Product Description
Shipping Information

HIDS4U now have a 55W type HID kit for H4 bulbs available called the HIDS4U Pro Max! This HID kit is the brightest Bi-Xenon conversion kit we have come across! The ballasts are rated at 55W instead of the standard 35W on other HID kits. This extra power gives an additional 100% more light than the 35W kits.

The H4 bulbs convert both the dipped and main beam headlights to Xenon light, as they use two Xenon arcs in a single bulb.

The HIDS4U Pro Max kit still only uses the same amount of power as a standard H4 halogen bulb, however the additional wattage over the 35W Pro Plus kit results in a significant increase in light. Whether you currently have standard halogens or an existing 35W HID kit in your car, the HIDS4U Pro Max kit will provide a fantastic upgrade.

These kits cannot be compared to the other HIDS kits on the market as they are all our own branded kits, which have been developed and designed by our in-house engineer working closely with the manufacturers. The Pro Max ballasts are digital (as with all our ballasts), which improves reliability and reduces the problems associated with the older design non-digital type ballasts. Due to the high quality components used in our HID conversion kits, we offer a 2 year warranty with this kit.

We have been selling HID kits for many years and we refuse to compromise on quality. Our kits have the lowest failure of any we know of with less then 1%. Our bulbs, whilst more expensive, produce more lumens and out last other cheaper bulbs.

To make fitting even easier we have written our own instruction manual so you don't have to translate the Chinese English instructions supplied with most other HID kits. We even included a fault finding guide.

This kit boasts top quality steel waterproof ballast, high quality purpose made H4 bulbs with metal or ceramic bulb holders that are designed to produce perfect beam patterns and focus just like the halogens. The bulbs have been UV cut to prevent damage to plastic lenses.

This kit is ideal for most cars even with bulb failure alarms. However please use our "Find HID Kit for my vehicle" application guide to check which of our HID kits are most suited to your vehicle.

Review: Had a minor issue with the kit, but Dean and the guys sorted it quick smart with a different wiring kit. Excellent customer service. As far as the kit goes it's the brightest set of lights I've ever seen! Very impressed.

Review: Very good improvement on dipped beam over standard bulbs. Better than other HID I've had in the past. Performance on main beam disappointing, largely due to unsuitable bulb mask provided for my car headlights. I have improved main beam performance immensely by modifying bulb mask. I am still working to improve it further.

These HID are fitted to a classic Saab 900. I may fit them on my other car when I have completed my experiments.
