DC 24V Three Layers Machine Light Led Indicator Signal Tower Industries Flashing Light

Product works great! I'm very pleased as it was a bit of a gamble given the lack of information. The connectivity is very straight forward - works on 24VDC not 12VDC as the title suggests. Each light is quite bright with 16 LEDs per light. Each LED pulls less than 40 mA.Connectivity diagram is a bit confusing - it's showing how you could connect to either a NPN or PNP transistor. A transistor is not required - it works on a simple DC circuit. Wire colors are as follows:Red - red LEDYellow - yellow LEDGreen - Green LEDOrange - buzzerBlack - DC COM
