Yamaha Is this normal for a lightbulb?

[insertusernamehere]

Sorry if this is in the wrong place. The headlamp is burned out, but the filament is sticking to the side of the glass, as if it popped or something. I thought that when a light bulb burns out, the filament just breaks? The reason I ask is because I've heard of voltage problems with the headlights on the YFZ450's, where it will give the bulb too much power and the bulb will pop. So I would like to know if this is normal or not for the bulb to do this when it burns out before I buy new bulbs and possibly waste them. Also, they were like this when I bought the quad and I never bothered replacing them, so I don't know if there was an audible pop or not.
