They're called sequenced flashing lights (SFL) and their in the AIM ch 2.


What is that thing that the beginning of the active runway that has
flashing
lights that flash sequentially toward the runway. I think it was about 4
or
5 lights. My instructor calls it a rabbit, but I can't find it anywhere in
the AIM. Whatever it is, is it listed in the AFD upon whether or not the
airport has it?
