I fix the motor mounts in my car jump started it test drive it was fine for the first five minutes with the headlights were on I done did my dashboard lit up my high beams kicked on my headlights turned off but my tail lights work and I can't figure it out I checked my fuses on the car in their fine I check the bulbs in their fine and I check the wires that I can see but my dashboard flickers on and off and its been doing that for a couple years if you could or know anything about the problem it would be awesome this is a daily driver and I can't drive at night right now
