This page is all about single beam H4 bulb kits - these kits are NOT the Hi/Lo ones! If you're bulbs are Hi/Lo (they have two filaments) then you need to click on our H4 Hi/Lo kits page. Most H4 bulbs in Australia are Hi/Lo, so please check first.

But if your H4 globe has a single filament (halogen) then this is the right page for you. H4 HID bulbs come in all colour temperatures (Kelvin rating) in our Supervision kits, but only 4300k or 6000k in the genuine Philips kits. The H4 bulbs will last around 3000 hours if driven by a 35 watt ballast, or around 2000 hours with a 55 watt ballast. H4 bulbs can be used on both CANBUS and NON-CANBUS cars, and are sometimes used in spotlights or driving lights.
