I had a look at those yesterday, they look alright but it says that they're not road legal - not sure why, but worth watching out, especially as you're going to be using your headlights more over the next few months. I ended up getting these: https://www.amazon.co.uk/gp/product/B00MZQUGLK/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 They're not exactly a snug fit, which is weird, but so far so good.
Greg This need to be a careful choice. I purchased some for my sprint a few years ago from fleabay. Being a little ignorant to lighting but ran the bike all winter and spring was doing a job on the lights and to my horror the holders on the lens had gone all brittle broken. An expensive lesson learnt. Ride Safe. Joe.
