ok first of all... i'd suggest that u disable your DRL, coz if u keep your DRL, ur HID ballast will die fast (since DRL is letting less power to the lights, hence to the ballast with your current setup, not enough power to the ballast = ballast wear out fast), as u also found out that when your lights are dimmer when your light switch is at the off position.
OR, u can do something to the fuse box and let to DRL to have 100% low beam power.

now, on top of that, get new fuses for the headlights (low beam), get both to 15amps or 20amps.... stock is 10amps which is limiting the power to the lights. That's the main reason for the voltage drop that u had... (coz i had similar problem on the passenger side light when i first installed the HID into the hella projectors e-code)

go try these first and see what happens.... if there's any further problem.. i'm here to help =)
