If you are using HIGH-bright 5mm white LEDs, these LEDs drop 3.2v to 3.6v and require 20mA current.
This means you can put 3 in series with an 82R 0.25watt resistor.
You can now put as many LEDs around the number plate as you like by making strings of 3-LEDs.
To make the whole assembly "water-tight" you can cover the wiring with clear silicon sealant, but since the voltage is very low, dirt and water will not cause any problems.
