Hid problems

[americanracing20]

I have been having alot of problems with My hid headlights when it's dark the automatic light system will turn the headlights and sometimes only one light will turn on so i am constantly messing with them any suggestions?

turn key on(don't crank the truck), turn them off, start truck, after motor idles down turn on and drive off. works like a champ and the hid's will always be at full power

One of mine keep giving me trouble so I replaced the ballast problem solved.

Try a relay harness. If that doesn't work could be a bad bulb or ballast. Switch the ballast to the opposite side to see if the problem follows the ballast or the bulb.

I had a similar problem and ended up with a burnt out bulb on the passanger side. So after i got replacement bulbs, I started to set the parking brake before I start the truck and then disengage it once the truck is started and it works perfectly. Or like stated above you can get a relay harness.

why would you need a relay harness for a hid head light swap? your oem halogen's draw around 55 watt's per bulb and most generic hid kits draw 35 watt's per bulb. So its 70 watts for 2 hid bulbs vs 110 watts for halogen's. my vote ballast

Because it allows them to get full power. The NNBS especially, uses the headlights as driving lights with low power usage. It can cause havok with the ballasts.
