I'm currently planning on hooking up a 12v power supply to two different colors and have only one on at a time, the arduino will control them via a 12v relay. But I'm curious if these would need a resistor or would it have some onboard electronics/resistors.
Polarity doesn't seem to matter, terminals are labeled x1 and x2, here's the only spec.
Should I be worried about voltage drop/adding resistors or anything else you can think of?
Inside it's powering 6 tiny LEDs.
Number of Items 6
Part Number AD16.22D-2G2Y2R-12V
Style 12V AC/DC
