Betelgeuse LED brake lamps.

Betelgeuse is a high intensity LED brake lamp with an integrated Flash Pattern Controller. It requires no modifications to your wiring harness and can be installed or removed as simply as replacing a standard bulb. Betelgeuse ships with 8 flash patterns that range from high frequency strobes to retro brightness ramps. In addition to the predefined flash patterns Betelgeuse is the first brake lamp controller on the market to offer recording and playback of your very own brake activation pattern. If you can tap it out on your brake lever, Betelgeuse can record and save your unique pattern for playback when you hit the brakes.
