Low-cost, low energy, programmable and remotely activatable traffic signs, particularly suitable for roadside, waterside or comparable use, which signs can display a variety of messages or images, for example warnings and directions, employ electropolymeric shutter arrays in front of retroreflective materials ( 32 ). The signs employ daylight or other passive illumination external to the sign, such as vehicle headlights, to yield high contrast images with good visibility. Optional features include attention-getting effects such as flashing, economical solar power means and means to detect vehicle approach to initiate the attention-getting display, e.g. flashing.
