Everyone, the off-shore Euro light copies by companies like TYC, Depo, etc are ok quality but they're not as nice as the real Bosch or Hella lights. Most places want $400-$500 for a set of real Bosch or Hellas, which makes the copies look cheap. However, PUMA (
www.puma-access.com) sells the real Hella lights at great prices. I know they can get 124, 126, and 201 chassis lights... but I'm not sure about 123's. Their prices on the 124 lights are fantastic. Give them a call and ask to speak with Paul, he's the Mercedes expert there.
Note: The eBay Lucids are probably a great deal if they sell for under $200... can't beat that price. Another alternative for W123's is to just get the round 7-inch Hella E-codes, they don't look as snazzy as the "one-piece" Euro lights but they work fantastic. Cost is roughly $75/pair from
www.rallylights.com, or Paul at PUMA carries them to (not sure on the price though). They are listed as "off road only" but just ignore that silliness.
