The Versatile LED Strobe
One of the most versatile and effective methods of calling attention to your emergency vehicle is through the use of LED strobe lights. Police cars, ambulances, and fire trucks all use some form of LED strobe to provide visual warning of their presence; in many cases, police cruisers use only their lights to execute a traffic stop rather than turning on their sirens to alert the driver. This demonstrates the effectiveness of LED strobe lights in attracting the attention of motorists and ensuring that they are aware of emergency vehicles on the road, and explains the continued popularity of these emergency lighting solutions. Few sights can convey the same impact as the familiar flashing blue and red LED strobe bar atop a typical police cruiser.
Although they are a relatively new technology, LED strobe bars are quickly becoming the standard for newer police cruisers. LED lights are more environmentally responsible choices, since they produce less heat and use less energy for the same amount of light, making them a preferred choice in many progressive communities. Mini LED strobe bars may only contain two to four bulbs, while full-sized models may contain 150 or more bulbs in total. Because LEDs are semiconductors, the color produced is dependent upon the materials used in their construction; for instance, LEDs manufactured with aluminum gallium arsenide glow with a bright red hue. Indium gallium nitride LED strobes flash green, and zinc selenide creates a blue color in the LEDs produced. Certain colors are produced by combining two LEDs; for instance, purple LED strobe lights are usually created by combining red and blue LED bulbs in one strobe element.
Because LED strobe lights and bars can be exceptionally bright, it’s advisable not to look directly at the LED device when it is in use. Other than the risk of temporary flash-blindness or blind spots due to direct visual exposure, LED strobe lights are exceptionally safe; in fact, most LEDs are rated as extremely safe under nearly all conditions due to their solid-state construction, low heating potential and high level of shock resistance. LED strobe lights last longer and are more reliable under heavy use than other types of emergency lighting bulbs. Additionally, LED strobe lights can be programmed to switch on and off far more quickly than other types of bulbs with less after burn than traditional incandescent or fluorescent lights. Extreme Tactical Dynamics offers a wide range of LED strobe lights, including mini LED strobes and other emergency vehicle lights.
