I can't comment on Luftwaffe requirements, but most RAF runways were completely unmarked. Sometimes, rarely, there were locally applied runway numbers painted on the ends, but nothing more. They should - even through to the end of the war - have been camouflaged, but to be honest, once the Allies had air superiority, no-one bothered.
The edges of the runway would be marked with "gooseneck" flares that could only be viewed when on final, or by electric lighting that was hooded to prevent aircraft not on final from seeing them. What's more interesting is that US bomber fields, in particular, had so much lighting for approach and landing guidance, that you could quite happily use the FSX default lighting! (REIL, LIRL, taxiway lighting, approach guidance and funnel lighting...)
