Kuryakyn sells 90/100W H4 bulbs for $9, which is something any HD dealer can order. My dealer stocks them.

I used 85w100W and 90W100W on my old RK for nine years without any problems, including the last few years with a Kisan modulator. I transferred the bulb and modulator to the new SG and it still works fine. I find these bulbs lasted about three years without the Kisan modulator before the high-beam would burn out, which is the filiment used about 90% of the time on my bike. With the modulator I've had better results, primarily because the 20-100% modulation makes the bulb run cooler, according to Kisan. Based on my experience I now believe what they're saying.

I would recommend staying away from any bulb with a blue tint. The blue spectrum is less visible to our eyes, and having them tinted to a higher color temperature than the standard ~3200°K H4 is counter-productive.

I also use the Piaa anti vibration bulb. Big difference. Bob.

I have put about 7,000 miles on my Silver Stars and have not had a problem. They really light up the reflective stuff on the strpies and signs especially on brand new signs they really shine.

 

My 02 and 06 both have the same bulbs and they are plenty bright.Could yours be not adjusted correctly.Try that first.

 

Does anyone know what bulbs are in the New Dual Light Halogen Headlamp that Harley Sells?

 

I have the HID version and the high beam is an H8 35watt. Not sure what the Low beam on the non HID unt is.-- Tom
