Reflective stickers on helmets are a 'safe' bet and are mandatory in some countries. The exact legislation for France is that all helmets must have four reflective stickers: one on the front (although this sticker may have to split around the vents - in reality), one at the rear and one on each side; The surface of each sticker must be either 18cm2 (approx. 4.8cms diameter circles) and, within each sticker, you must be able to draw a 40 mm diameter circle, or it needs to be a 12.50 cm2 rectangle with a minimum of 20 mm length (that means a minimum of 6.25cms x 2cms).
