Being able to see what you're working on is the second most difficult part about being a DIY mechanic (crawling into a semi-comfortable spot under the hood is No. 1). Having a light source that is both reliable and convenient is invaluable.
Snap-on's rechargeable Xenon flashlight (stock # CTL4918) is the latest addition to our tool forage. It slips onto any Snap-on 14.4- or 18-volt battery pack (we also have the 14.4-volt impact gun, so things are even more convenient). The flashlight is available with or without the battery packs and charger and there's also an LED version available. Check it out at www.snapon.com.
