Expert:  Gary replied 9 months ago.

can you tell me the wire colors and the drivers side has one bulb with 2 filaments in it correct ?

im just being sure as they had alot of different wiring set ups and bulb set ups for this year

Customer: replied 9 months ago.
The wire is blue and black. One bulb in each light with one filament. These were replaced
Customer: replied 9 months ago.
One wire is green and one blue.
Expert:  Gary replied 9 months ago.

does the black show a good ground ?

and with the low beams on does the low beam other wire show 12 volts ?

Customer: replied 9 months ago.
I have to get a tester tomorrow. I don't know how to do it.
Expert:  Gary replied 9 months ago.

if just the drivers side bulbs will not work then those drivers side bulbs are missing power or grounds

two wires on each bulb and to turn the bulb on one wire needs to be 12 volts and the other a good ground
