looks good..how are those plates legal ? a quick check on citizens info gave this result, calls out white background?:
The main requirements of the rules about the format of vehicle registration plates are:
The registration number consisting of numbers and letters must be in black on a white reflective background
The name of the county of registration must be in Irish, (examples are Baile Átha Cliath, Corcaigh, etc.)
The flag of the EU and the letters "IRL" must be placed on the left-hand side of the plate, the flag comprising 12 gold stars in a circle, the letters in white beneath it, all on a blue reflective background. No other numbers, letters, marks, etc., should appear on your registration plate.
