On a different car , the fog light glass broke on one side , on eBay I found some led lights they were less than 20£ and came with brackets job done , the original fog light was about 110 £, halfords do a range too , probably cheaper easier route to replace ?
I'm needing a couple for my RB5, struggling to find new ones, could be an idea to check with somebody breaking the same car, quite a few people doing that on Ebay. Failing that I think I'll have to use the one that hasn't rusted away as a template to make a new one myself :/
