Presumably you mean the headlamp bulb, Markopolo. I plumped for an Osram Nightbreaker upgrade to the main lamp on my Honda - much brighter than the standard H4, much cheaper than an LED installation / conversion, with the only drawback being slightly shorter service life. But it transformed the forward lighting. Then again, I have twin CREE 10 watt LED spots on the crash-bars, cheapo Chinky ones, to make a triangle of light which makes me much more visible to oncoming dopey cagers who're busy texting their mum / applying their lipstick / doing their hair / chastising the kid in the back seat, etc., etc..
