I agree..not worth waiting for, especially if you have to get the damn TPS with them..
On my oil cooler, I was getting about the same before swapping the HIDs, but I was never happy with those so I won't do that again.
The thing that kills those bulbs is the constant dimming and brightening (is that a word?) the system does every time the bike idles or revs. The new bike does not do this at all. I do a bunch of night riding and I've never noticed the lights dim even a little. This more constant output should keep the bulb alive longer.
