10 months ago when I go my new VN900 I changed the headlamp bulb for one of the new Philips Motovision bulbs. Motorcycle Dealers In The UK. At about £14 not cheap and I cant say I was that impressed. Last night whilst riding home at midnight (when else) the low beam failed. I try to use my bike every day so I don't know if this is a reasonable life or not. On my previous bike I fitted a PIAA anti vibration bulb, at £38 very expensive and once again I was not that impressed PIAA POWERSPORT BULBS. So what to use this time, well I did some hunting around on the net and found that some bikers had used these to good effect. Phillips extreme power, said by one car magazine to be the best accessory invented for the car. As you can see by the link I found a site selling them in packs of two for a very good price £19.99. Philips X-Treme Power H4 from Car Bulbs Direct | Free Worldwide Shipping. I have ordered some so will see what happens.
