and it is working fine.

For some reason these were hard to find but they match the trailer so I was glad I didnt have to replace both. Taillight has been working fine.Thanks for checking in.
