OSRAM NIGHT BREAKER LASER H4 Halogen Headlight Bulbs, 12 volts, 60/55 watts, P43t, 2-pack

The OSRAM NIGHT BREAKER LASER H4 halogen headlight bulbs are engineered as direct replacements for vehicles fitted with an H4 P43t socket. Using laser ablation technology, they produce up to 150% more brightness than the minimum legal standard, resulting in a luminous flux of 1650 lumens and a beam that reaches up to 150 metres. The lamps emit a white light with a colour temperature of 3900 K, delivering up to 20% whiter light and improved contrast for night driving. They run on a standard 12 V automotive electrical system.

The dual-filament design draws 60 W per bulb, with a typical power consumption of 75 W, supporting both main and dipped beam functions from a single unit. A compact 13 mm diameter allows the bulbs to fit standard headlight housings without modification. They have an expected lifespan of approximately 400 hours, giving a predictable service interval for maintenance. The pack contains two bulbs, enabling both left and right headlamps to be replaced at the same time for even illumination.
