wiring help, number plate light not working

[formula400]

Right got an issue I am not sure how to solve.

I fitted a tail tidy to my MSX 125 and it come with a number plate light, also fitted new mini indicators (I know they are good and work as I have them on my triple)

I've fitted a flash relay unit as the indicators are LED, ive wired it all up and the indicators flash and work normally, but the number plate light will not work. At first I though the light was broken so I removed it and hooked it up directly to the battery and it lights up with out issue.

so the long green and yellow wires are the number wires coming from the original harness. (the picture below is the original harness)
I striped back all the white tape to see if they was a loose connection or anything and I can't seem to see an issue, now the 2 green wires join at the bottom (in picture looks ok and does not seem loose.)

not sure what to try next.

used the multi meter, reading off the battery is about 14v
then the green and yellow wires them selfs are 7.5v

Was the original an LED? Looks like resistive wire. Why not job in a feed from the tail light supply or fit an led no. plate light?

right, complete bulls up on my part, I wired it wrong, sorted now.

cheers though Dave, that was going to be my next port of call
