• Answer:

  Different technologies: Halogen / filament bulbs: standard bulbs. You can get upgraded Xenon bulbs up to twice as bright as normal. HID: Use an electric arc. 3 times brighter than normal bulbs, and need a ballast to produce the voltage required. Factory fitted option in some cars, and available as an aftermarket conversion kit. Legality depends on where you are, but better quality kits will generally not cause too many issues, as long as the beam pattern and colour is ok. LED: Pure electronic light, available for side, indicator, stop and tail bulbs. Not especially bright, but give a very sharp, white light. Massively long life. A couple of cars use LED headlights, but they need very specific design requirements, and conversion is not possible. Projector: a type of headlight fitting that uses a lens to focus the light forward. Used with halogen and HID bulbs. Retrofit: Altering the car from factory original.
