What are Dual-Color and 3-Color illumination types?
The Dual-Color type has two different colored LEDs on one board and the display surface is alternatively illuminated.
When lit simultaneously, a mixture of the two colors (e.g. red + green = amber) is illuminated.
However, please note that some models require an external resistor for simultaneous lighting due to heat.
The principle of 3-Color type is the same as Dual-Color type, but due to heat, the circuit of simultaneous lighting is independent from other circuits.
3-Color type is available for BL, CL, HL, TL and 3L indicators.
