Just bought one of these yesterday ready for my holiday in France next month. It contains a hazard triangle, first aid kit, high visibility vest, beam convertors, GB sticker and a couple of books, all in a nice bag!
Just need to get myself a spare set of bulbs and I'll be ready to go!
Don't know if this is nationwide or not, but was definitely half price in my Tesco (Ruthin)
Remember - INSTORE ONLY! (Link is to Tesco Direct for information only - still £30 there)
