What are the differences between halogen, xenon, and LED lights?

[VincentMarie]

Halogen, xenon, and LED lights differ in their working principles: Halogen lights work by passing an electric current through a tungsten filament, heating it to incandescence to produce light, converting electrical energy into thermal energy and then into light energy; Xenon lights operate by using a high-voltage current to activate xenon gas, creating an arc of light that continuously discharges between two electrodes; LED lights function by directly converting electrical energy into light energy through an LED chip. Car headlights, which are the front lights of a vehicle, provide illumination for safe driving at night. When the brightness of car headlights is insufficient, a headlight booster can be used to supply a constant working voltage to the vehicle's front lights.
