headlight switch

[wrongway]

Anyone know what the letters on my military light switch refer to? The only positions that do anything are all the way to the left which turns the headlights on and the convoy position which turns the light under the rear bumper on.

hst is head lights, side lights and tail lights,
ST is side and tail lights,
T is tail lights,
Then the off position, to the right,
Convoy lights,
S. Convoy, is Secret convoy.

On the Military 2A Lightweight I once had , the S.Conv. position put the sidelights and convey on, no head or tail lamps. See attached extract from military Handbook for S2/2A , the S3 Lightweight Handbook shows the same . The Infrared switch should extinguish all lights other than headlights.
