IH 1066 Light Switch Terminal Markings

I am helping my neighbor put lights on a 1066 he just bought. I got a copy of the wiring diagram from the dealer. What are the terminal designations on the light switch mean.

Bat. = Battery
Instr. = Instrument Lights, I assume
T. L. = ???? Tail Light?
H. L. = ???? Wire goes to Front Lights; Head Lights?
R. L. = ???? Rear Light or Red Light?

The markings on the switch knob or decal are also tough to read. If you know those I would appreciate it. I assume something like High Beam, Low Beam, ????

Additionally, this tractor has a cab on it but the lights were all stripped off because they were Halogens and the dealer said don't run Halogens through the light switch. I assume because Low Beam simply runs a resistor in series with the light and too large a load will burn out the resistor.

I plan the wire the standard light switch to non-Halogens in the front grill of the tractor and the rear work light. Then I plan to put Halogens on the Cab front and back through a separate fuse and switch.
Comments.
Thanks, Paul
