Jim, I too have used LED micro lights for the turn and high beams in the location you're suggesting.
Mine are smaller 6mm(1/4") approx.
I still need to get a blue one for main beams.
I'll try and get some pics tonight when I get home from work.
You need to watch about your line of vision, they're really bright!
My turn signals light up the whole cab!

To quote an often used saying "measure twice cut/drill once" !!
