The bulbs on Kennywood's Bayern Kurve shine in a variety of hues, but they're all green to the operators of this historic amusement park on the outskirts of Pittsburgh. In a bid to see if anyone notices, the traditional incandescent lights on this ride and another at Kennywood have been replaced by LED ones, saving money on the park's hefty power bill and greatly reducing the frequency with which the bulbs burn out and need replacing.

The "itty-bitty" sign lights that look like CFL's are most likely cold cathode bulbs. They look very similar, but the tube inside is much skinnier. They're chaseable and instant-on. They also draw a lot less power than a standard CFL. (They're much more expensive, too.)
