For the price and size of lights nowadays I'd personally just go with a couple either end. One flashing, one constant wins both ways. Fibre flares are good to attach to random bits of bike but I wouldn't rely on just one of those.
You do look a bit of a cock though and I do have a few twenty quid lights that I rarely take off my bike and hope they don't get nicked (haven't yet). Decent rear is attached to the saddlebag which I take the whole thing with me and decent front comes off in dubious places.
