cheapest place to get rear lights.... for avant

[quattrodragon]

the soft plastic surrounds on my rear lights have gotten hard through time and snapped off so basically the water will just run inside the body.. which means I need new lights as it looks like the plastic trim is a part of the light housing and cannot be replaced..

does anyone know where this can be sourced cheaply? I’ve looked at a few online places and they are ~£150 per side + VAT
