4. Cyalume Industrial Grade Light Sticks ($13)

If you need to fix a flat or make a repair at night, then you need some type of light source. The problem with flashlights is that you have to make sure you always have fresh batteries. Durable flashlights tend to be heavy and bulky too. Using light sticks (a.k.a glow sticks) that you crack to activate, solves these problems. You no longer have to worry about batteries and the light sicks fit in your tool roll with ease. These Industrial Strength light sticks from Cyalume are durable and weigh close to nothing. You can get 8 hours of light from a single stick and the white sticks put off enough light to work by. You can light up the area around you while keeping your hands free, when you hang a light stick around your neck with a lanyard.
