## Long description

Osram Night Breaker Laser H4 75 W 12 V P43t halogen headlight bulbs, pack of 2, are designed for vehicles that require H4 twin-filament bulbs for both low and high beam functions. These bulbs provide a standard halogen light source with a 75 W power rating and a P43t base, compatible with H4 sockets in many passenger cars. Supplied as a twin pack, they serve as direct replacements for worn or damaged headlight lamps where a 75 W H4 bulb is specified.
Advantages
The Night Breaker Laser H4 bulbs deliver consistent halogen illumination with reliable electrical and mechanical compatibility for vehicles that use H4/P43t fittings. Their 75 W power rating offers increased luminous output compared with lower-wattage halogen variants, maintaining stable beam pattern and good road visibility under typical driving conditions. The twin-pack format ensures both headlight bulbs can be replaced at the same time, helping to preserve balanced light output and colour temperature between left and right lamps.
Suitable for
Replacement of H4/P43t low/high beam bulbs in passenger cars that accept 75 W rating
Drivers seeking a straightforward halogen swap without electrical modifications
Maintenance or repair where both bulbs are replaced simultaneously
Key specifications
Type: Halogen H4 twin-filament headlight bulb
Power: 75 W (per bulb)
Voltage: 12 V
Base/fitting: P43t (H4 compatible)
Pack quantity: 2 bulbs
Intended use: Vehicle low beam and high beam applications
How to use
Before installation, ensure the vehicle ignition is off and the headlight switch is in the off position. Allow the existing lamp assembly to cool if recently used. Access the headlight housing according to the vehicle manufacturer’s instructions, remove the old H4 bulb by disconnecting the wiring connector and releasing any retaining clips or caps, and then fit the new Osram Night Breaker Laser H4 bulb into the socket, making sure not to touch the glass with bare fingers. Reconnect the wiring, secure the bulb retaining features, and test both low and high beam functions. If needed, adjust headlight aim following vehicle guidelines to ensure correct beam alignment.
Usage recommendations
Replace bulbs in pairs to maintain uniform light output and colour between both headlights. Avoid direct contact with the glass envelope; use clean gloves or a lint-free cloth during handling. Verify compatibility with vehicle electrical and lighting regulations before fitting 75 W bulbs, and consult a qualified technician if modifications or relays are required for higher-wattage installations.
