Default HID Head Scratcher

So bought new headlights (depo) and new HID bulbs. Headlights have been adjusted, bulbs have been replaced twice now, ballast have been replaced, fuses/relays have been checked. I'm using Hella Ballast made in Germany! But for some reason my left headlight is super super bright. I have tired everything including grounding the bulb. Any ideas???

Uninstall PnP hid kit/crappy knockoff housings.

Install correct bulbs in correct housings.

****ty halogen optics + pnp hid kit = doing it wrong.
if you like how the lights look, crack them open and do a retrofit.

My guess is one light has a bad projector or something out of alignment.

Not that I disagree with the idea of doing it right (via proper retrofit). Isn't the depo headlight a replica of the USDM reflector low/high? If so, it's likely that the hid capsule from the kit + reflector geometry combination not having the minimum dimensional tolerance to at least be consistent from left to right units.

Like the ballast suggestion, try switching the hid capsules left & right to see if the problem is switched.

Either way, replace afterwards.

Post #13 in this thread seem to be a good example of stock my2008 halogen projectors with HID kit. Even though it is a projector, the difference between the halogen filament and hid capsule arc was enough to cause glare above the cutoff.

In some cases, there is no glare above the cutoff, but if you look at the concentration of light intensity below the cutoff (i.e. on the road and on the sides), putting a kit will result in a reduced lighting benefit.

not that I agree with hid kits, I will still try to help troubleshoot.

Are they bi-xenon? with a drop-down cutoff shield? the little actuator could be stuck down.

Are you running this off of factory wiring still? or a harness with a relay?
Battery is on left side, therfore less wire, less resistance, brighter output. since the factory wire is so thin. (not a likely scenario)

If they are not bi-xenon, then it could be a defector projector housing, defective lens, improperly seated lens.
