alright both my passenger high and low beams both work. However on the drivers side only the high works. I tested the ground and the red with yellow strip wire together with a circuit tester. The test came out negative. I also checked the fuses. I checked both 20 amp fuses in the fusebox under the hood for both headlights and they were good. The black wire doesn't seem to be a working ground also because i tested that with another light. Help me out this has frustrating me for hours.
