After reading the Thread on Handheld VHF radios, it got me thinking emergency again. I came across these 2 years ago and got my company to buy a bunch. I use them on the Tarmac for directing visiting aircraft where to park. Saves a lot of chatter on the radio to common sense challanged pilots. We use them also on the Ice Roads in the winter time since we can't use real flares. These things are great. We use the lithium battery ones instead of the rechargables as they last several days even in the winter on a single battery and instead of waiting for a charge, you just change the battery. They are virtually indestructable, submersable, and you can put a magnet on them. I have some personall ones. You can slap one on the back of a trailer if you loose your lights. I plan on using one as an anchor light instead of leaving my power on. They are extremely bright and they have numerous light patterns to select from with the push of a button. They come in several light colors as well. They were so well liked at work, each employee where I work recieved one as a safety gift recently to bring home and put in their vehicle. Not sure if you guys have seen them before, but they are getting popular.
