thegermangemini May 24, 2004	Okay, for a flashlight, I could possibly see spending $40 for a good one, but a light bulb??? Someone shut those convicts down!!!

od-1 Jul 05, 2004	I have bought custom light bulbs for more than $60, and unless you have an L.E.D flashlight, all flashings have bulbs in them. Though I agree a flashlight would work fine as an answer.

bookworm91 Nov 10, 2005	i got that one cuz i watch star trek sometimes. im not a geek but hey as this teaser shows, you can learn from it!
