By chance, is the white block on dash lit up? If so, means reserve lighting system has kicked in. I believe it uses an H4 size bulb.

I only understand what I don't understand.

forget silverstar and all the other nonsense, they are still a 55W/60W bulb. These are not 'legal' for on road use, but ill tell ya what my 80W/100W bulbs are brighter then all the nonsense they sell in the stores. Blue light / silverstars are not brighter, blue light just looks brighter because the eye is more sensitive to that light range from what I understand. The best light is clear white light and that is exactly what this light will do.

I have the 80/100W version on my bike and as long as the housing and wiring can handle it - its worth it

And there is the rub......... At 100W your looking at about 8A .... and that has to go through your hi/lo switch too.....

Have you checked the voltage at the headlight connector?

I have had a 80/100W in my bike since 06, no issues and 50K miles later.

I have a 800cc though, may be different then the 750's. I hope Kawasaki would use a hi lo switch that is rated more then the precise current they would be switching.

I agree that a good check is to check the voltage at the bulb. Maybe the bulb is just on its way out?

^ the 750 electrical system is weak to begin with.....

I rewired my headlight so power went straight from the battery to the headlight via a SPDT relay. The relay was energized by switching to high beam. The NC contact went to the low beam, and the NO contact went to the high beam. So even if the switch or relay failed, the low beam would always work.

Keep in mind that the power output of the bulb is dependant on the input voltage..... in other words, a 100W bulb is only 100W at a certain voltage...
Also, remember that power output is proportional exponentialy to the voltage... P=V^2/R
So a bulb rated for 100W at 14VDC, is only 73W at 12VDC....
