Ask the Experts about this Optronics Trailer Lights

  • Are Load Resistors Required when Adding LED Lights to a Trailer
    You may not even need load resistors to switch to LED lights. The best thing to do is to try the lights without load resistors first. No need to purchase something you may not need until you know need it. Load resistors such as aluminum # P230004A and ceramic # P230004C dissipate heat through the body of the resistor. Wrapping them with insulation would prevent them from dissipating heat properly. You could put them in a battery or junction box though. Load resistors increase the...

  • Troubleshooting Running Lights on Trailer Not Working After Swapping to LED Lights
    It is not necessary to install load resistors on a trailer that had it's bulb type swapped from incandescent to LED. Most likely you just need to ground the running light circuit or there is a short on it somewhere to cause it to not function properly. First thing you should do at this point is test the 4-way of the wiring harness with a circuit tester part # PTW2993 for voltage on all of the right pins when the taillight signals are being applied. Just like in the video I attached. If...

  • Troubleshooting LED Trailer Lights Not Functioning Consistantly
    For your light tear trailer the LED lights could be the issue requiring a load resistor to draw more power than the LED for correct function, but we don't have enough information to confirm since at times they work fine, or not at all, while at other times they blink. It sounds more like a short in your wiring or a bad ground connection. Normally if it were just the need for load resistors you would have the blinking but they would always still have power. It really sounds like a bad...

  • Does Connector Need to Change When Converting to LED Trailer Light
    Do you mean the main trailer connector? Or what specifically are you asking about? If you have the standard 3 plug that the # STL53RCB uses like part # A47PB you would not need to replace it as this is not an LED specific connector.

  • Do LED Turn Signals Need Load Resistors When Installed on a Jeep Wrangler
    Yes, you will need a load resistor for each LED bulb you install on a turn signal circuit. I checked your order and it looks like you bought a total of 4 LED lights, because of that I would recommend you get two sets of Putco LED Light Bulb Load-Resistors # P230004C-2. I attached installation instructions and a couple pictures for this product that shows how it installs.

  • LED Replacement Light Recommendation For Bargman 68 Round 4-1/2 Inch Trailer Lights
    We have four different round LED stop, turn and tail lights that will fit in the 4-1/2 inch diameter holes in your rear bumper. You could use the Optronics light, # STL23RB, # STL43RB, # STL53RCB or # STL23CCRB. These are 4 inch round lights, but they require a rubber grommet, # A45GB, that allows 4 inch round lights to flush mount in a 4-1/2 inch cutout. Lights # STL43RB and # STL53RCB are sealed, submersible lights if you are adding these lights to a boat trailer. All of these lights...
