My back light's had a couple of funny turns recently - switched itself off mid-ride. Thought I'd fixed it, but just to be on the safe side I mounted another directly above and used both. Only when switching off did I notice that the two were running on slightly different blinking cycles - one would do 10 blinks in the time the other did 9. Which meant that they went in and out of sync on a cycle (as it were), between simultaneous and one-blink gap. The combo was curiously compelling ('are they in sync...yes they are....ah, no they're not....they're coming back together now etc etc') Impossible to ignore, I thought. Positively mesmeric. The only danger, I guess, being a driver getting so fixated they lose concentration and steamroller both at once...
