Can the fog light glass be taken off to clean inside?

Not on any of the ones I've seen. To my knowledge they are sealed units.

I don't believe so either. The lens is molded or pressed onto the fog light housing. My lenses are all plastic, yours should be too I'd imagine. Many members here convert to Cyberwhites, or Angel eyes for fog lights.

and worth the $$ in upgrading mainly because of the better light output

Is one better than the other for light output? I like the looks of the Angel Eyes, but I would like them to be effective when I turn them on

the Angel Eyes have alot of High Output, i think that they are personally better than the Cyberwhites... I think that the AE'* have the high output that shoots higher than the Cybers.....i personally perfer the AE'*....i also have H3 silverstars in the AE'*

Let me say this..both are good lights and put out about the same amount of light.

Which explains why I put a set of angels on my car and then have a brand new set of cyberwhites sitting on my floor for sale. (litterally in the box)

Also the Hellas have the "Angel Eye" rings if your in to that thing.....they are really sweet when you get them on the car......not to be out done the some of the Cyberwhites have a small bulb that illuminates the inside of the lense too

Not all Cybers have the bulb. My set does, but there are many different versions of the same light.

that is true....there is a blue lens set that have the little bulb in them, and there is also a white lens set that does not have the bulb
