I know this has come up on the forum before, but I wanted to make it more prominent.
I wanted to upgrade my headlights from sealed beams but didn't want to spend big bucks or go to LEDs. I was looking for Hellas or Cibies, but never found any that I wanted to purchase. I've had a dozen or so sealed beams that have been pierced by rocks over the years and I didn't want to get nice H4 lenses that would be destroyed almost immediately.
Anyway, I'd been looking at the Koito lenses but someone clued me in to them being offered at Toyota dealership parts departments. I bought some and I'm so glad I did.
Part number is 81110-60P70 "HEADLAMP ASSY"
This is two 7" H4 lenses from Koito with bulbs, a relay harness (not needed for the w123 application) and a bag of zip ties. And the price? I paid $44.
This is something I can drive on without worrying too much about getting a chip in the lens as I can get a new one from Toyota.
