h i d are going crazy need help

well i just put some 12K hids on my 06 gmc. and they had been working great. then they they started to flick, then started to like strobe lol. what could be the prob?

Could be a bad connection somewhere, or maybe a relay going bad.

i checked the connections, where would the relay be at

1st I would test to see if its a voltage issue all you have to do is to disconnect it from the the ballest from the factory harness ad grab the power and ground from the battey. if the flicker goes away then you have to use relys. if not swap ulbs left to right unless they both flicker.

i dont have a voltage meater, and they are both flicker. it will stop and start back up agin

unplug them and run one to the battery
