It seems as if there's a problem with OE Euros as they age. I've seen quite a few posts lately about it, the reflectors get corrosion, and don't reflect light as well as they should. I know they're old parts and old parts aren't always expected to be right some 20 odd years later, and I know of a fix, but I want to see how many users with used, Hella or Bosch Euros have experienced this.
