Xenon lights, also known as high-intensity discharge (HID) lights, produce a brighter light than halogen bulbs and with far less heat. The blue-white light emitted by xenon bulbs is so bright, it has been known to “blind” other drivers.
These headlights require a large amount of power at the outset to produce their first burst of light, but once fully operational, they require much less energy to maintain constant brightness.
Xenon bulbs have a long lifespan and emit little heat, but they cost more than halogen bulbs.
Here are some ideas on how to identify the model of HID:
