Hello, I'm C.Fred. I noticed that you made a change to an article, Traffic light, but you didn't provide a reliable source. It's been removed for now, but if you'd like to include a citation and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Blogs are not reliable sources; you may not use a blog as a source. Thank you. —C.Fred (talk) 03:07, 22 February 2013 (UTC)
