OSRAM ULTRA LIFE 64193 ULT - Long-life H4 12V 60/55W halogen bulbs (Pack of 2)
The OSRAM ULTRA LIFE 64193 ULT are H4 halogen bulbs with a P43t base, designed for headlights with both low and high beams in a single bulb. They offer a color temperature of 3200 K and a luminous flux of 1650/1000 lm (high/low beam), meeting ECE H4 homologation standards. They are notable for their long lifespan compared to standard halogen bulbs, reducing downtime and maintenance costs, especially in vehicles driven daily or equipped with daytime running lights (DRL). This item is supplied in a pack of 2 .
The power measured at test voltage ( 13.2 V ) is 75/68 W (max.), while the nominal power is 60/55 W according to category H4. The standard dimensions ( 82.0 × 17.0 mm ) and approximate weight ( 25.90 g ) ensure plug-and-play replacement in H4 bulb holders. The design with a silver cap is optimized for clear glass headlights.

Frequently Asked Questions
Is it compatible with my car?
Please confirm that your headlight uses H4 (P43t) 12V . If your vehicle uses H1, H7 or another type, it is not compatible.
Why are there two values for power/flow and life?
The H4 integrates two filaments (high/low beam). That's why pairs of values are indicated (75/68 W, 1650/1000 lm, B3 and Tc per filament).
Does it work for headlights with clear lenses?
Yes. The design with a silver cap is intended to be integrated into clear glass optics.
Do I need special tools to assemble it?
No. It's a plug & play replacement; avoid touching the bulb with your fingers and check the beam adjustment after installation.
Installation Notes
- Do not touch the glass with your hand; use gloves or a clean cloth.
- Check the condition of the bulb holder and the on-board voltage.
- Check the headlight alignment to avoid glare.
