Girling brakes had the quirk of using natural rubber (later nitrile) seals, which caused difficulties for some American owners of British cars because of incompatibility with US brake fluids.

One-color light is well suited for traffic lights and signals, exit signs, emergency vehicle lighting, ships' navigation lights, and LED-based Christmas lights. Because of their long life, fast switching times, and visibility in broad daylight due to their high output and focus, LEDs have been used in automotive brake lights and turn signals.
