Hi quaileggs,no its just an 18650 cell fed light.

If you want a good all round light for car on AAAs then i love my lenser t7.2
It eats 4xAAA cells,lenser recommend using alki but lots have had issue free use from nimh so if its to be stored in car i would feed it 4xAAA eneloop cells,these hold charge for a long time and wont leak.
Burst iirc is 320lm,high is 250lm and low is 40lm. Now its not a regulated light,but i find it quite efficient all the same,it gradually gets dimmer,bonus of this is it doesn't drain cells as quick,also no surprise turning off as plenty of warning to replace or recharge cells as once it gets to say 80-100lm then you know time to change/charge cells.
I get many hours of usable light,the flood is very handy and the throw is more than adequate for most needs.........also the t7.2 can be locked,twist of head and can lock in what ever part of the zoom your in.
Just an option,its a good light imho
Other than that there are lights like the sunwayman d40a that runs on 4xAA cells,also nitecore ea4 again 4xAA cells(the newer button does not have the issues of the 1st version where reports of button ballooning.
Bigger still,i like the nitecore ea8,this believe or not eats 8xAA cells,bigger light,bigger 60mm head.Also fenix tk41 and tk45 on AA cells if a preferred choice but as with the ea8 they are a larger light,bonus of 8 cells on lower modes is longer run times in emergencies........
For all the above i recommend eneloop cells,they are 1 of the best nimh rechargeable cells on the market imo,up to 1800 charge cycles and retain 75% charge after 5yrs.........apparently :laughing: i have not got the time to check or memory for that matter :laughing: Leaving alki cells of any kind in lights unused(even used) poses a risk of them leaking and ruining your nice new light.If it is a way you go make sure they are changed regular and not left for years......
:thumbsup:
