This requires the most basic sewing skillz, so don't worry. I sewed the lights onto my Camelbak Blowfish. It has a small front pocket that is perfect for the battery pack and wires. The wires lead directly from the light blocks into this pocket.

1. Position the light blocks near the bottom of the bag. Since you are probably not sitting straight up on a bike, have someone help you figure out at what position the lights will have the best visibility. I found it was near the bottom of the bag, such that when I lean over into my normal riding position, the blocks are almost vertical, which means that the light is being projected out horizontally.

2. Punch a small hole through the bag. I heated piece of metal (like a not so hot soldering iron) will make a nice small hole that won't rip. Pass the wires through this hole.

3. Sew the light blocks on using the holes in the 4 corners. Thread the needle through the hole and into the bag a bunch of times until you have a secure wrap. Tie off the thread on the inside, and put a drop of superglue on the knot to keep it from coming undone.

4. Inside the bag, connect both positive wires together, both negatives, and connect to a 2 AA battery pack. Connect both of the switch wires together.

5. Push the switch, and if everything is wired up right they should both turn on. Keep pushing the switch to scroll through the different flashing modes.

Enjoy, and Ride.
