REFLECTOR: tach

[Brian Michalk]

Three pulses per revolution.
I don't know anything about the lightspeed, other than it looks like 
capacitive discharge rather than inductive.  In that case I would 
suspect three pulses per revolution as well.

If inductive it's possible to use a wasted spark configuration.  You 
would still have three triggers per rev, but six sparks per rev.
