Can an LED light bar to replace the police flashes of light passing in the night?
In particular, LEDs do not have the same effect strobe on cars, windows, traffic signs, such as strobe lights do? At night, strobe lights are very effective for early warning corners, and since I've never seen a police car, fire with LED lights, strobes and rotators only, I'm anxious to see if the effect is still there with LEDs.
Our department just recently switched to LED strobe lights to replace all of our patrol cars.I would say that they are much better strobes.The and efficient than LED's are also much brighter, so you can see the lights of a greater distance.
