I like the idea of wiring a low current draw LED strobe directly to the master circuit with no switch, just a fuse you can pull if you want to shut it off while working on the plane, pretty hard to miss, and you can lose the big strobe and the nav lights and the unused wires. These look good, much cheaper than the aircraft type, mounted through a hole with the rubber grommet or on the surface with the flange mount, draw 1.2 amps, about 4 cm diameter and 3 cm high: https://www.superbrightleds.com/more...g-lights/1905/
