H4 bulbs
These 2-filament bulbs with P43t base are for high/low beam headlamps and Cibié BiOscar fog/drive beam lamps. Fun facts: The H4 was the world's first 2-filament halogen automotive bulb. It was introduced in Europe in 1971, and was used in many millions of European and Japanese headlamps starting in that year, but wasn't legalized in the US (where it was designated HB2 or 9003) until over two decades later, in 1992!
