Socal is right, if they are too bright then you are following too far behind. It's actually probably a good thing all things considered. Brighter lights=greater following distance.
We have wig wags where I work on the ambulances, I don't use them at night.
Same here. Only use the wig wags during the day (if my unit has them). If the lights from the emergency vehicle in front of you are too bright then hang back because you are probably a little too close.
