Yellow headlights

You can get yellow tinted clear coat, in the form of VHT Nite Shades spray can. Or if you are trying to run a yellow highbeam on a 4 headlamp car you can replace the highbeam bulbs with a Wagner 4412A. These are a foglight bulb and do put out quite a bit of light, although you will have to make your own "jumper" connectors to power them. I can go more into detail if anybody is interested. Used to run these on my old Datsun 521 pickup for a little more light at night.
