Greetings. I've got a one-eyed 1989 GL-10 wagon and I'm trying to replace

the halogen bulb on the bad headlight. The bulb is secured to the back of

the assembly with a yellow plastic locking ring. Whoever fastened it last

(before I got the car a decade ago) over-tightened it, and I'll be danged

if I can't remove it without breaking something.

 

Might someone have an idea of what type of tool would be best for loosening

this plastic collar? Adjustable pliers aren't big enough to go around the collar

and would strip the teeth on its exterior. Tried using my belt but that didn't

work. It's on too tight.

hi, slip joint pliers but if you break it the rings are not hard to get another one, unplug the wire connector first , that gives a bit easier access to it, spray water on it to act as a lube might help.

Rubber strap wrench. Also works well to remove oil filters
