I think I have seen the P11 headlamps refered to as quick release. What do you do with all the headlamp harness wires if you run without a headlamp. The ammeter wires need to be connected for it to spark. However it looks like the headlamp harness is still not disconnectable from the main harness, which leaves a few hot wires exposed to short out. I have broken a couple Lucas leadlamps and dented buckets and gauges. Not by me crashing, but by a improvised sidestand someone put on. After the 2nd time, I removed the crap sidestand but it also showed me the high vulnerability of the headlamp if the bike falls. Important for me as I ride it off road.
