Can 12 Volt Circuit on a 2012 GMC Yukon 7-Way be Used to Power Two 55-Watt Halogen Utility Lights

Question:

Is the wiring of the factory installed 7 pole system sufficient to handle the amperage draw of 2 of these lights?

The amperage draw of 2 of the 55-Watt Halogen Flood Beam Lights, # QH16CTS, is 9 amps. This should not be a problem for a 12 volt circuit on a 7-Pole. You can check the owners manual and/or the legend on the lid of the power distribution box for the fuse that powers the 12 volt circuit to see what it is rated for to be sure. The amperage rating for a factory 7-Way might also be listed in the vehicle owners manual.

If connected to the 12 volt circuit from a trailer connector, the lights will be on all the time unless they are put on a switch. A simple switch like # BL0108-00 could work as long as you are not pulling more than 10 amps or # D16740 for up to 20 amps.
