H1 car bulbs – how to select the correct lighting

The H1 bulb is a single-filament halogen bulb used in certain dipped-beam, main-beam or fog lamps. The H1 designation identifies a bulb family, but compatibility also depends on the lamp and vehicle manufacturers' specifications.

How to choose an H1 bulb

Check the marking on the existing bulb or in the vehicle manual. Compare the lamp holder, wattage, voltage and mounting method. Do not choose a replacement simply because it looks similar. For kits and multi-purpose products, verify exactly which bulbs are included.

Replacement and safe use

Switch off the lights and let the bulb cool before replacement. Fit it securely in the headlamp, avoid touching the glass with bare fingers if the manufacturer forbids it, and use only bulbs approved for that fitting. Afterwards, check that the lights work and adjust their alignment if required.
