The humble light-emitting diode comes in many forms but has a range of benefits over traditional incandescent bulbs or fluorescent lighting. For a start, they use significantly less current to produce the same level of illumination and have no warm-up period. For their size and current draw, LED lights produce a bright, intense light in a range of colour options, making them ideal for instrumentation in vehicles, warning lights and traffic signals.
