Mini strobe ground

[Daley Construction]

Hey Guys,

I’m going to install some mini amber strobes on my equipment trailer and I wanted to know if I need to run the ground back to the battery or if I can just ground to frame at each light?

The rest of the led lights on the trailer are just to the frame

I always ran power and ground to every light and electrical source.
My thought was,,,the trailer can rust to the ground but the lights will still be working.
Also, have you (or anyone) ever trouble shot a wiring issue on a trailer with a bad ground? Only takes another wire and a little more time but its worth it.
