Very long shelf life from the Lithium. Won't get destroyed as much by REALLY hot temperatures inside the car in summer and will still work if it is really cold outside.
Plus, with the "twist on head" design of the Infinity, the battery isn't really engaged. Although I don't have any proof, it seems to me that batteries are way more likely to leak if they can trickle out their current. If the battery is not touching anything on at least one end (like sitting dormant in an Infinity), it seems like it will be less likely to leak (although, again, the lithium is already better at this).
The only problem is if the Infinity isn't bright enough for your needs.
If that is the case, get an Infinity anyway. It is only as big as a shotgun shell and
will work when you need it to. Just add whatever, brighter flashlight you may feel you need to it. If your kit is in the trunk, then size won't be problem. Get one of the Dorcy 4AA lights with the "poseable" handle so you can sit it in any position you want while you change a tire, whatever. They are focusable from spot to flood plus still relatively compact.
Dorcy Mini-spot 4AA flashlight
Walmart sells these for the amazing price of $3.29!
If you want, add 4 more Lithiums and leave them in their blister pack until they are needed; include a spare bulb. You'll have the Infinity handy in the glove box at all times, just reach, twist and you've got light! Then you can assemble your (really, whatever you want) ultimate, bright light in the comfort of your car; no leakage, no filling up the glove box with a bunch of bulky 'packages'.
