no wiring needed as the leds take less power than the standard bulb so just plug in and away you go ,they are the 501"s but are polarized so if they dont light when installed rotate the lamp holder 180 degrees and reinstall .
Don't you want to paint the back of the outer visor ring white too, so that it reflects back to the numbers on the mask as well as onto the needle? Or maybe silver foil the back of it with some plumbers adhesive foil so that it is more reflective than the inner ring, that way it might hopefully reflect as brightly as the inner ring does even though it has a smaller area. Looks great.
Thanks for the help guys! It's all a learning curve and i really appreciate the help/replies. I was already thinking of trying foil as it would be much more reflective, but i had no idea there was such a think as 'Plumbers adhesive foil' so i just looked it up...Awsum!! Thanks again!
