I would like to show you what’s different between halogen headlights and projector headlights as below.

Halogen headlight consists of a bulb encased in a steel reflector bowl.

Projector headlights are similar to reflector headlights. They contain a bulb in a steel bowl with mirrors to act as reflectors. However, a projector headlight also has a lens that acts as a magnifying glass, increasing the brightness of the light beam.

Halogen headlights are cheap and easy to be installed.

Projector headlights are brighter and less blind to other drivers.
