Installation of Optronics TLL12RK LED Trailer Taillights  


Hi I am looking for a simple plug and play trailer side wiring harness for the TLL12RK oval led lights you guys sell for a homemade utility trailer.. not coming up with anything, I just want to install these 2 lights on the back of the trailer, no marker lights or reverse lights or anything fancy, trailer is about 8ft long.. thank you

Although there isn't a plug and play harness available, wiring up the # TLL12RK taillights to a trailer harness like # A10-4225VP would be extremely easy, as you can see in the provided video where my buddy Jake shows how the harness is installed.

The wiring pigtails included with the # TLL12RK would connect as follows:

• Red wire on pigtail connects to green wire on right side, yellow wire on left side
• Black wire on pigtail connects to brown wire on both sides
• White wire grounds to the trailer frame using the provided ring terminals

To protect the connections from moisture and dirt, I'd recommend using heat shrink butt connectors like part # DW05743-10.

The lamps themselves would install into a 6-3/4 inches long by 2-1/2 inches wide opening.
