As technology evolves and improves so does the use of emergency lights not only for emergency vehicles but also on home alarm systems and industrial warning devices. Many have been using strobe lights as it is capable of flashing up to hundreds of times per second that is very significant for aircraft use as anti-collision lighting. And even how useful it may seems but because of high costs and maintenance it is now slowly being replaced by LED technology.
LED or Light Emitting Diode is now the preferred lighting device as it has many advantages to other type of light sources. It can reduce the overall power costs because it only consumes lower energy, longer lifetime and come in smaller sizes. Then you aren’t going to have big electrical wastes as you can replace only those busted light and not the entire lamp or lighting system thereby, minimizing the replacement cost. And in the long run, it will help minimize the global energy consumption and reduce greenhouse gas emission and a potential reduction in global warming effect.
