bad for the environment...I know...but get an LED flashlight as your emergency car light and you'll at least be using the energy efficiently
I saw this on another forum and am just passing this along:
CVS, this week, has Energizer Max 8-pack of AA's, 8-pack of AAA's, 4-pack of C's, 4-pack of D's, and 2-pack of 9V's on sale for $5.29
Use attached coupon to get $5 off the purchase and get them for $0.30-$0.31 depending on the tax in your area
