Xenon lamps are a type of gas discharge lamp that produce bright, intense light. Unlike conventional halogen lamps, Xenon lamps do not use a filament to produce light, but an electric arc passing through pressurized Xenon gas. This produces a bright white light that is ideal for use in car headlights.

There are two common types of Xenon lamps: D1S and D2S. The D1S lamp is a type of single discharge Xenon lamp that is commonly used in luxury car headlights. The D2S lamp is a dual discharge Xenon lamp that is commonly used in high performance sports car headlights. Both types of Xenon bulbs are known for their durability and long lifespan, which makes them a popular choice for those looking to improve their car lighting.
