There’s no mention of how the Star Wars Phone Flashers actually work, but pfff, who cares, it’s Star Wars gear. This little cell phone accessory attaches to any handset via a key chain like connection, and from what we can tell will begin to flash and spin when it detects an incoming call over a GSM network (doesn’t work with 3G, though). Bluetooth would have been my preference, but that would probably drain the battery life on both devices faster than you can shoot a Womp rat.
The Star Wars Phone Flashers are each available now for $12.95 and come in Darth Vader or Storm Trooper.
Update: Looks like ThinkGeek has them for $10 and they’ve got the Yoda version.
