I'm not so sure I entirely agree with the sentiment that more lights can't really hurt anything. Perhaps it is because I work exclusively at night time or perhaps simply because I have had this happen to me several times over the past month or so, but I find that excessive lighting (emergency lighting, that is) can make it very difficult to see. Especially in the instance of some of the very fast LED flash patterns that seem to have become very popular, going from using relative night vision while driving to a scene to, all of a sudden, having to cope with extremely bright flashing lights can be very difficult--so much as to potentially make initially assessing a scene nearly impossible. I actually had an experience recently where, upon arriving at a call, was literally blinded by several flashing LED lightbars to the extent that my partner and I actually entered the driveway next to the one of our patient's (they were directly next to each other) because we simply could not see. While I feel LED's are fantastic for the daytime where traditional warning lights are very easy for people to not notice, I'm still not convinced that they are the best option outright. Perhaps more old-fashioned options or a combination of them with some LED's is worth considering?
