The HID55 is our high power HID kit for H4 headlights rated at 55W. The extra power means it is even more critical to ensure high quality components. Our H4 HID55 HID conversion kits are tested thoroughly in all situations to ensure the failure rate is kept very low. We are able to offer a superb 1 year warranty on both bulbs and ballasts.
The H4 HID Kits are designed for cars and other vehicles that use a single bulb for both dipped lights and main beam, and gives you a simple upgrade to high power Xenon headlights.
The HID55 HID kit has been kept simple with easy to follow plug and play connections. This allows for an easy installation. In most cases, the need for additional relay harnesses have been eliminated due to the advanced design and technology used.
The bulbs in for the HID55 HID kit are specifically designed to be used at the higher 55W power. This means the light output is optimised giving up to 400% more light on the road. As with all our kits, the bulbs are correctly aligned and provide the maximum light output, unlike the cheap alternatives.
The 55W ballasts are matched to the Xenon headlight bulbs in the HID kit, and are waterproof, vibration resistant and use the latest in digital technology. This high manufacturing quality sets them apart from the cheap alternatives and gives you trouble free motoring...well from your lights at least!
