  1. One great feature of having a super bright LED Flashing lights or torch is that it will give bright light using simple AA or AAA batteries . The LED Emergency light will also run longer on these batteries than the regular incandescent bulb strobe light. The brightness of an LED Warning light depends on the power output from its energy source. Super bright dash light used by policemen use about three watts. The lumens or bright light of Police light is at ninety lumens. The power input and output also determines the hours that you can use your batteries with the LED flash lights.
