Back in the day, when your headlight burned out, you got a new one at the gas station and replaced the dud. Now, a failed headlight can crash the network that interconnects components in your car and, with “no user-serviceable parts inside” and the thing glued shut, they want you to replace the whole £1200 assembly.
Modern cars are engineering marvels. However, have we not overcomplicated everything to death. 1200 headlight is a absurd. Cars and trucks easily passing 50 grand is the result. I have a 2020 ram truck with led headlights. 1200 or so to replace a light would just make me sick.
A coworker has one of those Cadillac sports car convertibles. Not a lot of those where made. He had a fender bender and cracked the headlight. That head light was like 6000 of the expense to fix the car for crying out loud.
