Lexus style rear light clusters going reasonably cheaply at

Get the standard 206 ones and chop them down yourself - lights are only £129.99 delivered 'til the end of October only.
It costs an extra £20 for them to chop the plastic down for you (10 minute job, I am sure the instructions to do it are out there)
