H1 halogen bulb for the 24 V electrical systems of trucks, buses and agricultural machinery.
The AUTO PRACTIC H1 car bulb runs on 24 V and delivers 70 W from a single H1 filament, matching the electrical systems of trucks, buses and heavy machinery. It is supplied singly, ideal as a spare in the cab or as a direct one-for-one replacement.
H1 base for single-filament headlamp units
The bulb fits standard H1 sockets used for low or high beam, halogen fog lamps and auxiliary driving lights. Check the marking on the bulb you are replacing so the base matches.
24 V version for trucks and buses
The operating voltage matches the on-board systems of heavy-duty and farm vehicles. Passenger cars with a 12 V system require the 12 V version of the same base.
Fitting without touching the glass
Handle the bulb by its metal base during fitting — grease from fingers on the quartz glass shortens its life. Replacing both sides of the headlamp at once keeps the light output even.
