OSRAM Original Line H4 Halogen Headlight Bulb (64193A)

Description

Genuine OSRAM · Part no. 64193A

OSRAM's 64193A is the Original Line H4, a standard-brightness 12V halogen headlamp bulb rated 60/55W on the P43t cap, known in the trade as the 472. It is OSRAM's like-for-like replacement for the H4 a car was built with, approved under ECE R37 and sold in a single box.

Good to know

• Is H4 the right bulb for my car? The bulb's number (H4, H7, 501, 382 and so on) is in the car handbook and is usually printed on the base of the old bulb; the new one must carry the same number. Look for H4 or 472 and the P43t flange on the old one.
• Why does one bulb do dipped and main beam? An H4 bulb has two filaments in one glass, one for dipped beam and one for main beam. In an H4 rated 60/55W, the 60W filament is main beam and the 55W filament dipped beam.
• How do I fit it without shortening its life? Halogen bulbs should not be touched on the glass with bare fingers, because skin oil left on the glass shortens their life. Hold it by the metal base, and do the other side at the same time so both beams match.

Which one?

For longer life in the same H4 holder there is the OSRAM Ultra LIFE 64193ULT; for off-road work lamps the OSRAM Super Bright 62204SBP (100/90W) is in the range too.
