Zeroflat24: This is Robert with XB Lights.
I was going to email you this, but its probably good for anyone else who might run into the same issue on the boards here.
There are a few options for license plate illumination.
In your case, you've already chopped the tail and painted it. Going back and re-cutting the small section for the light to shine down through would be a pain due to having to re-paint it.
One option would be the small LED license plate bolts. They arent very bright, but they light up the plate good enough to be legal to most officers.

(If you have a cycle gear close by, they had them on sale for $15)
Or you can go with a plate trim that has the LEDs built in...

Or a simple LED strip such as this..

Or I can put in the 10 LEDs into the tail light housing you've ordered.

(Please note, the LEDs I currently use for the license plate LEDs have a blue "tint" to them. The ones pictured are an old stock that has been discontinued)
Good luck! and if you'd like to change your order up, just let me know.
Thanks
