Might very well be interested, but I need more info...
Exactly which model Hella 4000 is it? ...One of the Rallye 4000s, I assume but which one?
If you aren't certain, can you tell me the dimensions (they range from 6+" to 9+" in dia... well, they're actually oval, but you get the point), bulb type (Xenon, Compact Xenon, Celis, etc.), and finish (chrome, matte black, or one of those wazoo colors thet offer)?
