The UNITEC H7 car bulb is a 12 V / 55 W halogen lamp with a PX26D base — the standard fitment for low and high beam headlights on most cars using a separate H7 reflector. It is supplied singly, one bulb per pack, as a replacement or a spare to keep in the car.

PX26D base for direct headlight replacement

Filament positioning follows the H7 standard, so the beam pattern stays within the geometry designed into the headlight. Fitting needs no tools — the bulb is held by the housing's retaining clip.
