Step 5: Power on the AC Adapter and You're Done!
If they don't light, no worries. These LEDs have polarity protection built-in. Switch the wires (you might have mis-wired group and negative) whilst the AC adapter is unhooked, and swap the wires, and you should be good to go!
These LEDs are pre-wired, so there's no resistor wiring, RGB controllers, or anything else to install, we've done it all for you !
