Switch is on the side of the transmission at the operating lever.
Remove lever by taking out the pinch bolt and sliding it off after
unclipping the tranny shift rod to the shift lever. Get a new
bushing for the lever while you're at it, it's vastly easier to
replace with the lever off the car.
Unplug the switch (probably a round plug with a lock ring on yours,
might be a rectangular plug), then remove the three screws and take
the switch off the tranny.
Your's is dead, there is little point in trying to fix one where the
neutral safety switch AND the backup light switch is bad, it means it
has leaked and the contacts will be badly corroded.
Install new switch and bushing in the lever, put the link rod into
the lever and install the clip, then put the lever of the tranny.
Make sure the two "legs" of the switch actuator enter the slots on
the switch, don't bend them. Loosen the screw holding the actuator
to the shift lever, put the tranny lever in neutral, and use a small
drill to line the hole in the switch up with the hole in the
actuator, then tighten the screw. Usually quite close, they don't
vary much, so this step is easy,
Check for correct operation.
If you have slot head screws on the switch, consider getting three
hex head bolts to replace them, it's MUCH easier to get them back out.

Thanks Jim -
It's a Automatic Floor shift - I didn't mention it but the park/
neutral lockout is giving minor problems also (bumping the shift
lever makes it work) and since the BU lights and AntiStart switch
are inter-related/together, I am hoping the switch has loosened and
will only require tightening. (fingers crosses).
Hoping to work on it tomorrow. Sounds like the switch is on the
side of the AT rather than under the dash/etc.
Will try to report on progress Sunday - perhaps with some photos.
I was unable to find any info in the FActory WSM's (paper ones),
the CD or Haynes (I tend to try to find all info I can) ;-) so
perhaps others are in the dark like I was?
Later don't forget - the 12H of Sebring starts tomorrow at 10AM -

Subject: Re: [MBZ] Backup Light Sw Help Pls
Have a 78 240D W123 and the Backup lights stopped working
Automatic? Neutral safety switch, on the side of the
tranny. Not all that fun to get to, and usually quite
messy once you do. I repaired mine, but I was prepared
to replace it if necessary.

Stickshift? On the side of the shift mechanism up top,
probably. If it's anything like my 115.
