I'm not so concerned about red vs. blue emergency lights, I'm more concerned about the trend of all warning lights on any type of emergency vehicle being LED's.
I do agree that they are much more visible in the daytime but I do believe they are a hazard at night. As an example the police department I dispatch for had an officer struck by a passing motorist one evening while he was on an ambulance call. He was seriously hurt but I'm happy to say that he's back to full duty. Anyway, the driver who struck him said that they were blinded by the warning lights on the police car and ambulance. At that time all our PD/FD/EMS vehicles were equipped with halogen-bulbed lightbars. We now have several PD vehicles with the LED bars and our new ambulance is fully LED'd out. We just ordered a new 100' mid-mount tower for the FD and as I understand things it will also be fully LED. I was driving to work for a midnight shift when I came upon a county deputy on a motor vehicle stop. His vehicle had an LED lightbar and, at night, it was so bright that I never saw the officer until I was almost past the vehicle he had stopped. It took several minutes for my night vision to return to normal, even with looking away from the lightbar.
Officers must wear reflective vests or jackets when on traffic details and road jobs, but the two departments I've dispatched for have no requirement for reflective vests or jackets to be worn when on regular patrol. Even if there was a requirement I'm not sure they'd been seen over the intensity of the LED's.
I know it would probably cost more but it would seem that a good compromise would be to have the forward facing lights be LED's but leave the rear facing lights halogens or some other type of lower-intensity light so that drivers coming up behind the incident aren't blinded, possibly causing more incidents.
Just my thoughts........:wink:
