For what its worth, if you run the headlight on main beam only (as opposed to dipped), they last 3 times as long. I have an orange lense protector fitted to my light, so I can get away with it, you may not. I have had as little as 2 weeks on the dipped before it blew. Its more a shit bulb spec than a poor light, although I have some conserns about the reflector as well. I'm converting mine to a Rally Raid UK fairing kit, so that's 1 less issue to deal with.
