I have something similar to this, but it looks different. It's all red-reflective plastic, however it's not flat, the bit where the keyhole is for the boot is flush with the lights, and only indents back for the number plate area.
Have a look here:

I like how it looks on my car, but I guess it only looks good with dark coloured cars, and definitely with euroclears -- with the OEM ambers it looks crap IMO. But to each their own.
The part number of mine was: 82129401095 (I think, I'm putting trust into realoem.com)
