Here is a slideshow I made a few years back when installing the GW headlight upgrade kit. �Near the end is a look at the bulbs and the retaining rings. �Hope this helps. �Thanks!

Incidentally, I have had several of the plastic headlight adjusters break on me. �Replaced some with new from vendors, but lately just cobble up homebrewed fixes out of fuel line scraps, washers, moly toggle bolts and E-clips from the hardware store.�

There is no need to disturb the adjusters when removing/replacing a bulb.
Just remove the four screws holding the assembly in place.
� Then support it while you loosen the connectors to both lights.� The
connectors may be stiff and sticky.� If you are only replacing the bulb for
the low beam, you can leave the high beam connected and hold the assembly
up while you deal with it.
