I have a '53 3100. I installed my own back-up lights (I have a 120 foot long
driveway that is narrow, is curved and on a hill. I can't see squat without
backup lights). I went to my local truck (as in 18 wheeler truck) store and
purchased a brake light switch that is exactly like the original on my pick up.
I mounted it to the rear engine mount (I have a 327 with a Saginaw 4sp and a
Hurst rear engine mount...yes, Hurst). I bent the arm so it only contacts the
reverse linkage.
It is always in contact with the linkage to keep the electrical contacts open.
When I shift into reverse, the contacts close and turn on the lights. It is
strictly a series switch in the back-up light circuit...just like the brake
lights. Only I used the electrical circuit that is activated only when the
engine is in the "run" position.
It would have been better to use a normally open switch and mount it so it only
makes contact when shifted into reverse. This is probably the only way to do it
for a 3-speed because 1st and reverse are on the same linkage.

Subject: Re: [oletrucks] backup lamps
The Suburban I saw the original backup lights on was a 57, but they had
swapped in a late model automatic so the switch was not an issue.

Bob, my '58 Accessory Installation Manual shows the 4 speed backup light
switch mounted on a new gear shift lever cap with a trip lever mounted on
the shifter. The switch looks the same for all applications.

I stand corrected on this. It's in my 57 Accessories Installation Manual. I
have never seen this on a 4 speed in the field. Must be rare as hen's teeth.
do any list members have AD or TF back up lamps?
Checking 1954 and 55 first "Specifications", this is not on the Accessories
page, but is included in 1956. 55 second Specs has msissing pages. It
looks like truck back up lamps were introduced in late 55 or 56.
