H7 Xenon HID bulbs

H7 Xenon HID bulbs: A bright replacement for H7 halogen bulbs

These H7 xenon HID bulbs are designed to replace H7 halogen bulbs and can be directly connected to the HID xenon ballast/starter. While they offer some advantages, there are also notable disadvantages to consider. 

Advantages:
+ More light output. HID xenon bulbs emit more light and have a higher light output in comparison with halogen bulbs.
+ Color choice, HID xenon offers a contemporary white color, like 6000k enhancing the aesthetic appeal of your headlights. But also warmer color temperatures for better visibility in bad weather.

Disadvantages:
- Light Pattern Issues: Because the higher light output, in reflector headlights, it often leads to more stray light, which can be hindering for oncoming traffic.
- ECE Approval: H7 xenon HID bulbs do not have ECE approval for use on public roads, which can be a legal concern in many regions.
- Starter/ballast is needed to power up the bulbs.

Compared with LED, an advantage is that HID xenon bulbs have a choice of color. But the disadvantages are not a direct start-up, because HID takes a few seconds to power up. And usually LED's have a longer lifespan.

Given these factors, we generally recommend using LED bulbs in Halogen headlights, especially the ECE approved ones. Unless you have a specific preference for Xenon HID technology / color of the light.
