How to use

Ensure the vehicle ignition is off and the headlight switch is in the off position before starting. Access the headlamp assembly from the engine bay or behind the headlight according to the vehicle manual. Remove the headlight cover and disconnect the wiring connector, then unclip or unscrew the bulb retaining mechanism. Carefully remove the old bulb by its base without touching the glass surface, and insert the new Osram Classic H4 into the socket, securing the retaining clip or screws. Reconnect the wiring, replace any covers, and test both low and high beam functions. If unsure about access or fitment, consult the vehicle handbook or a qualified technician.

Usage recommendations

Do not touch the glass envelope with bare hands; oils from skin can shorten bulb life. Replace bulbs in pairs when one side fails to maintain balanced illumination. Verify lamp alignment after replacement to ensure proper beam pattern and legal compliance.
