Right... I'm a total novice when it comes to bulbs so I need some help.

I need to replace main high/low beam bulb, and I've been told that the BA's use the folllowing bulb for this: 55/60 watt H4.

I've got a pair of H4 Halogen bulbs that are rated as 100/90 watt and I'm wondering are these ok to use?

can someone explain how these differ from 55/60 watt?

does it refer to power required, or light emmitted?

like I say guys... I'm a novice with these so any info would be appreciated.

thanks

the 100/90 is the wattage of hi to low so they will be a whole lot brighter than the standard bulbs - oncoming motorists will hate you I went with the 50% brighter bulbs ya can buy (still 55/60) and I get flashed all the time

thanks Ace.

much appreciated mate,

cheers,

90/100's will melt you wiring and reflectors in you headlights. You would need to install a relay for hi, a relay for low and possibly a change over relay. you would need to tak a fused power feed from the battery to supply the globes,

FYI 55/60's on high will draw aprox 19amps 90/100's will draw aprox 31amps. A substancail increase.....

thanks hiddeous forgot to mention that part

My brother had an engine bay fire from the 90/130 globes in his mazda 323.

The wires melted and shorted out causing the airbox to catch fire.

Just replace the stock globes with the Phillips +50%, as they are a much better globe.

thanks guys...

think I'll get some 55/60's instead.
