Princeton Tec Pilot "Just in case"

The Pilot LED is a backup accessory light that is compatible with most headlamp straps. If you own a headlamp with wires connecting to rear or remote battery packs, you can replace the standard wire clip by using the Pilot system’s built-in wire holder. Weighing in at only 15 grams, the system will keep your load light. You can also opt to attach the Pilot to your backpack or hydration straps. Whichever attachment option you choose, you will have the security of always having a backup light nearby. The Pilot can be easily detached from its clip base for use as a handheld light or as a marking light set on the blinking/signaling mode.
