What is the difference between Halogen VS Projector Headlights?

Hey manager, basically a projector headlight also has a lens that acts as a magnifying glass, increasing the brightness of the light beam.

Think you're getting confused, because you can get halogen projectors.

If the question was 'what is the difference between reflector VS projector headlgihts:' then the answer would be as follows:

Reflector lights work by bouncing light around a concave reflector.
Projector lights work by bouncing light through a 'fish bowl' type lens which focusses the beam.

Clios can come with either halogen reflectors, halogen projectors, and xenon projectors.
 
Yeah. A worthwhile mod if you want xenon’s.

Probably not too worthwhile if you don’t though.
