Getting a headlight loose

[BigV]

good points hagar:

SD, I urge you to examine the other side that came off easily. Is it merely threaded all the way to the base? Or does it have a little lug that needs to fit into a slot, indicating the need to press ... inward to release, then unscrew. I recently made the same change and I didn't have the sticky collar problem you're talking about, but the idea of removing the plug first is golden--space is tight enough in there already. Also bonus points for the glove tip.

Tool of choice in my situation: Channel-Locks. Long lever for, well, leverage. Parallel jaws to grip the ring, and they can be neatly adjusted to the size of your collar and the size of your hand/grip. Maybe you even need to go an buy a new set to do the job. Now that would be a double win!
