A continuous horizontal road-marking tape is described. The road-marking tape includes Light Emitting Diodes (LEDs) or high intensity microlamps, solar cells and retroreflecting elements. The LEDs may be double and focused for better visibility, their light is pulsing at a regular speed or at an emergency fast speed. The road-marking tape balances the solar energy captured by its solar cells with the emitted light employed to signal or warn motorists. Also described is the use of an emergency fast pulsing for signalling an emergency or the presence of ice, and the use of the tape for controlling situations where a single lane of roadway must alternatively pass traffic from two different directions. Activation of the light emitting sources is by sensing light from headlights of oncoming cars or by traffic lights.

Continuous prefabricated road-marking tape, of the type which may be firmly secured to the road surface and which is resistant to the aggression of weather and vehicular traffic said tape including: (a) protective protrusions on the road-marking upper face; (b) reflective elements housed within said protrusions, so that a reflective surface is exposed to the headlights of an approaching vehicle; (c) light emitting diodes (LEDs) housed within said protrusions, and which emit light toward the approaching vehicle; (d) an electrical circuit extending within said tape and including solar cells; said light emitting, a photocell switch and storage batteries housed within and protected by said protrusions, said diodes being controlled by said photocell switch, such that said solar cells energize said storage batteries during the day and at night said batteries energize said diodes by an energy balance assured by a light detector which activates said circuit as signalled by an approaching vehicle headlight and wherein the light detector is provided with a light focusing unit oriented so as to selectively focus the light coming from the vehicles.
