you both are sorta right.
In Nicks defense, he is correct in that if the starter solenoid does not engage then the starter won't draw any significant juice and the lights will stay bright. Time to look in the Start/security Circuit. If the lights do DIM, this does not mean the starter is shot, probably is but you'd have to rule out other possibilities first such as hydrolock, defective battery, corroded cables/connector...
in 1993 SLE'* defense, this only works if the starter gets physically stuck and it only works sometimes in my experience.
