I have this bulb and although it's better than stock it's still pretty weak...If you want a good headlight it seems you have to go with the HID or LED.
Suck it up and get the LED headlamp. You won't regret it. WAY more light and it covers WAY more space on the road around your bike. If you're gonna keep replacing regular bulbs ...you may as well just get this one and be done with it.
ive had 5 different led ALL SUCK new set of just bulbs today oem h11 h9 is brighter and show further down the road and not blue either about to just give up at this point
