I have one set of spares for the backup lights, although I don't think that two would be excessive. They slide down and out of the way until you break one. This happened to me recently- at first I was a bit shocked that it broke while gearing up, and then I was very satisfied that I had a spare that I could just slide up and use!mwhities:hehe I'm not going to let some redoing of the harness stop me. I was just being a butt head. I do need to add that. I read somewhere on SB that someone did that because they kept breaking them. How many should I add to each side?

It looks like you have an inner tube for the inflator too- it wouldn't hurt to have a backup there as well. If you change to a different method, you could always cut it off if it was unnecessary.
I just blew out a bike tire, so let me know if you need some.
