We recently saw the Turn Signal Jacket. Good stuff, but not great if you live in a hot climate. The alternative? The Bicycle Direction and Brake Lamp with 8-tune Horn. Looks like it attaches with ease and available here for a measly $15. Course, to use the turn signal you have to hit a ‘far from integrated button’ partially defeating the safety it hopefully achieves. The brake light can be hooked up to the brakes, though.
Grew up back East, got sick of the cold and headed West. Since I was small I have been pushing buttons - both electronic and human. With an insatiable need for tech I thought "why not start a blog focusing on technology, and use my dislikes and likes to post on gadgets."
