H7 HID Kit (35W-55W)

$59.99 - $129.99

H7 HID Kit by HIDextra.

HIDextra's H7 HID Kit consistently outperforms the competition. We are able to achieve this by refining our HID bulb designs and focusing on building the longest lasting headlight conversion kits. Our exclusive C-Ring® light center technology ensures that our bulbs generate optimal beam patterns and spread without any compromises. Our bulbs are powered by a set of Neptune-Core® ballasts chipsets engineered to produce the highest lumens output per wattage - meaning more light with less power used.

What's Included:

Our conversion kit will include; two H7 HID bulbs, two ballasts (Signature Series, Stealth Series, Power Series or Pro Canbus Series), wiring accessories, and mounting accessories.

Do I Need a Relay Harness?

If the vehicle has automatic or daytime running lights a relay harness is recommended because it helps resolve potential flickering issues or lights not turning on when connected to the HID kit. The relay harness will help regulate the power by pulling power directly from the battery and keeps the lights running reliably.

Do I Need a Capacitor?

Vehicle makes that require capacitors are Audi, BMW, Chrysler, Dodge, Jeep, Mercedes, Volvo, and Volkswagen. It is generally recommended for all luxury and European makes and any vehicle that newer than model year 2006. This accessory removes the dash warning lights as well as headlight flickering warning. Our PRO Canbus Series ballasts have built in capacitors, so they do not need to be purchased if you select this ballast series.

Color Temperature?

The most popular would have to be our 5000k which produces a pure white light while the 6000k produces a white light with a hint of blue.


35W or 55W?

HIDextra HID Bulbs and Ballasts are made with OEM grade components and do not produce more heat than factory halogen bulbs. We can ensure you that the 55W HID Kits will produce 30-40% brighter output when comparing with our 35W HID kits. Both the Power and PRO Canbus Series are specifically designed to generate less heat than traditional 55W headlight systems, making them compatible with all vehicle’s high and low beams.
