H4 halogen bulb combining low and high beam in a single unit.
The NARVA H4 12V 60/55W car bulb is a halogen headlight bulb for 12 V cars and motorcycles with an H4 (P43t) base. Two filaments inside the single bulb serve both low and high beam. Supplied as a single piece.
H4 (P43t) base for combined low and high beam headlamps
The bulb fits any headlamp designed for the H4 standard on a 12 V system — the most widespread type on cars, vans and motorcycles of earlier generations. The three-tab base locks the filament in the exact position the reflector was designed around.
60/55 W — the standard halogen output for H4
High beam draws 60 W and low beam 55 W — the factory rating for road-legal H4 headlamps, so wiring and relays stay within their design load. It is a direct swap with no adapters or resistors.
Single-piece pack for replacing a burnt-out bulb
The pack holds one bulb — handy when only one side has failed or when topping up the spare in the boot. Handle it by the base only; fingerprints on the quartz glass shorten its life.
