VLANDD2S LED Headlight Bulbs All-in-One Bulb Conversion Kit Super Bright Xenon White for High/Low Beam, 8000 Lumens, 6000K, 80W, YLB-LED-D2S

If i purchase this for the vland headlights that i just got for my 2015 frs will they work with just this kit? the headlights don't come with bulbs

What part you connect the two Sliver prongs to?

Why do the lights flash and click when not on?

Will it work for 2015 Jetta with Demon eye headlight? Can’t find bulbs yo fit ballast
