Example Wiring to Eckon or Berko 4-aspect Signal
The positive connection from each of the leds in an Eckon or Berko signal match the
led colour (red wire for the red led positive connection, etc).
Depending on the age of the signal, there will be one or more white wires. These
are the negative connections to the leds.
The exception is the top yellow led of a 4-aspect signal. This has a blue positive
wire and may have a black negative wire (or it may share a white negative wire with
the rest of the leds).
The following wiring diagram shows the most common wiring arrangement.
