Nope. You are getting confused with LED turn signals they need a resistor or LED specific flasher relay to prevent hyper flashing.
i.e. flashing really fast. LED lights just need a 12v power source, nothing else.
Get some spare/scrap electrical cable and connect the Evotech plate lamp it directly to the battery to test it. If it doesn't light up swap the wires over. If it still doesn't light up its faulty.
