Last time I went to visit my grandmother, I did a quick tune-up on her 2001 Kirby Ultimate G and one of the things that I did was replace the headlight bulb. Apparently, That particular bulb only lasted one vacuuming. The bulb I installed was a type #921 automotive bulb that I have had great success with in all of my other Kirby's (Diamond Edition and Generation 3) so I don't know why her Ultimate G is eating these bulbs left and right. Any ideas would be greatly appreciated.

Hmm

If it's having issues I imagine a hot wire is hitting or a ground wire is shorting it out.
Follow wiring harness and check for anything off. I have a guy feeling the carbon brushes are screwed down and held in place. I suspect that the carbon brushes are not in securely.

You could always stick a voltmeter across the light bulb terminals (set to AC volts!) and measure the voltage.

I was thinking the same thing. I just wasn't sure everyone has this in their tool box.

Carbon Brushes

The motor runs fine and the carbon brushes have never been removed to my knowledge so I can't imagine that to be the problem.

Make sure the connections are clean too, some electrical contact cleaner spray can help. Sometimes rust or dirty connections can create a short that will fry the bulb.

Next I would try making sure you get a proper vacuum bulb, name brand, and not using car light bulbs.

An OEM Kirby headlight bulb is only 8 watts, a #921 automotive bulb is 18 watts. They cost the same price, so always use OEM parts. I am betting the bulb is being undervolted and it's the equivalent to dimming a non-dimmable bulb and it is burning through the filament, this is what kills halogen bulbs, assuming the auto bulb is a halogen one.

Correct

The carbon brushes there held in and there's also ground wires connected to them. The carbon brush has nothing to do with it. It's the wires attached to it.
Just trying to help you out.

I would not go to parts store and get a bulb. Id order a bulb from Kirby if your having issues.
