Another major defect of series lighting circuit is that as all lamps or bulbs are connected between line l and neutral n accordingly if one of the light bulb gets faulty the rest of the circuit will not work as the circuit will be open as shown in fig below. If you want the little led indicator light to light up you will wire the switch like this.

Wiring 12v lights in series. If you have 3 led lights 4v for each one. 12v light switch wiring on most 12v switches it seems like most of them come with a little led indicator light on the actual switch. In your case you should connect them in parallel to get the job done. Here you can see there is a cut in the line wire connected to lamp 3 so the bulb is switch off and the rest circuit is working properly ie. And from the parallel circuit rule number 3 we know that total current output gets divided by the number of parallel strings. Rule number 2 from the series circuit bullet points proves that 12v dc isnt enough voltage to run all 9 leds in series 9 x 298 2682v dc.
Christmas tree lights often use 12v lamps with 20 of them in series. Lights will have a pair of red and black wires coming from them. The supply voltage of 240v is divided equally between the lamps and as 24020 12v the lamps all work properly. Components required for leds in series 5mm white leds x 3 47ω resistor 14 watt 12v power supply connecting wires breadboard. As stated above with series wiring the voltage is shared between the lamps. Accordingly when you connect many led lights in series the 12v is going to be divided equally among the led lights.
Thus if you have 2 led lights 6v for each one. However 12v dc is enough to run three in series 3 x 298 894v dc. This means that all of the red wires will be connected together to run to the switch. A 40 lamp set would have 6v lamps. Start by wiring all strips or strings of lights together. Because everything is already 12v you want to wire them in parallel.
