I wanted LED teardrops. Apparently, they don't make them. I guess building hot rods all my life has made me look outside of the box, so that's what I did.
I started with a new light that picked up online.
If you remove the lens, this is what you have. I took a 1/4" drill bit and drilled the brad off. Doesn't require drilling all the way through.
Once I drilled the brad off, if leaves a blank canvas.
I picked up several of these 7 dollar gems at a local trailer supply.
Just pop off the chrome bezel, to get down to the bare nubbins.
I located the center from each end. There should be about 3/8" between the two.
I use the stepped drill bit to drill the aluminum bases, since they are "O" material, which means it is dead soft aluminum.
