The H4 HIDCB HID conversion kit has been specifically developed to overcome the errors encountered by modern vehicles when upgrading to HID. The modern CAN-bus style systems conflict with standard or cheap HID conversion kits. This advanced HID kit has special systems built in to the ballast to allow it to integrate seamlessly without causing any bulb failure warnings.
Due to the market leading nature of these HIDCB conversion kits, 95% of vehicles do not need any additional components. For the few that do, those components are supplied free of charge complete with plug and play connectors for ease of installation.
H4 headlight bulbs have both the main beam and dipped lights in a single bulb unit. These headlight upgrades, also known as Bi-Xenon match this to allow for a simple upgrade to your standard headlights.
The HID bulbs used in the HIDCB conversion kit are accurately aligned to give optimum light output and correct beam patterns. This level of precision sets them apart from the cheap HID kit alternatives which do not give good beam patterns and cause excess glare.
All components used in the HIDCB HID kit are tested thoroughly with a very low failure rates. This allows us to offer a full 2 year warranty on both ballasts and bulbs. The high manufacturing quality of this HID kit sets it apart from the cheap alternatives and gives you a simple upgrade option and trouble free motoring...well from your lights at least!
