The undertray comes with an OE style lens with a cutout to light up the plate. It doesn't come with blinkers, you'll have to decide what you want to do there. You could add the LED tail light, which has integrated LED blinkers - where one half of the tail light will change from red to yellow and blink. You'll have to ask them if there's any provision in that light to illuminate the plate, I don't know.
There's probably other EU outfits that offer up something similar, that was just something I found in ~ 1 minute of looking.
