Perfect replacement for factory installed lights.
Was able to use factory drilled mounting holes.
Installed in less than 45 minutes. Much brighter than original lights. I believe that they should provide many years of trouble free use.

Its been about a year, the lights have gone through all four seasons here in Minnesota and continue to function flawlessly. They have been a great investment saving me the time and effort needed to replace light bulbs.



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:

Tired of dealing with corroded bulbs so bought these LED units. Same 2" bolt spacing as old one so easily mounted. Spliced wire connections and works great. Super bright! Will see how it holds up to weather. Hopefully will never have to touch it again.



by:

First set of submersible trailer light that have lasted the rigors of salt water. Highly recommend this product



by:

My mistake, thinking they were identical and reversible. That is why they specify drivers and passenger side. Ordered another one and will be all set.



by:

Nice and bright , worked great for my flatbed upgrade .easy website and easy shipping. Ordered from this company for a few years and have never had an issue



by:

still the wrong part, your picture of this part shows a base (where the hole is) shows 3" the one you sent is 2". confusing. need 3" base.



by:

Very impressed! Ordered the STL9RB and the other side twin STL8RB. Etrailer shipped the wrong twin. One phone call and 5 minutes later, the correct part was shipped!

The LED tail lights and side markers (MCL82ADB Optronics LED Surface Mount Marker/Clearance Lights with Reflex) are for a home-built cargo trailer. Decent build, waterproof, and the plastic is of a heavy gauge to last a long time in the Arizona sun. These units are equipped with LED's, and should last a long time.

Thanks etrailer!

One year in, and tail lights are still holding up well in the Arizona sun . . . . . :-



by:

Had to replace the tail light on my motorcycle trailer that vibrated and broke on my last trip (different manufacturer). Just completed a 500 mile trip, including periods of rain. No problems at all. Grat product.



by:

I installed lights on boat trailer in May 2019...
Launched boat several times with water covering lights.
Stored boat and trailer outdoors all winter of 2019/2020.
April 19, 2020 I took boat and trailer to marine shop for maintenance.

LIGHTS WORKED WITHOUT AN ISSUE!

Thank you for selling a reliable, quality product!

GOOD LIGHT WORKS GREAT

The trailer light assembly is exactly the one needed to replace the one on my 19 year old boat trailer.

The assembly arrived in a timely manner and is the one shown on the company web site.

Exactly what I ordered, very simple and bright!

It is the correct item

Great lights. Nice and bright

Good product, good service, prompt delivery, personal touch with etrailer.com



by:

They work as intended. Have to make sure of proper ground.



by:

Very nice lights for the price. They were easy to install and the mounting bolts fit right into my existing holes from my "different brand" lights that were damaged. They are very bright! Not sure if they are "truly" submersible like the add says, as the wires simply go through a manufactured hole in the back of the case, so the wiring inside must be sealed. Either way, I just filled this hole with some regular silicone caulk. As with all trailer lights I would recommend buying or making light guards, as these lights can break easily. Overall I am happy and would definitely recommend!

Thank you! The lights are great, no issues at all, and tough as nails!!! I have them on a 10k 6x10 dump trailer, that I beat the snot out of, gravel logging roads, mud, snow, ice, driving through brush. I just wish my trailer tires were as tough as those lights. Thanks again, and if I ever need anything for my trailers, I will be shopping etrailer!!!



by:

STL9RB & STL8RB Trailer tail-lights. Removed old standard bulb tail-lights, from my small "runaway" camper trailer, and replaced them with these LED tail-lights. The LED lights are much brighter than the old lights. Installation was easy. Followed the instruction video. It took me about twenty minutes from start to finish. They work great and look great.

Still working great.



by:

Installed this and several other lights on a new trailer. Factory lighting and wiring left a lot to be desired, and with the help of etrailer.com I was able to get everything fixed up like I wanted.

Lights work very well - clear and bright red tail and turn/brake lights.

All of the products I purchased its been about 2 years now are still working great. Thanks for checking in.



by:

Looks Great! Works Great! These were added to a 14' Kaufman Dump Trailer that I wanted to use as a utility trailer also, but when completely tarped, the brake/tail/turn lights were covered. So, I added these lights to the side of the frame so that they could be seen when the trailer was securely tarped.

I still love the products purchased



by:

Put these lights on my trailer 1 year ago. Used trailer 1/2 doz. times since the install. This weekend find that the left light running light is out. The right light 1/2 the LED's are out. I had my old $6 units on there for 16 years. Obviously got better service from them.

One of our Customer Service reps, Nikki, has sent you an email about the warranty policy. The LEDs in these lights are covered by a limited lifetime warranty. Check your email for more information on getting the bad lights to us so we can send you new ones.



by:

Excellent product at a great price.



by:

Appears to be of excellent quality and fit. Easy replacement of old bulb type lights. Everyone should retro their lights to LED's. Big safety improvement. Don't have a report on how submersible/water tight these lights will be yet.

Nothing to add, but.... awesome. they are bright and work fine on the boat trailer, even after several dunkings in the lake.

  • Passenger Side Trailer Taillight Recommendation to Match Driver Side Taillight # STL9RB
    The passenger side trailer taillight to match the part # STL9RB is the part # STL8RB.

  • Availability of LED Trailer Taillights That Can Replace 432000 and 431800
    We have LED trailer taillights that have the same 2 inches between the mounting studs like with the part # STL9RB for the driver side or part # STL8RB for the passenger side but we do not have LED versions of the # 432000 and # 431800.

  • Why is the Left Hand Light More Expensive than the Right Hand Light?
    The left hand taillight is more expensive because it contains more LED lights than the right side, due to the addition of the license plate light on the bottom of the light. The white LED is more expensive to produce also and that adds to the cost of the left hand light because the license plate lamps are white.

  • No Right Turn Signal Or Brake Light From T-One Converter on 2003 Jeep Grand Cherokee
    It sounds like your converter has shorted and will need to be replaced. However, more than likely there is an issue on the trailer wiring or light that has caused the converter to short. You will want to check the trailer lights and wiring to make sure there is not any exposed wires or the bulbs need to be replaced. It could be that moisture got into the right side tail light when the trailer connector was connected to the vehicle, causing the converter to short out. This could happen...

  • Troubleshooting Left Side Running Light Problem on a Boat Trailer after Installing a New Tail Light
    It sounds as if you either have a weak ground at the first light on the left side of the trailer that is not working or you have a broken or pinched wire on the left side after the light that is working. You have effectively eliminated the vehicle and trailer connectors by observing the fact that the first running light inline on the left side of the trailer is functioning properly and that all of the other trailer lighting is working. Start, by making sure the lights that are not working...

    What you will need is a Over 80 inch Wide, Square Submersible Trailer Tail Light with License Plate Light, 8-Function, Left, part # ST5RB. For a license plate bracket you will need a Trailer License Plate Mount Bracket, Angled, Rust Proof Polymer - Black, part # LP10SB.

  • Can a Passenger Side Tail Light Be Used on the Driver Side of a Trailer
    Left side tail lights have a clear lens on the bottom to light up the license plate. Right hand side tail lights do not. If you were to use the right hand side light, # STL8RB, you would need a separate light to illuminate the license plate. The left hand side light that matches is # STL9RB. If you click on the last picture on the product page, you will see the lens.

  • 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 #...

  • 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.

  • What Is Wire Size For Parts And Recommended Connectors
    I called the manufacturers to confirm wire sizes. The Optronics lights, Item # STL9RB and Item # MCL76AB, will have 20-18 gauge wires. The Electric Trailer Brake Kit, Item # AKEBRK-35, will have 12-10 gauge wires. I recommend using the Deka Heat Shrink Butt Connectors. For the 20-18 gauge wires this will be Item # DW05743-10 and for the 12-10 gauge wires it will be Item # DW05745-10. If you need additional wire for your project, Item # 10-1-1 and Item # 10-2-1 are available. I...

  • Recommended Taillight for Redline LG440NP Guard for Trailer Taillights
    The Redline # LG440NP steel trailer lamp box works well with the Peterson # 432400 driver's side and # 432200 passenger side incandescent taillights, but I'd recommend going with LED taillights because they draw less power, are brighter and last a heckuva lot longer. If you want to go that route, use # STL9RB for the driver's side and # STL8RB for the passenger side. Per the product description, you'll need to cut a slot in the underside of the lamp box on the driver's side so the license...

  • 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.

  • Are the LED Trailer Tail Lights # STL8RB and # STL9RB the Same Just for Different Sides
    Yes, the LED Trailer Tail Lights # STL8RB and # STL9RB are the same light. Part # STL8RB is for the passenger side of the trailer while part # STL9RB will install on the driver's side. You can also find these LED lights in the Kit # TLL9RK which will provide you with a wiring harness with connectors, a license plate mounting bracket, as well as hardware and quick-splice connectors needed to install the parts.

  • 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.

  • Raft Trailer Left Tail Light is Brighter and Turn Signal Does Not Work with Vehicle Lights On
    Even though you have checked the grounds this does still sound symptomatic of a ground problem. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Also make sure that the new light wires are connected to the correct wires on the trailer. The back of the light housing should indicate the function of each wire. For example, light # STL9RB uses yellow for left turn...

  • Replacement Tail Light Assemblies for 1976 Argosy Camper
    The issue that you're going to run into here is that the lip that you removed is designed to allow you to mount lights on the back because of the curved ends. Because it's such a smooth curve there, you're not going to be able to use something like the Bargman Wraparound Clearance/Side Marker Light - 86 Series - Red - Black Base # 30-86-202. With that said, I'll mention two options for you that you could likely make work by moving the electrical wiring in a bit. First, you could use the...

    This is an issue we run in to quite commonly when installing Combination LED Trailer Tail Light part # STL9RB or any other trailer light. The good news it has nothing to do with the vehicle 99% of the time. The most common cause for this is bad grounding at your lights or at the wiring harness ground. When this came into the shop my first step would be to remove sand down to good steel and replace each ground. That will likely solve your issue. The very dim light coming through is an indication...
