High Power H4 LED Headlight Bulb Kit

This listing is for a PAIR of Halogen H4 LED bulbs complete with control circuits.

The H4 bulb has double filaments inside the lamp and produces light for the MAIN and DIPPED beam headlamp functions.

These are the latest generation of LED headlight bulbs that use the Philips "LumiLED" led chips. These LED's are very bright and very small meaning they can give a light output very similar to the original H4 bulb giving a very controlled beam pattern.

Although not clear from the pictures there are 8 LED's on each side of the bulb - so 16 LED per bulb.

8 of these are used for DIPPED beam and the other 8 are used for MAIN beam.

This gives 25W ( electrical power consumed ) and 4000 lumens ( light output ) on main beam.

The light output in lumens from a standard H4 bulb is 1000 -1400 so these are roughly 3 times brighter for half the electrical power consumed. The colour temperature for these bulbs are 6500 kelvin.

Currently the dipped beam does not stay on with the main beam but we are working on this upgrade and it is in testing at the moment.

No changes to wiring are needed to fit these bulbs - they plug and play to the current wiring.

These bulbs are intended for off road and show use only - see below extract from recent VOSA guidance for MOT test stations ( for road use we recommend our full LED headlights - see our other items )

"Headlamp washing and levelling systems are mandatory for all vehicles fitted with LED headlamp systems, although these are not yet widely used and only tend to be optional fitment on some executive marques."

These bulbs can be used for RHD ( UK, japan etc ) and LHD ( USA, France etc ) cars as it is the headlamp reflector shape ( not the bulb ) that sets the beam pattern.

Fitting Details

Remove the rubber cap from the back of the headlight and then remove the 3 way electrical connector.

The bulb is held in place with a wire clip - release the clip and the bulb can then be removed.

The front plate on the bulb can be adjusted to achieve optimum beam pattern - see video.
