Is Peterson Trailer Light Kit # M540 All that is Needed to Install Light Kit on Trailer
Updated 01/05/2026 | Published 09/09/2024
Question:
Hi! Im planning on rewiring and putting new lights on a 5x10 utility trailer. I just bought the 118269 with a 4 pole connector to connect to my vehicle, and need to connect to it. Would this be all I need to do that? https://www.etrailer.com/Trailer-Lights/Peterson/M540.html Also, do you have any install vids or wiring diagrams you could send? Thanks!
