HID Xenon-low beam, Halogen-high beam

The bulbs from this listing are dual beam. One bulb has HID Xenon light tube for low beam and halogen lamp for high beam. If you need both high and low beam HID Xenon light you should buy bi-xenon H4 bulbs. These bulbs are a direct replacement for your existing HID Xenon Bulbs to fit an aftermarket HID Xenon Light Conversion Kit. The H4 type HID bulbs come with wires for connection with HID ballasts. The power cables for HID ballasts are included with the bulbs. The ballasts are not included in the listing.

You can check the bulbs' type with your car manual or it is marked on the bulb itself. If you are not sure please contact us via eBay with you car make, model, version and year.

Colour / Kelvin (K) - Brightness / Lumen (lm)

In terms of brightness the higher the number of the Kelvin Temperature (K) the less light output (lumen) the bulb produce. With higher K the colour turns from stock white (4300K) to blue (12000K) and produce less lumen (lm).

If you are after the coolest looking Xenon with amazing performance then 6000K (white with just a tint of blue) is our recommendation or 8000K (white/blue light).

If you are after the most amount of light on the road then we recommend the 4300K (the brightest, OEM stock white) or 5000K (white with no blue).

10000K (aqua blue) and 12000K (violet / purple) bulbs are not road legal in the EU and recommended for off road use only.
