Button cover

I recently installed KC lights on my truck and wondering if there are any special covers I can use for the button it came with. It’s a little circle size and wondering if there’s a black button with a hole that would fit over it or should I just drill a hole

 

Just drill a hole in the blank you took out? I think that's your best bet.

 

Welcome aboard @dylanmanka , it appears to be a single on/off switch could be SPST or DPST. What I'd do is find a switch that fits in the hole, trim out the original dash piece you removed, fit the new switch to that and ditch the round one. :-D If in doublt go with a DPST and just don't use the other two poles. One like this, make sure it fits . . . the one pictured has LED's in it too.

 

CH4x4 makes factory style switches that fit perfectly in the slots.
