This is the all new HIDS4U SLIM HID lighting kit for Motorcycles with H4 bulbs (combined main beam and dipped headlights).
These new ballasts are super thin Digital (see detailed picture below), which will improve reliability and reduces the problems associated with the older design non-digital type ballasts. These are great when space is a major premium. They are also fitted with a separate starter attached to the ballast

This quality kit allows you to convert your standard H4 halogen headlight to super performance HID Xenon. Our ballasts are E4 certified just like Hella and Philips ballasts. That's why we offer a 2 year warranty with the kits


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.

The HIDS4U SLIM ballast produces more light than other HID conversion kits and are even brighter than the factory fit Xenon headlights. Over 300% more light than your existing H4 halogen bulbs.

To make fitting even easier we have written our own instruction manual, which has recently been updated also, as the one supplied with other kits is in Chinese English and makes no sense! We even included a fault finding guide.

This kit boasts top quality aluminium waterproof ballast, high quality purpose made H4 Bi-Xenon bulbs designed to produce perfect beam patterns and focus just like the halogens. The bulbs have UV cut to prevent damage to plastic lenses

This kit is ideal for most Motorbikes (excluding those with Cam-Bus systems i.e BMW) even with bulb failure alarms. It works perfectly with the bulb alarm, without any alarms when the lights are on or off, no relays no resistors (sometimes a relay/resistor fix maybe required but this is exception not rule. Also it has a power lead plug, so you can just plug the plug on your car straight into the ballast for a perfect OEM look.
