1974 Ex-mil 109 rag top

I have a curious little button switch type thing that I don't even know where to begin to investigate:

It's the lower one - the round one that gets me (t'other is the brake test switch)

I can't even tell if its a micro-switch or a press/hold doodah.

Its not short of wires

Any pointers? hints? jokes?

Probably infra red lights?

Hazard warning switch. It's a push-on / push-off type switch. The silver box in your first pic is the military-type flasher unit. The military wiring loom uses this flasher unit for the normal indicators and the hazards, so if your indicators are working it's likely the hazards will work as well (but all the lighting on a military series goes through a complicated master switch and relay system that often gets bypassed or bodged).
Lots of good info about the military series wiring on the lightweight site:

You begin by pushing the red button!!
Then you find its only the hazard warning lights

I did. Nothing happened.

If it's like mine was then it's jammed in and full of Iraqi sand. I vaguely remember taking it apart and cleaning/vaselining it all. If you're feeling brave the rotary light switch will need stripping too because the gunge eventually causes them to arc and fail. After a clean they're perfect.
