Frequently Asked Questions

What is the difference between the 55W and 100W H3 bulbs?

The main difference is their power rating and electrical demand. The 55W version is intended for standard H3 applications, while the 100W version provides higher output for compatible competition and off-road lighting installations.

Are these bulbs suitable for WESEM rally lamps?

Yes, provided the selected bulb wattage is compatible with the particular WESEM lamp unit. Always check the lamp's specified maximum bulb rating before purchasing.

Can I use a 100W bulb in a lamp designed for 55W?

No. You should not exceed the manufacturer's specified bulb rating. The additional heat and electrical load can damage the lamp housing, wiring, connectors or reflector.

Are the 55W bulbs road legal?

A 55W rating alone does not guarantee road legality. The bulb and complete lighting assembly must meet the applicable road-use approval requirements.

Can I use the 100W bulbs on public roads?

The 100W version is intended for off-road, rally, track and competition applications. It should not be used on public roads unless the complete installation is specifically approved for that purpose.

Are these bulbs sold individually?

Yes. Each purchase includes one H3 halogen bulb in your selected wattage.

Do I need to modify my existing lamp to fit these bulbs?

The bulbs use a standard H3 fitting. However, you must ensure your existing lamp is designed for the selected wattage and that the electrical system can safely support it.

Important Information

The 100W H3 bulb produces additional heat and draws more electrical current than the 55W version. Check compatibility with your lamp housing, wiring, connectors and vehicle electrical system before installation.

Always use the correct bulb rating specified by the lamp manufacturer.
