Electronic Destination Signages (EDS) is a major feature of bus spotting in Singapore. It displays the operating service number and detail on the front, side and rear of the bus.


Currently, buses operated by Public Transport Operators in Singapore currently utilize either one of these three technologies :


The oldest form of EDS. Individual flip dots are turned using magnetic pulses to form the message. Illumination is done using florescent lighting.

Dot-matrix LEDEdit

Similar to the above, but the individual flip dots are illuminated by LED. This provides clearer visibility at night.

Full LEDEdit

Individual LEDs form the display panel, which is then lit to form the message. It requires the use of constant power; the refresh rate of the LED units vary between manufacturers.
