Great customer service with Brandon, easy installation and the the results were amazing. Lights are so much brighter than the incandescents I had previously. Bery pleased!!!



by:

Perfect fit. A wiring diagram might be useful to make sure the wires match up. There is notations on each light which helps.



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 Phone call to etrailer answered all my questions on these lights before I placed my order. shipping was right on time.(5days)

This light is a great up grade to the stocks lights that came with my new "Trailer in a Bag". I am looking forward to these LED's working well with all the bouncing road punishment a small trailer has.
I will report again once I have put on 500 trailer miles

I know that's super frustrating to have to go through placing the order and waiting for it to arrive and then it turns out its the wrong thing, and then having to let us know and then having to go through whatever process to get the correct item sent. I can only chalk it up to human error plain and simple. I am glad to see our customer service team is sending you the correct part. Thanks for bringing this to our attention!



by:

So far so good I have had these lights on for over a year now and have forgotten several times to unplug when launch or retrieving the boat it doesn't seem to effect the lights as they still work fine. Stop and signal is not that bright in daylight but shows up fine in dusk or night. It could be my angle of the trailer that causes this.



by:

Great product for my flatbed l.e.d upgrade lights feel of good quality .easy ordering and shipping



by:

Sending you a pic of my lights I got from you and the hitch with the full wiring system. All works great. Thank you so much. Now it's time to go riding!!

Still working great after one year on my off-road trailer.

  • 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.

  • Troubleshooting Amber Light on Optronics Dual-Face LED Light # STL53ARPB
    The Optronics Dual-Face LED Stop/Turn/Tail/Parking Light # STL53ARPB referenced in your question does indeed feature 3 wires - white for ground, red for stop/turn, and black for tail/running lights. It sounds like you have hooked everything up correctly. The issue with your particular lights actually appears to be on the right side where the amber light is not turning on at all with the running lights activated. The amber light on this unit serves as both the rear turn signal and parking/running...

  • What Gauge Wire on Optronics LED Combination Tail Lights STL9RB and STL8RB
    The Combination LED Trailer Tail Light - Submersible - 6 Function - 11 Diodes - Passenger Side # STL8RB and # STL9RB has 16 gauge wires. You will want to use connectors like the Deka Butt Connector - 16-14 Gauge - Qty 5 # 05731-5.

  • Recommendation For Matching Driver And Passenger LED Trailer Tail Lights
    The driver side tail light that matches Item # STL8RB is Item # STL9RB. This trailer light is the same as # STL8RB but has additional functions related to the driver's side. It has the added function of license plate light. Additional information and videos attached.

  • Will LED Submersible Trailer Stop, Turn and Tail Light # STL8RB Fit Light Guard Tail Light # LG440NP
    The Redline Unpainted Steel Light Guard, part # LG440NP, is designed to fit the Peterson square tail light, the square taillight 440 or the 440L. However I took some measurements of the Light Guard and the LED Submersible Trailer Stop, Turn and Tail Light, # STL8RB (see image) and I found that the light will fit. The light guard measures 5 inches tall and 5-1/2 inches wide, while part # STL8RB measures 4-3/4 inches square. More important the light has two studs on 2 inch centers, the same...

  • Are the LEDs of the Optronics Light # STL8RB Attached to the Lens or the Housing
    The lens of the LED Submersible Trailer Stop, Turn and Tail Light # STL8RB that you referenced is held on with 4 screws around the outside of the housing. The LEDs on the inside of the light are not attached to the lens. They are attached to the housing. Since the light isn't designed for that type of modification it would be hard for me to safely recommend you do that. An easier option might be to install the # 763560 as this is a capsule designed to replace the light assembly of a taillight....

  • 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.

  • 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.

    The Optronics LED Submersible Multifunction Trailer Light # STL8RB that you referenced is a right-hand light and does not include the clear down-facing lens for illuminating your license plate. However, the matching left-hand light from Optronics, part # STL9RB, does include this function. Please refer to the linked photo which shows the underside of part # STL9RB. We also offer a rustproof polymer License Plate Mount Bracket, part # LP10SB from Optronics, to allow installation of both...

  • 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.

  • Can Combination LED Trailer Tail Light # STL8RB be Installed on Either Side of Trailer
    You would be totally fine to use the Combination LED Trailer Tail Light # STL8RB on both the driver and passenger side of your trailer. You'd just need to flip it over like you mentioned and you'd be fine. It will function the same installed on either side. The only reason there's a driver and passenger side is that the driver side typically has a license plate light on the bottom of it.

  • Wiring And Light Recommendations For Small Utility Trailer

I have attached a link to a helpful article that explains trailer wiring you can check out. For trailer lights I recommend using LED lights. they are very durable and raw much less power than incandescent lighting. For the right hand side of the trailer I recommend a light like part # STL8RB. This is an 11 diode light that features...

  • 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 #...

  • Are Load Resistors Required When Converting Trailer to LED Lights
    Converting trailer lights from incandescent bulbs to LED does not require the use of a load resistor. For example, the part # STL8RB would fit and work well without any type of load resistor.

  • Troubleshooting Trailer LEDs that Don't Work that Are Replacing Incandescent Bulbs
    If you tested the LEDs and they work when they have power and ground the problem has to be the wiring of the trailer. Since previous lights worked there it would seem that the problem may be somehow ground related. Some assemblies ground through their hardware and other ground through a wire. I attached a couple help articles that might be informative as well.

  • 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...

  • Matched Pair of Optronics LED 7-Function Trailer Tail Lights
    You can use Optronics Trailer Tail Light # STL9RB as the match for the passenger-side light # STL8RB. These high-efficiency LED lights will provide both brighter output and reduced power demand as compared to standard incandescent lights. Both are stud-mount lights that use a 3-wire design.

  • What Could Cause LED Light Bars to Turn Off and On When Bumped
    Try jiggling the wiring that runs to the lights first. Hopefully that causes the lights to come on or off and the issue is as simple as a wiring connection that's not fully secure. If that's not it and it's an LED setup the solution will be to replace the assemblies as it's a loose wire somewhere in the diodes.
