To operate white LEDs in wire-guided vehicles with only two NiMH batteries, this small circuit is useful. It allows for the complete vehicle lighting to be realized using white and red LEDs. No additional resistors are required. The circuit can be powered by one (1.2 V) or two (2.4 V) NiMH batteries. The LEDs are connected in parallel to the corresponding outputs for red or white LEDs. Naturally, other colors can also be used here.
