Britax 4 ft, 4 module Zenon Beacon bar

Hi lads, I've a Brand new Britax4 ft, 4 module Xenon Lighbar with illuminated centre. I bought this for the truck but decided to keep the nameboard instead. It's still in the box with the fitting kit and instructions
I'm looking €400 for it, It was a lot dearer new
Cheers
John
