Classic/Antique Car Repair: old accesories, vintage models, united pacific

Question
Hello, I recently purchased a new car and I have trouble seeing the traffic lights when stopped at the stop line in the road. I enjoy cars and car shows of all types. I have noticed on some vintage models a crescent shaped prism/lens that reflects the traffic light color at the driver. Sir, what is the name of that item and is it available in either a vintage or modern model. I would appreciate any info you can share.   thank you, douglas

Check the following web site: http://www.amazon.com/United-Pacific-Traffic-Light-Viewer/dp/B002GQK72C The most common one used back in the day was the Guide, supplied by the Guide division of General Motors, but there were a dozen or so other makes.
