How to use

Turn off the vehicle and allow the existing lamp to cool before starting. Access the headlight housing according to the vehicle manufacturer’s instructions, remove the protective cover or connector, and disconnect the wiring plug. Release the retaining clip or mechanism and remove the old bulb by pulling it straight out. Handle the new IWH H4 bulb by the base only; avoid touching the glass envelope with bare fingers to prevent premature failure. Insert the bulb into the socket ensuring correct orientation and secure the retaining clip. Reconnect the wiring, replace any covers, and test both low and high beam functions before closing the hood.

Recommendations

For reliable performance, replace bulbs in pairs to maintain balanced illumination. If replacing a bulb after touching the glass, clean the surface with isopropyl alcohol and a lint-free cloth. Use the IWH H4 bulb only in compatible H4/P43t fittings and follow vehicle-specific guidance for access, alignment, and beam adjustment to ensure road-legal beam pattern and optimal visibility.
