Anyone use these pass throughs in the bed of the truck to mount lights for bed lightning? I have 2 of them up against the cab area of the truck. So these would be pointing towards the tail gate.

I'm thinking a oval led backup light would work.

 

Looks I may be the first one to do it lol

 

Is there enough room behind them to mount anything or run wires?

 

Yes, between the cab and bed there is like 1.5"

 

Most people do down the rails of a tonneau cover system, or down the cab rails, because if you put something in the trunk and slide it forward, the bed is now dark.
