I have a series of LEDs I would like to have display at 2 brightness levels and am confused how to properly wire this. This is for additional running lights/brake lights on my bike.
LEDs - Typical Voltage 2.2V, Max Voltage 2.6V, Forward Current 150ma
Source voltage 1 (running lights): 11.5V
Source voltage 2 (brake lights): 0.5V at all times, 11.7V when brake is engaged
When using the series LED calculator I believe for the Source voltage 1 I should set the forward voltage to 1.1V and 75ma (half of typical voltage and half of forward current) and then set the Source Voltage 2 to 1.1V and 75ma (the other half of voltage and forward current). That in my eyes would result 2.2V and 150ma. http://led.linear1.org/led.wiz
Is this right or should I be approaching this wiring different?
