I recently bought my car with some blue/green reverse glow gauges yet they dont light up at night. I took the part off under my steering wheel and found the **** for the brightness and switch for blue or green. There was one wire that was not sautered on and i turned my lights on and connected the wire. There was still no blue light so i was just wondering if there could be a different solution that any of you guys know. Still can only post in here since im a trial member. Ive been a trial member for about 2 months so when can i become a real member? Thanks for your help.
