When the left indicator is on, the dashboard warning light is powered by the left indicator circuit as you’d expect, but it uses the right indicator circuit as its ground path. The same happens in reverse when the right indicators are turned on this means is that a small amount of current will flow through the dashboard tell-tale ligSee more on matchlessclueless Wiring LEDs Correctly: Series & Parallel Circuits Explained Hopefully those looking for practical information on electrical circuits and wiring LED components found this guide first. It’s likely though, you’ve already read the Wikipedia page about Series and parallel circuits here, maybe a few other Google search results on the subject and are still unclear or wanting more specific information as it pertains to LEDs. Wiring a switch with an indicator • Infinitybox Also note that the polarity of the wiring to the switch is important. Make sure that you are looking at the wiring diagram that came with your switch and referencing our wiring diagram. If you follow these simple instructions, your switch indicators will light up when you turn on the switch.
