I've got the washers on my lights. They're not hooked up though. I learned that they're actually hydraulically lifted.
It's just an extra piece to polish now. I wish they made a xenon version without the washer. Litronics have washers, halogens don't.
Another fun fact:
N/A 996 headlights have
ridges in the chrome area
Turbo headlights are
smooth like a mirror.
