If you happen to own an old jalopy (or an entry level model that does just enough to transport you from point A to point B), then the TurnSmart Mirror System could be just the thing for you. This set of tiny stick-on wide angle mirrors come complete with solar-powered blinking LED lights that are able to operate just alongside regular turn signals, offering you greater visibility on the road whenever you want to make turns to the left or right. This is definitely useful if you don't happen to own a high end luxury set of wheels. This $149.95 purchase comes with a tiny transmitter that can be installed within minutes inside the trunk or under the rear bumper. Anything that helps reduce accidents on the road is always a huge plus point in my book.
