changing bulbs on headlight

[Lumpy]

Hi Everyone
I have a 98 fazer and want to make both headlights to H4s.
How do I change the H1 fitting to H4?
I have already taken the shroud off the h1 side but want to inpove the lights.

Thanks
Kelvin

change to the 5RT fairing it's the only simplish way. The fittings for 'h4' are completely different. You may be able to sort some projector units to fit. The H4 bulbs are similar wattage and don't really shed much more, if any, light. Fit some driving lamps and maybe spots for high beams.
