Hey guys I wanted to ask your opinions because some of you seem to have pretty good ideas.

Several years ago I bought a brand new tool box and decided I wanted to attach my backup lights to it. So I drilled holes in the top of the lid and connected the lights. One on the left and one on the right. Each has 3 holes; 2 screws and a hole for the wires. The wires all connect in the toolbox and I ran them through the bottom and through the bed.

Anyways I want to take the lights off and fill the holes so water will stay out. I guess I could fill the wholes with the screws and some sort of a sealant. The holes aren't big so could you just weld the holes shut?

Anyways like I said any opinions or ideas would be awesome.

 

Weld patches in and plug weld the small holes.

 

yeah id get something about the diameter of a washer, weld it to the inside, and fix the hole on the outside with weld, no risk of burning through and making it worse if your not an experienced welder

 

I did this to plug the leftover holes for a diamondplate truck box....

Take an old beer can and cut the can into a few 2x2 squares. Dab some seamsealer on one side and push it flat over the hole until it squeezes out the sides, then smear the residual over the top of the square patch.

 

Buy rubber plugs at the parts store. I do not think i would wast the time or money ( if you can't weld it your self)
