ALCA H4 Car Bulb 12V 60/55W, 1 piece

H4 halogen bulb covering both low and high beam from a single socket.

The ALCA H4 car bulb (12 V, 60/55 W) is a replacement halogen headlight bulb with an H4 base, combining high beam and low beam filaments in one unit. Supplied as a single piece, it is the straightforward choice for a burnt-out bulb or a spare in the boot.

H4 base for dual-filament headlights

The bulb fits any headlight designed for the H4 standard, the most widely used format on cars that combine low and high beam in one unit. Check the marking on the old bulb or the vehicle manual before buying.

12 V for standard car electrical systems

The operating voltage matches the electrical system of passenger cars and light vans. The 60/55 W rating is the H4 standard, so no wiring or relay changes are needed.

Fitting without touching the glass

Handle the bulb by its metal base only — grease from fingers on the quartz glass shortens its service life. Replacing both headlight bulbs at the same time keeps the light output even on each side.
