Didn't count the number of flashes per minute. There are two speeds. One is slow, the other is pretty **** fast.
Didn't measure the distance either.
The white bottom lights flash.
I've tried Firehouse. They are expensive and not nearly as good...
Do your lights Flash 40-100 times a min?
Are they visible from at least 3 miles?
Do they Flash and are not "solid" or non-flashing? Non Flashing is not legal (you can have them but they do not satisfy the requirements for night time lighting)...
