I thought the REIL was the 2 white blinking lights on each side of the
runway threshold.
The "rabbit" is the RAIL or strobe-like lights leading into MALSR and SSALR
type approach lights (according to the legend on page 4 of the AF/D). To be
honest I've always had trouble remembering the subtle differences of the
different approach lights (ALSF, SALSF, MALSR, etc).
Page 9 does say ALSF1 and 2 have "Sequenced Flashing Lights". Are these the
same thing as the RAIL/rabbit? My AIM is in the bedroom, and if I wake up
the wife I'm toast... :-)

Well then, what *is* the correct answer?


The "rabbit" is an ALSF - Approach Light System Flashing (or Approach
Light Sequenced Flashing, depending upon who you're asking) "which
appear to the pilot as a ball of light traveling towards the runway at
high speed (twice a second)".

The "RAIL" to which you referred is actually a "REIL"; Runway End
Identifier Lights which is a system that "consists of a pair of
synchronized flashing lights located laterally on each side of the
runway threshold".
