Really like the size and steps of sidekick - SureFire Sidekick Ultra-Compact Variable Output LED Flashlight, 300 Lumens

This Sidekick goes everywhere I go. The contour rests perfectly in the pocket without being too noticeable. Due to light weight of the light it to the same netting as my car keys without worry of damage to my vehicle. The steps and/or levels of light output work great for every application.
