LED flashing lights are popular around the world

Now, LEDs can be found in almost every emergency vehicle lighting product that is available. And because they generate less heat and require less space than strobe or halogen lights, they have greatly increased light output while consuming less energy. Because of this, there are several factors in which led emergency lights benefit our environment.

First, most led flashing lights bars generally have a very low profile. Compared to the roof mounted light bars from even five years ago, the aerodynamic efficiencies are exponential. No longer do police cars and other emergency vehicles have to drag around a "parachute" on the roof. The older style halogen and strobe light bars were very tall and therefore created a lot of wind resistance. Low profile led light bars are so thin, that their effect on the overall drag coefficient of a vehicle is next to nil. LED undercover light bars and LED dash lights which mount inside the vehicle, directly behind the windshield, now offer the ability to have full size warning without any increase in wind resistance outside of the vehicle. The reduction in drag, multiplied by the hundreds of thousands of police cars, ambulances, tow trucks, etc. on the road every day, translates into a huge reduction of carbon emissions. Less fuel is required to operate the vehicle and therefore, not only are emissions reduced but fuel consumption is reduced which reduces operating costs.

Secondly, the energy required to operate and led emergency vehicle warning light has been drastically reduced. Incandescent and/or halogen light bars would draw upwards of 30 amps or more for a fully loaded unit. Now a completely decked out low profile led strobe light bar draws less than ten or twelve amps on average. What this means is that the vehicle’s engine is no longer devoting substantial energy to generate the electricity through the alternator. Again, less power consumption translates into the use of less fuel and therefore less greenhouse gas emissions, not to mention less heat generated as well. It is a big win all the way around.
