    Overview   Process   Hi Res  

    Task: To design new traffic lights for Istanbul.

    For the ISBAK company and the Istanbul city municipality our studio has designed a new traffic light from scratch.

    ISBAK services the Istanbul transport system since 1986.


    The traffic light is shaped as an exclamation mark—an established sign calling for attention and stressing important points. Yet the object remains instantly recognizable as a traffic signal.

    Istanbul has tens of thousands of traffic lights today.


    Svetoforus-2 is the world’s first traffic light to use signal panels based on the PHOLED (phosphorescent organic light-emitting diode) technology.


    The mount has a pivot and adjustable arm’s length, which allows you to rotate or tilt the body.


    Svetoforus-2 is equipped with a system developed in our studio that detects visually impaired and handicapped pedestrians. It uses special icons on the signal panel to warn drivers when such persons approach the crossing.

    There is a sound signal for visually impaired that also alerts other pedestrians and drivers.

    The back panel is black with a light-reflecting outline

    This modular traffic light is easy to assemble in any combination—just use inverted lower sections for any extras you need

    The first traffic light installed in London

    G. Morgan designed a cross-shaped traffic signal

    William Potts created the first three-section traffic light

    Traffic light towers appeared on Fifth avenue. They were twenty-five feet high and policemen operated them manually

    The Marshalite traffic signal used a dial and was created by Charles Marshall

    Three-section traffic lights became dominant in traffic control

    Traffic signals acquire super-bright LEDs, which consume less power

    Art. Lebedev Studio designed a traffic light with square sections

    Structure elements

    This traffic light is engineered to work with a base of any profile or diameter. Brackets are put in place with off-the-shelf tools and do not require particular precision.

    The Isiklarius is engineered down to four main elements


    The body and the visor are designed as one piece, allowing for easier installation, maintenance, stocking, and transportation as well as reducing the number of parts.

    With love for architecture

    For the Istanbul historical peninsula the traffic light is produced using natural materials.

    For the surface we used wood veneer with a varnish or special wood-imitating film applied.

    The body walls are tilted at a particular angle, improving the visibility and preventing water, snow, or dust from collecting on it

    Modular structure

    The upper portion with two sections is build as a mono-unit. It doubles as a pedestrian light, which further improves maintenance cost.
