Ive used Optronics for the past 15 years. They were one of the first to come out with LED. They used to have a Lifetime warranty, I just threw my second free set away, but not any longer. They last right at 4 years on my boat trailer before they go haywire or half the LEDs quit working. Would not recommend.

Thanks for the info. According to Optronics site and catalog, the LEDs on those lights are covered by a Lifetime Warranty. It looks like you did not order those from us, but you should be able to contact the retailer you bought them from or Optronics directly to get them taken care of.


by:

I'm happy with the service. etrailer shipped the items out quickly and they arrived in working condition. This is the second time I've used etrailer and their prices and service have always been excellent



by:

The Product came in earlier then expected (with regular shipping)
and was in a neat and nicely packed shipping box. It arrived in perfect condition and price and shipping was less then other sites I had checked. I would defineately recommend e-trailer for all future puchases. In addition the ordering process was very easy as well.



by:

My old bulb and socket trailer lights vibrated loose every time I came down my dirt road leaving me without taillights most of the time. These new lights I got from you are much brighter and I have no vibration problems. I am extremely happy with these lights and the price was right too. Thank you for a great product....sincerely, Dave S.



by:

My right hand boat trailer light was cracked so I decided to just replace this one tail light. After I installed it I realized how much brighter it was than the left hand LED light I did not replace. I will now be replacing the left hand light as well.

  • Can Tow Vehicle with LED Lights Connect with Trailer that has Incandescent Lights
    Assuming the lights and wiring on your older trailer are in good condition you will not have any issues connecting with and powering its standard incandescent lights with a tow vehicle that is equipped with LED lights. The difference in light assemblies used on the vehicle and trailer will not cause any problems with function or power. If you can tell me the year, make, and model of your tow vehicle I will be happy to recommend a trailer wiring harness if you don't already have one installed.

  • All Trailer Lights Blink When One Turn Signal Is Activated
    The most likely cause for the incorrect behavior of your trailer lights, where activating one turn signal causes all trailer lights to blink, is an insufficient ground (or a short to ground) on either the vehicle or the trailer. Since you re-wired your trailer, you can check for a secure ground connection at the trailer connector. Make sure the white ground wire is firmly secured to a clean bare-metal surface that is free of paint, rust and grease. Next check that the ground wire for the...

  • Troubleshooting LED Lights Not Working On Trailer
    The first thing I recommend doing is to check that the ground wire for the lights is securely attached to a clean metal surface on the trailer frame. A loose ground wire will keep the lights from working. If the ground attached to the trailer does not give you an adequate ground, you can run the wire up to the ground circuit on the trailer connector. Next, you want to make sure the wiring on the trailer is wired correctly and wired by function, not just by color. I recommend using a...

  • How to Wire LED Replacement Trailer Lights
    If you are looking at and LED Trailer Tail Light like part # STL8RB, then you will not need a converter to make it compatible with the 4-Way Wiring Harness on your truck. You will need to figure out the wiring on your trailer to make sure that you get all of the wiring done correctly. You can use a Circuit Tester # I26 for that purpose. All you have to do is hook up your new LED lights using the following information. Brown is for tail lights Green is for stop and turn White is for ground The...

  • Troubleshooting Dim Turn Signals After Installing Load Resistors
    It sounds like the ground connection may need to be improved. You want to make sure you have a bare metal to metal ground free of corrosion or debris. Load resistors should not have caused them to dim when installed properly. I've attached a photo of the installation for the Putco load resistors # DI34ZR to assist. If you did install this way, let me know and we can continue to troubleshoot.

  • What Would Cause Trailer Wiring To Flash or Blink When Hitting Bumps in Road
    Your trailer lighting is flickering because the wiring of the trailer is grounding through the hitch ball and coupler and not through the ground wire circuit. When you hit a bump the ball intermittently stops making contact with the coupler which stops the lights from working. What you can do try improving the ground wire that comes from the main harness of the trailer to the frame and you should see it start working normally.

  • Troubleshooting Trailer Running Lights Circuit of Vehicle Fuse Blowing with Ground Continuity
    Finding continuity to ground on the running light circuit of your trailer indicates that the circuit has a short to the frame of the trailer most likely and is your problem. What you'll need to do is trace the circuit starting at the assemblies or connector and look for a short between the wire and the frame of the trailer. This is a very common problem and the solution is finding where the exposed wire is that's touching the trailer frame and fixing as needed. I also attached a help...

  • How to How Trailer Taillights Get Wired Up
    Trailer wiring colors can vary from trailer to trailer so it's not a reliable way to wire up a trailer. You will want to first determine which wire of each taillight signal carries the brighter and dimmer circuits. The dimmer of the two will be for the running lights and the brighter will be for the stop/turn circuit. Next, you will want to use a circuit tester like part # PTW2993 to test all of the wires on the trailer as it is connected to a tow vehicle and all of the taillight circuits...

  • 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.

  • Upgrading Camper Lights to LED and Clearance Lights with Brake and Turn Signal Functions
    You can upgrade to LED lights but what I need to know is if the camper has the brake lights and turn signals on the same bulb or if it has separate amber turn signals. And if the camper does have combined brake and turn signals do you want to keep it that way or do you want to have separate turn signal and brake light circuits? We have several options for double tail lights, such as # CE86FR, and even some triple applications such as # 47-84-005. Depending on if you want combined or...

  • Not Getting Turn Signal Function When Using LED Bulbs On A Trailer
    LED bulbs have little resistance on their own, so when used with turn signals they can create a hyper flash situation, which is a fast flashing of the bulb. To determine if you will need a load-resistor kit like a LED Light Bulb Load-Resistor Kit # DI34ZR, you will install the bulbs and when the turn signals are activated, if the bulbs hyper flash you will need to install the load-resistor kit. This kit will prevent the turn signals from hyper flashing. You will need one kit for each LED...

  • Troubleshooting LED Trailer Lights on 5 x 8 Foot Tilt Trailer
    If you used the Trailer Tail Light - 6-Function - LED - Submersible - 11 Diodes - Red Lens - Passenger # STL8RB then I recommend running a jump wire from the frame ground at the light to the mounting hardware on the unit. It sounds like the ground is not making a full contact, so the 12V battery is giving enough power to overcome the ground issue. I've attached a video of this particular light and the ground wire connection to the mounting hardware. The other possible issue is that...

  • Troubleshooting Trailer Wiring That Activates The Hazards When Using The Right Turn Signal
    Hey Justin, When you say it's triggering the hazards what exactly do you mean? Is it flashing the smaller clearance lights on the trailer? Is it just on the right side or the whole trailer? Most likely the converter box for the trailer wiring harness on your Highlander is malfunctioning and sending the wrong signal back to the trailer. You can't do much to fix this unfortunately besides replacement if this is the case. If you have the factory towing package you can swap out the wiring...

  • 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...

  • 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 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....

    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.
