if you look at the link i sent, every electronic part in the headlight is individually replacable. the whole headlight unit is just the plastic shell (the most expensive part) bulbs, a few servos, a ballast, and an adaptive control unit.

both sides being out tells me there's something else going on here-- can you confirm with a multimeter that you are getting power to the control units?
