LH light is when the hand pto clutch is lifted or when the clutch pedal is completley depressed.
This light is in the circuit for the air solenoid for the pto and is not, as standard, wired through the key. It is a good idea to re- wire this through the key because the battery will be flat if the hand lever is up as little as 10 mm overnight .
The other one is for low air pressure, not needed because you have an air gauge.
To turn the lights on turn the key 2 clicks for headlights. Put the dip lever in "dipped" position and turn the knob that is on the left of the dash panel clockwise. the cab roof lights should then come on and the headlights (probably) will go out. this prevents the total load on the alternator exceeding its capacity when the fans and wipers are on....
