Going back a good number of years, I use to own a KENWORTH K100. when I sold it I took off my driving lamps. there were 8" round an had louvers in them for directional adjustment!!! well I was sick of all the HIGH BEAMS comming at me. I put them on my personal truck.
(the wounders of youth.) now I just drive around an BLESS them all as they drive by.
Ill find a pic of that truck.
GOOD LUCK GOOD DRIVIN
P.S. FOG LIGHTS are YELLOW
DRIVING LAMPS are WHITE
