Perfect replacement for my old lights.



by:

Nice and Bright! 10x's better then bulbs. I love them!



by:

Good communication, sent quality parts and correctly. thank you!



by:

Perfect replacement or my existing trailer lights.



by:

Easy to install led lights are nice and bright. great product



by:

Good daylight brightness, installs easily



by:

Very happy about the delivery of this product, I'm impressed on how fast I've recieve my order.



by:

Very good quality. Easy to install. Super bright. I recommend it highly.



by:

Great product easy to install works as described



by:

Great product - much better than standard bulbs which burn out, vibrate loose, and corrode.



by:

Great product, good price, fast delivery. Thanks etrailer!



by:

Nice product. A bit pricey but I hope they will be more reliable than the old bulb type. With extra lights--9 or 10 small lights, I'm hoping that if one fails the others will still work.



by:

Very well constructed and quite bright. Expecting them to last, since there is no hot bulb going underwater like my old ones.



by:

Trailer LightingI had a large choice of items to choose from and was able to locate just the right lights that I needed to complete my trailer. The price was lower than other sites that I was looking at. The products were shipped extremely fast. I would as in the past buy from this company in the future and would reccomend this company to anyone.



by:

Opening the box I thought the order was wrong, I could see a hole into the light where water could enter, but removing the lens showed the lens and circuitry in one piece with the electronics embedded in a clear resin. Really nice design. No chance of corrosion or water issues.



by:

This light is excelent. Very bright and easy to install. Best light for my boat trailer that I've found.



by:

Excellent value for the money, easy to install, and VERY bright. I highly recommend these, especially to replace 12V incandescent bulbs, as these LEDs won't burn out and are completely sealed and self-contained.



by:

These tail lights work very well. Unfortunately they take quite a beating as the trailer is tipped dragging the license plate and banging the light.



by:

Replaced existing bulb application with LED lights. Simple installation, exact fit and look of original, but with LED performance. I would recommend replacing older light sets with these so you can be better seen on the road.



by:

Ordered both left and right matching pair stl9rb and stl8rb , shipping was great came neatly packaged with plenty packing material and shipping cost was excellent in comparison to other sites .
The main reason for ordering was i am using an electronic wiring harness in 2011 Hundai Sonata,the standard tail lights on the trailer were incandandesent bulbs and pulled too much current kicking the breaker in the electronic control module on wiring harness , i was aware L.E.D.s draw much less current so when these plus marker lights were replaced .PROBLEM SOLVED , THANKS E-TRAILER



by:

Awesome idea! I've used them for the last several years but, unfortunately, I broke the lens when I hit something. My old ones didn't have replacement lenses, my new one do. If I break them again, it will be a lot cheaper and easier just to replace the lens instead of the whole tailight.

LED Submersible Trailer Stop, Turn, Tail and License Plate Light. The LH and RH taillights that Ive been using for a year now still work perfectly theyve been submerged hundreds of times! Theyre several times brighter than my old LED lights-a real safety factor! The only thing Id like to see would be a non-license-plate version of the LH unit for states like MN that dont issue trailer license plates. I had to tape over the illuminating lights on that side. A truly great product!



by:

Beautiful tail light. Very bright for the brake and turn signal. Fitted it on the back of my trailer with an L bracket.



by:

All new wiring on a trailer rebuild. These junction boxes make the job so much easier and faster. Now when i troubleshoot wiring issues im chasing one wire at a time. Oh and now the wiring goes in a location that works for me



by:

Rebuilding a used trailer with no idea what axles it had. Contacted customer service and they walked me through getting the right brake kits, bearings, and hubs..excellent customer service



by:

Installed the new lights today. Easy peasy. I grew up on a farm, in the country, and have been fixin' and futchin' with trailer lights since I was 6, it seems (I'm 74 now). Hopefully this is the last time I'll need to fix the lights on this particular trailer.

  • Recommended Replacement Trailer Lights With Side Lights For Small Utility Trailer
    We have just what you are looking for. I recommend the LED Submersible Trailer Stop, Turn and Tail Light, part # STL8RB. This is for the right side of the trailer and is a stud mounted LED light. It has the side marker light that illuminates when the running lights are powered. For the left side of the trailer you will want part # STL9RB. I have attached a product review video and have also attached a drawing that shows the dimension for these lights you can take a look at.

  • Looking For Square Tail Lights Made In The USA
    Hello Mike, thanks for reaching out. The Optronics lights like the # STL9RB you mentioned are made in Taiwan. We do have a very similar light that is made here in the USA, the Peterson LED Combination Tail Lights # M844L for driver side and # M844 for the passenger side light.

  • Peterson Combination Trailer Tail Light - Can Incandescent Bulbs Be Replaced With LED Bulbs?
    Hello Gregg; yes, the incandescent bulbs in the Peterson Combination Trailer Tail Light # 432400 can be swapped out for LED bulbs. This light uses an 1157 bulb for the tail light and an 1156 bulb for the turn signal. Here is what I recommend for bulbs: - 1157 LED Bulbs - 360 Degree - Double Contact Bayonet - 600 Lumens - White - Qty 2 # ARC93FR - 1141/1156 LED Bulb - Single Contact Bayonet - 360 Degree - 210 Lumens - Cool White - Qty 2 # DI85VR While replacing the bulbs is possible,...

  • Replacement Tail Lights For a 2004 Sea Lion Boat Trailer S 16-1500
    Thank you for the picture that is very helpful since I cannot always see what trailer manufacturers used on their trailers. The LED Combination Tail Light Kit # TLL9RK may be your best option depending on the condition of your current wiring. This kit includes both tail lights, a license plate bracket and 25' of wiring for the tail lights. If your wiring is still in good condition the Drivers # STL9RB and Passengers # STL8RB side tail lights are available separately. I do recommend using...

  • Replacement Waterproof Tail Lights For a Malone Boat Trailer
    I recommend switching to the Optronics Drivers Side # STL9RB and Passenger Side # STL8RB tail lights. These lights are LED with multiple diodes and have a sealed waterproof construction. If your Malone trailer uses the push style connectors I recommend replacing them with the Butt Connectors # DW05744-10 which will give you a watertight connection.

  • Submersible Right Hand LED Trailer Tail Light Recommendation
    If you want a submersible tail light I would recommend the LED Submersible Trailer Stop, Turn and Tail Light, 6-Function, 11 Diode, Right Hand, part # STL8RB. The # STL28RB you referenced is not submersible, and I would not recommend it if you need a submersible tail light. You may also be interested in the LED Submersible Trailer Stop, Turn, Tail and License Plate Light, 7-Function, 14 Diode, Left Hand, part # STL9RB, if you needed the left hand version of the # STL8RB.

  • Does Optronics Tail Light Lens A90RB Include a Clear Portion for a License Plate Light
    This lens is meant to be used as a replacement to the Optronics tail light, part # ST90RB. It does not have a clear portion for a license plate light. You are looking for a light like Optronics part # ST9RB or part # STL9RB. You could also use Optronics part # ST17RB. I have linked to these parts below.

  • What are the Measurements of Optronics Replacement Side Marker Lens # AL9RB
    I went out to the warehouse and pulled the Optronics Replacement Side Marker Lens # AL9RB. It measures 2-13/16 inches across, 2-1/8 inches tall, and it is 3/16 of an inch thick. The mounting holes are 2-5/16 inches apart on center. The lens is for # STL8RB and # STL9RB lights which no longer use a gasket. The LED light system is encased (sealed) in plastic making the LED light fixture itself waterproof.

  • LED Trailer Taillight Replacement Recommendation
    LED lights are more durable and can withstand more than incandescent bulbs. Regular bulbs are pretty fragile by comparison. That is not to say that the LEDs are indestructible but they will hold up better than regular bulbs. I attached a page that has all of the LED trailer taillights we offer that could possible fit. The part # STL8RB and # STL9RB are very popular options that you might consider. I attached an install video for these lights for you to check out as well.

  • Left Side Boat Trailer Tail Light Does Not Have Power when Bulb is Installed
    The most likely problem is going to be a bad ground. Without the bulb in, there is no draw on that light and ground issues normally show up when there is a load on the system. If you recently install a plastic license plate holder in between the light housing and the trailer frame, that can cause this problem (if the lights ground through the mounting studs). The solution will be to run jumper grounds (no matter how the lights ground to the frame) to the main trailer connector ground....

  • Installing LED Lights On Trailer Connected to 2003 Dodge Dakota with Incandescent Lights
    The 2003 Dodge Dakota does not have a converter box as a part of the trailer wiring. Here is where confusion comes in and where ambiguity comes. Some LED lights may have zero issue plugging directly into the system based on the trailer length, ground connections, and number of LED's in each light fixture. Due to enough power draw. Other trailers may not have enough power draw and may have hyperflashing issues requiring load resistors either on each line or through a converter like #...

  • Why Does the Optronics Driver Side Tail Light STL9RB Have More Diodes Than the Passenger Side STL8RB
    The reason that the Passenger Trailer Tail Light # STL8RB has 11 diodes and the Drivers Side # STL9RB has 14 diodes is because the driver side light has an additional function; license plate illuminator. This is why you see a difference in the amount of diodes. I have attached a picture of the underside of the driver side light so you can see the license plate illuminator. I have attached some review videos as well as an installation video for you to check out.

  • Replacement Lens for an Optronics STL-8RB Combination LED Trailer Light
    I spoke with Optronics to confirm: these lights are not designed to have replacement lenses due to the fact that they are waterproof lights. Opening the lens would take that away, so they were not made for that. On the bright side, these lights have a lifetime warranty, so if you speak with Optronics, you could possibly get a replacement light. Or, you can speak to whomever you purchased the light from about their warranty policies. In case it was us, I have linked to our customer service...

  • Replacement LED Light Installation on Trailer Cargo Platform
    If you intend to wire your new additional lights into the existing lighting circuits on your trailer then I do recommend using LEDs since they will add a minimal additional power draw on that wiring. Since you probably have no way to know for sure about the power-handling capacity of that internal trailer wiring using high-efficiency LEDs lights is the safer way to go. It is okay to mix incandescent and LED lights but note that they typically have different brightness levels; LEDs usually...
