I used just plan ol' auto parts store parking / turn signal lights. The single pole lights not the double ones ( those little bumps on the bottom of the bulb ). They look cool when just the park lights are on turns the whole headlamp assembly orange. I guess you could use any color you want. I have a pair of amber fog lights also but debating whether to put them on. Hate to drill the holes and be disappointed. Looking also at those headlight grills ?
My turn signals are just used for that alone not with the parking lights.
