Rear number plate light

[RyanWXM]

Just wondering what bulbs have people got in there rear number plate light??? LED/non-LED???? i have head LED bulbs are not allowed as they do conforms to EU standards but i would like a white light. Is there such a thing as like some headlights have the blue tint to the glass that cancels out the yellow light but for the rear number plate light??

Just after some info don't want no bother from the rozzers

Cheers
