headlight control pod wiring question

[93Z]

in the headlight pod ( the one on the left for LHD). does anybody know what the bottom harness wires mean. Like the color with what its for? I know the black is ground and the red is your hot wire but theres two different reds so i was wondering if one is a constant and one switched? or is there no switch. Thanks in advance, sorry if this is confusing
