Strobe Lights One Of The Most Effective Hazard Warnings A Vehicle Can Have

Why are strobe lights used in emergency situations

? The main reason is they are highly visible. Any emergency vehicle needs to be seen and the strobe lights are very easily seen from some distance. With a 360-degree visibility, the strobe lights can be seen whatever way you approach, whether it is from the side, rear or straight-ahead. There are light bar units that offer this same visibility but the strobe is a popular choice, as they tend to be very cost effective.

The stroboscopic light to give it its full name had been round for many years. Although there is some controversy and debate as to when it was actually invented. The first written record of the use of strobe lights is in a seaman's manual for the Royal Navy in 1911. Some say that strobe lights were invented by Dr Harold Edgerton of Massachusetts Institute of Technology in 1926. It is said that he studied the effects of high-speed flashes in photography, which eventually led to his invention of ultra-high-speed stop-action photography in 1931.

Whoever and whenever the strobe lights were invented they have been invaluable to emergency services personnel over the years. Light bars and LED lighting units have in the main replaced the single beacon strobe that used to be seen on police and indeed other emergency vehicles. However, there is still a place for the beacon strobe lights and they are still on sale from many different suppliers. Whilst the strobe lights in use today are more likely to be halogen and LED, their effect is the same.

A slowly rotating strobe is a highly visible hazard warning and as such is still very popular with the police, fire departments and medical teams. There is a saying 'If it isn't broke don't fix it' and that is so true of the strobe. With the advances in technology, the strobe lights are even more effective as they are brighter and cheaper to use. Any LED strobe light is a good investment as it will be reliable, easily maintained and cause less drain on a vehicles battery than any other light type. strobe lights are often used in other areas as well, but in a more fun or decorative way.

Strobe lights are a common sight in nightclubs and some bars, as they can be set to flash in time with the music. Of course, strobe lights can still be used in photography and to highlight show vehicles and draw our attention to something. The fact that strobe lights are still in use shows that they are highly effective at what they do. Whilst we may not have the single rotating strobe on the police vehicles now, there is still a place for strobe lights as additional hazard warning on vehicles.
