The Smart KRONOS Duo model is similar to the KRONOS Duo model, in the sense that it integrates within the same LED optic the pedestrian figure (red or green) with a backlight.

The KRONOS model is a LED optic with a countdown timer function. This option is independent of the pedestrian module, and can be installed on a third extra traffic light module, or independently if used for other applications.

The KRONOS GR model is a bi-decelerating LED optic in a single bulb. This option is independent of the pedestrian module, and can be installed on a third extra traffic light module, or independently if used for other applications.

The KRONOS Duo model integrates within the same LED optic the figure of the pedestrian (red or green) with a counter which ideally should be of the complementary color (green or red), so that it is not necessary to use a third extra module to display the remaining waiting or passing time.
