Our friends at Digital Artist Toolbox have been kind enough to provide this great Free download. The quality is terrific and I think that you should have no trouble finding some use for these.
“Ive made a few vector road signs and a traffic light for you to add to your toolbox. I had a lot of fun making them, especialy the traffic light. I hope you enjoy and find good use of them. The zip file contains Illustrator 10 format and a EPS format.”
