Do the Optronics LED Trailer Tail Lights Have Built-In Resistors

Question

Question:

I have a 2019 Jeep JL Wrangler. I will use it to tow a 1952 tear trailer. I would like to replace the trailer lights with LED lights such as the ones you have that are a combination turn signal, brake and parking lights such as Item # STL78RB and Item # 2250R. Do these resistors and if so which ones? Thank you

Expert Reply:

The trailer tail lights we offer with LEDs such as the Optronics LED Trailer Tail Light part # STL78RB do not have any built-in resistors. That said, you won't need to use resistors to install LED lights on a trailer. If you were replacing incandescent lights on a vehicle with LEDs that is then were you could need resistors but not for the trailer.
