My pathetic reverse lights..........

The back up lights on my Yukon are pathetic…can I add a couple of small fog lights to the back and wire them into the harness to activate when the reverse lights come on? I may have to up the fuse an amp or two; but is there anything else??

I put this on my F350 to solve the same problem. It’s impressively bright.

Just wire into the backup light circuit - no need to up the fuse rating.
