Any decent light that takes ’123s would be perfect. Eg, a SP32Av2 that takes a pair, Jet-II which takes one. Consider stick-on diffusion film, because when changing a tire, you don’t want a narrow bright hotspot, ’cause then it’d be like using a laser-pointer for illumination.
NiMH is also a good choice, as eneloops are low self-discharge, so a 2×AA light (SF13?) would work nicely, too.
A headlamp is almost a must-have item, too. Again, diffusion film in case the hotspot is too narrow. Don’t have any myself, but I think Skilhunt is highly-rated for AA-based headlamps.
’Though one thing to consider would be something like a stick-on worklight, like a (Nitefox) UW360. They’re 18650-based, so I wouldn’t necessarily keep it in a glovebox with in-car temperature extremes, but it’s a good carry-with light anyway. [review] Nitefox UW360
