I went to install a new H4 headlight bulb in my K75 today. I had two bulbs on the shelf. Both were Sylvania bulbs: one titled "Basic" and one titled "Silverstar". On the package back the Silverstar said Rated Life 140 hours. The Basic bulb package said Rated Life 1110 hours. A quick look on Amazon had the Basic bulb between $8 and $10 and the Silverstar between $17 and $22.
So with my typical riding the Silverstar might last about 6,000 miles and the Basic might last about 50,000 miles. Somewhere in between Sylvania offers a bulb called "Xtravision" and then they also sell the Silverstar Ultra. I don't know the rated life of either of these bulbs.
So read the fine print and decide which bulb is right for you. Since I almost never ride at night anymore I am happy with the Basic bulb. If I were doing 24 hour endurance rallies or otherwise rode a lot at night I might go for the Silverstar or Ultra.
