Frequently asked questions

What is an H4 bulb used for?
An H4 bulb is a dual-filament halogen headlamp bulb built to the H4 standard with a P43t base. It carries both the main-beam and dip-beam filaments in one capsule, for headlamp units that take an H4 bulb. This Osram bulb is supplied singly.
How many H4 bulbs should I replace at once?
H4 headlamp bulbs are typically changed in pairs so both headlamps match in brightness and beam colour, though this one is sold singly. When one filament fails the other bulb is usually near the end of its life too, so fitting two keeps the pair even.
How do I confirm my headlamp takes an H4 bulb?
Check the old bulb base: an H4 has three connector tabs and a P43t base, with two filaments visible for main and dip beam. That distinguishes it from single-filament H3 or H7 types. The headlamp or capsule is usually stamped H4, so match the exact type before ordering.
