LED collar for finding your dog or rocket at night

Below is a link to a simple led circuit that allows you to find your dog or rocket at night.

It is in standby during the day, and activates a string of LEDs at night. Could also be used to activate a beeper. A rocket with flashing LEDs at after dark should be relatively easy to locate.

The LED would definitely be useful (and fun) for our upcoming fall night launches!

I was also thinking you could add it to the Garmin Astro GPS system for full fledged \"canine inspired\' rocket recovery.
