Question:
Hi. My wiring harness has the flat 4 wire type connector. I want to hook-up a magnetic trailer light system. What do you recomend? All of the systems Ive found require the round type connector which I dont have. Thanks

Hi Roger!
What you are looking for would technically be referred to as flat tow lights on our site and we definitely have options for what you need. I wasn't sure if you were wanting LED or incandescent, so here is one of each:
LED:
Optronics Universal Magnetic Tow Lights - Red LEDs - 20' Wiring Harness with 4-Way Flat Trailer Connector # TLL21RK
Incandescent:
Optronics Universal Magnetic Tow Lights - 20' Wiring Harness with 4-Way Flat Trailer Connector # TL21RK
Both of these only need a 4-flat to plug into, have a 20 foot harness, and have strong magnets.
What are you planning on using these for?

I forgot to mention that I want it to be wireless. Thanks, Roger
