Halogen Headlight Bulb IWH 12V 55W P14.5s E-Certified

IWH Halogen Headlight Bulb IWH 12V 55W P14.5s E-Certified is a single-filament H1 lamp designed for standard vehicle headlight fittings. The lamp delivers a stable 12-volt, 55-watt output through a compact P14.5s base, suitable for replacing worn bulbs in compatible headlamp housings. Its design focuses on straightforward fitment and reliable light output for general road use where H1 bulbs are specified.

Advantages

The halogen construction provides consistent luminous flux and colour temperature typical for standard H1 bulbs, ensuring predictable beam pattern when installed in correctly aligned headlamp reflectors. The P14.5s base allows secure mechanical and electrical connection in compatible sockets, while the E-certification indicates compliance with applicable vehicle lighting regulations in many markets. The compact single-filament design simplifies installation and replacement in confined headlamp spaces.

How to use

Ensure the vehicle ignition is switched off and the headlight circuit is cool before beginning. Access the headlamp housing according to the vehicle manufacturer’s procedure, remove the protective cover or connector, and release the old bulb from its retaining clip or socket. Handle the replacement bulb by the base only; avoid touching the glass with bare fingers to prevent deposits that can shorten service life. Insert the IWH H1 bulb into the P14.5s socket until it seats securely, refit retaining clips and protective covers, and reconnect any electrical connectors. After installation, check beam alignment and operation to confirm correct fitment and light pattern.

Usage recommendations

Replace bulbs in pairs where possible to maintain uniform light output and colour between left and right headlamps. If beam pattern appears distorted or alignment is off after replacement, inspect the headlamp reflector and mounting for damage and adjust alignment per vehicle specifications. Dispose of used halogen bulbs according to local regulations.
