Here’s a question worth asking the next time a shop quotes you four figures for a headlight replacement: why can’t you just fix the part that’s actually broken? In most modern vehicles, the answer comes down to a tube of adhesive. Headlight assemblies are glued shut at the factory, which means a cracked lens or a failed seal condemns the entire unit — a wasteful outcome that costs owners real money and sends perfectly serviceable hardware to the landfill. Mercedes-Benz has decided that’s no longer acceptable, and it’s doing something about it.
