My wife got me a set of these for xmas and they installed easily, except now sometimes when i start the truck the D.S. light wont come on in automatic mode, i'll have to turn them on once or twice manually to get it to come on.They will work like their supposed to maybe one time in ten.. I put in 5000k in my driving lights and my low beems. I took it all apart and re-installed, but no change, Do yall think its the ballast or is there different voltage from automatic to manually turning on the lights?? ugggh!
