This is a really convenient easy safety precaution you can take if you are ever stuck out on the road for a short or long amount of time. A few things I like about the Life Gear Auto Glow Rechargeable Flashlight/Emergency Flasher: Magnetic (sticks to your car if you are working on a tire or engine), re-charges from your car cigarette lighter, has 4 different light settings – flasher, glow, flashlight, glow + flashlight. It is $2.99 + shipping = $7.95 for a TWO pack! These generally retail for $7-9 each.
