Go through your fuse box.

 

Did you plug the ballasts into the factory headlight harness...mine did the same thing...you need a constant 12volt supply and a relay for each light.hooked mine to the positive aux terminal used for boosting ..ran a trigger wire from a park light to each relay and now they work mint.sometimes the lights flicker too if you plug into factory harness... voltage varies.
