you could have fooled me, I thougth it was the brand new part in the box just a little dirty.

I bought new hella fogligths for my car as the old ones look milky.
MB parts number was melted ontop of the plastic housing, then foglights were sold as aftermarket parts at a fraction of stealership price.
still a genuine part manufactured for C43

I dont like waiting til the car has issues before i put in new parts

that's a very sound thinking when you know part might be very old and might break?
