Halogen Bulbs
Halogen Headlight Bulbs
Halogen bulbs are the standard fit for headlights, high beams, fog lights and driving lights on most vehicles. Each type, such as H4 or H7, has its own base and is made for a particular kind of light. We stock these in 12V, with 24V versions of several types for trucks and machinery.
Which bulb do I need?
The type is usually marked on the base of the old bulb. Pick it below to see the bulbs we stock.

This is a general guide, and some vehicles use different bulbs. Check your old bulb or owner's manual, or ask us. Stop, tail and indicator bulbs are on our Bayonet Bulbs and Wedge Bulbs pages.
How do I find out which bulb my vehicle uses?
Look on the base of the old bulb, or check the owner's manual. Many vehicles use different bulbs for high beam, low beam and fog lights, so check the one you are replacing. If you're still not sure, give us the vehicle details and which light it is.
What is the difference between H4 and H7?
An H4 has two filaments, so one bulb does both high and low beam. An H7 has one filament and does one job, so the vehicle has a separate bulb for the other beam. The bases are different and they can't be swapped.
Are H8, H9 and H11 interchangeable?
No. They look alike, but the bases are shaped differently and the wattages aren't the same. Always use the type your light was made for, as the wrong bulb can overheat the wiring or give a poor beam.
Should I replace headlight bulbs in pairs?
It's a good idea. Both bulbs have usually done the same hours, so the other one is often not far behind, and a new pair gives you an even light on both sides.
Why shouldn't I touch the glass?
Oil from your skin creates a hot spot on the glass, which can shorten the life of the bulb. Hold it by the base. If you do touch the glass, wipe it clean with methylated spirits before fitting it.
Can I fit a higher wattage bulb?
Higher wattage bulbs, such as 100/90W, draw more current and run hotter, so they can damage standard wiring, switches and headlight lenses. Many are sold for off-road use only. Check the pack before you buy, or ask us what suits your vehicle.
Do I need a 12V or 24V bulb?
Most cars and utes are 12V, while many trucks and some machinery are 24V. The voltage is usually marked on the old bulb. A 12V bulb will fail straight away on a 24V system.
