“But hey; whatever floats your boat..”
My first was a ‘71 280SEL. Just had bulbs like a normal car. This was the entire headlight assembly. Comes as a unit with the swivel beams, LEDs, the works. Replacement was excessive, IMO. Didn’t really float my boat, but it had to be replaced.
You do what you have to do to get it roadworthy again. Did you know it was a single $2,700 unit when you bought the car? Probably not.
