I bought several AA lights for cars, EDC, etc over the last several years. My favorite is a Fenix LD22 for AAx2 and it’s my current EDC. I like the ease with which you can switch between low, mid, high and turbo modes with the side switch.
I also picked up a Streamlight ProTac 1L 1AA Dual Fuel light which is awesome in that it can use either AA (any type) or CR123 lithium primaries. It’s very bright but not as easy to switch to other levels/modes so it just stays in the GHB loaded with a 123. It’s a great backup light.
One of the attractions to AA lights is that you can pickup alkalines anywhere, but seriously, I cannot recommend highly enough that you consider buying eneloops to actually keep in the light. Alkalines can leak without warning and do a lot of corrosive damage quickly. Eneloops are the bomb!
