Headlight buying guide
Why replace this part?
Headlight units house bulbs, reflectors, and lenses that provide legally required forward illumination. Cracked, moisture-filled, or severely fogged lenses reduce light output significantly and are an MOT failure item.
Signs you need a replacement
- Cracks, chips, or moisture ingress in the lens
- severely yellowed or cloudy plastic
- internal reflector damage
- headlight aimed incorrectly after impact
- complete electrical failure of the unit
When to replace
No fixed interval — replace when the housing is damaged. Polish yellowed lenses as a temporary measure; full unit replacement is the long-term fix.

What tools do I need to replace a Headlight?
Tools needed: T20/T25 Torx or 8mm socket (varies by model), new bulb (handle only by the base -- finger grease on the glass shortens halogen bulb life significantly), beam alignment screwdriver.

Xenon/HID ballast units carry lethal voltages even after disconnection from the vehicle.
