i agree 100% on new technology costs on cars is getting crazy.
i forgot to add that the headlight main beam also turns with the steering wheel also. they also rise and lower the headlight aim by themselves when the load changes the car height. also when replacing they have to be programed also. sometimes they won't even light up until they have been programed. i think the HID bulbs are in excess of $100. when aiming these lamps you need a scanner to do that, no hand tools are required.

i recently repaired a high end BMW with similar priced headlamps.

Mazda also has similar headlamps i their high end cars. some cost in excess of $3K EACH.
i would assume that all car and truck manufacturers have expensive parts like this in their cars.
