Current technology is going to make even a bulb change a specialized task, with intelligent LED and Laser lighting systems that require programming after replacement, not to mention the cost of the replacement parts. Then, throw in the lane departure systems and forward vision cameras for pedestrian avoidance and night vision that require calibration anytime a body part or a front bumper is removed or adjusted, or when a windshield is replaced.
Wife's car is a 2018 BMW 540i equipped with Adaptive LED headlights. They self level depending on the load in the car, and the beams shine into the corners using the steering angle sensor for input. Replacement cost for each light, without the control unit and light module is about $3600.00. The laser light option is about $6k per light.
Easy to see why a light front end hit, enough to deploy an airbag and toast the headlights will now total the average car..............
