That reminds me...I saw a stop sign the other night. As I was approaching it it looked like the letters were black vinyl on red reflective. As it turns out, I realized as I stopped at this stupid sign, the fabricator of said sign, used red reflective and regular white vinyl lettering. From a distance, all you could see was your lights hitting the reflective and not see the letters at all...Just their outline.....REALLY BAD JOB!!! Be SURE to use both reflectives! Good luck!
