LED Police Lights
LED police lights are compact and energy-efficient so that war zone equipment, police cars and emergency vehicles fitted with them can remain inconspicuous until the lights are switched on. Being inconspicuous is especially useful for police lying in wait at speed traps.
Implications - LED police lights are an energy-efficient alternative to the current lights. I think that this is a phenomenal concept that I would really to see implemented in cities across the globe. Just a great idea.
