Anytime an emergency vehicle - ambulance, tow truck, police squad vehicle, or even a fire truck for example - comes screaming past you on the highway, the blaring siren and flashing light you see is very likely a emergency Whelen LED light. Contracted by various emergency, medical, as well as law enforcement agencies, and Whelen LED light can be seen on many modern emergency response vehicles. But in spite of their ubiquity, the Whelen LED light isn't just a time honored technology. LED lights themselves are actually a far more recent creation of the past ten years perhaps. LEDs, or Light Emitting Diodes, have been available since the 1960s, though their application has long been for a long time limited to low-energy indicator lights as part of larger bits of technology - for example the gas or break lights on the HUD of your car. At low amounts, the energy usage of LEDs is more efficient compared to incandescent bulbs - the other well-known means of projecting light in technological applications. That is why for the past several decades LEDs are actually restricted to use as small indicators for small appliances and the sort. Nevertheless, just one large LED projecting a substantial amount light would not be energy efficient, consequently their limited application for a time. Grouping a great many small LEDs together however allows a device to project a practical amount of bright light at a minimal cost of energy. This finding has proven extremely beneficial to the application of sirens and emergency vehicle lights, hence the development of the Whelen LED light. A popular application of LED lighting that a lot of people are familiar with usually are traffic signals or stop lights. Only very, rather rarely are you going to see a usual red, yellow, green traffic signal whose lights are each comprised of a single large bulb. The energy usage, heat generation, and brightness of such a bulb would not be effective - either the bulb eats excessive energy and becomes too hot, or is not bright enough. Most traffic signals are instead a densely compacted assortment of much smaller LEDs, that can project a very bright, visible spectrum of light at a cost of energy that isn't much dissimilar to just one bulb, but without producing excessive degrees of heat that might become a danger. LEDs are thence flawlessly designed for the Whelen LED light. They might come in a variety of sizes, several as obscenely small as the head of a wooden match, as well as in many different bright, vibrant colors (which usually depends on the semiconductor material used) which are perfectly suited to the color coded signals which are kept in mind while in the design of a siren. The end result is a system of emergency lighting that is bright, vibrant, easily visible, small on energy consumption, as well as minimal risk of overheating.
