It's easily done – cracking or breaking your rear light cluster. I'm sure the first thing that comes to mind is "How much is this going to cost?".
No need to worry, the costs are not too great. There are plenty of suppliers on the internet selling on eBay or their own websites – it's even possible to buy direct from Japan.
Genuine parts are available and expect to pay around the £100 mark.
Mazda Bongo and Ford Freda use the same rear light cluster.
