Yesterday on the way to work, it was dark enough in the morning to warrant firing on the headlights.
Fired up first time and aside from the alignment being (way) too low all was good. 10 minutes later, a at a stop light I noticed them flickering in the reflection of the car in front of me.
This continued for about 30 secs and I just turned them off to prevent any damage.
I have the ballasts screwed and double-sided taped on and the relays fixed with double sided tape. So I don't think its vibrations or anything?
I have one live cable coming from the battery and then have connected the two relays to this. Both relays are grounded to proper chassis ground locations - not going back to the battery.
It is the XenonDepot XtremeHID kit I'm running.
