I have a 2010 SG and a 2009 Low Rider that I believe both take a H4 bulb. I was looking at Biker Hiway website and found this:
PIAA H4 Super Plasma GT-X Anti-Vibration Twin Beam Headlight Bulb

It puts out 135/125watt but only draws what a 60/55 watt bulb does. Has anyone tried one of these. I know that they are not legal for street use but since it is only a single headlight I dont think anyone would bother me. My concern is it worth changing out the bulbs and will it give me improved lighting?

Thanks

Typically, the anti vibration bulbs run lower wattage. The PIAA claims are not completely true.....how do you get 100+ watts of light with 55 watts?
They color the light, which further reduces the output, BUT>>>
the light may be a color temperature that helps oncoming drivers to see you, but won't put more light out in front....a reflector change is suggested, or at least a bulb with more wattage.....get 2 ..they burn out quicker.
Maybe try a 75/90....or a 75/100.

High Wattage bulbs

If you change to higher wattage bulbs, I would strongly recommend using a relay in the circuit to take the heat away from the stock wiring. It is not designed for more than the stock wattage bulb. I found that out the hard way. The result is melted wires and (unless you get lucky) a burning hulk on the side of the road.
