There are certain features that make emergency lighting far more effective and efficient with the optimal usage of energy. Emergency lights should be highly reliable, but should also provide a wide variety of features that could help rescue or search operations in one way or the other. One of the most important assets of LED emergency lights for example, is their energy efficiency which allows you to operate them on a simple 12V DC power supply. In fact, the peak current in LED lighting circuits rarely exceeds 2 to 3 Amperes. Their energy efficiency stems from the fact that LEDs are known to provide greater luminosity for lower wattage, compared to incandescent lights or halogen lights. Moreover, less energy is wasted in the form of heat when LEDs are used.

emergency lighting needs to be flashy enough to grab eyeballs especially when you are trying to send across a warning message. For example, patrol cars would need lights that can be seen from as far as 500 meters so that information about a wreckage or oil spillage can be passed allowing drivers speeding towards the spot to slow down. In some cases, arrow markers on traffic advisor lights will help in diverting the traffic to clear out a jam or an alley to let rescue workers a freeway. One should be able to select the flashing patterns depending on the requirement. This is why some emergency light bars have pre-programmable flash patterns operating at slow and fast rates for different scenarios. Some light bars make use of colored filters and multiple segments of LEDs for more permutations and combinations.

emergency lighting equipment should be easily serviceable and upgradable. A modular construction helps in achieving this motive as each of the components in such a design are separately replaceable and accessible. Moreover, LED segments configured together allow you to replace or repair them when required instead of facing a situation where the entire equipment is down. Interconnect wires are used to sync the flash patterns on different LED segments. The phase control is a feature that allows you to operate random, sequential, continuous and alternating flash patterns on different segments. Light bars come with front and rear facing lights along with side LED modules as well, for 360-degree visibility.

emergency lighting equipment not only use advanced technology for easy operation but also boast of a rugged construction that makes them reliable even through heavy duty usage and harsh weather conditions. Extruded aluminum chassis for shock and vibration resistance and polycarbonate domes and bases for moisture resistance make the lighting equipment highly reliable and resilient. Due to the choice of materials, the lighting equipment is lightweight too, making it very portable. Sometimes, light heads can be replaced by removing just 4 screws. Mounting brackets and stainless steel straps can let you mount the lights anywhere. Staggered light arrangement of modules ensures excellent visibility in all directions. All these features make light bars extremely useful when it comes to providing lighting in emergency situations.
