Need more details than that to suggest anything.
Did you check the bulbs? Wiring harnesses? Any mods?

If all else fails take it to the dealer.

Did you use a relay-harness? If not, you may have released the magic smoke from your junction box ($700 worth).

most likely you have a bad ballast that sometime fires and sometimes doesn't. Turn them off.. count to 5 and turn them back on. That should do it. If not, cycle them again.

that typically shows up as a signal light on the passenger side that will not turn off even after the car is shut off. Nor will it activate It stays on bright all the time.

you might also want to check the fuse on the relay harness to see if it didn't just blow, that would be easily replaceable. You can tell by putting it through an ohmmeter or just replacing it with a new fuse if you don't have an ohmmeter. I think it should be like a 20 amp fuse, your local auto shop should sell them pretty cheap. I doubt it would be a ballast issue if both of them failed at the same time unless something affected both ballasts to make them both malfunction.

Going to the dealer for this problem is defiantly a no go since the headlights are modded.

Turn them off then on. You checked all your connections and made sure all the wires are still connected first right?
