We started using Birddog Distributing LED strip neon. There are two types...thick for large signs (LED neon rope), and thin (LED strip neon http://www.birddogdistributing.com/Brilliant-120-Volt-SMD-LED-Neon-Strip-Light-148-Feet.html ) for tight radii. Very reasonable pricing and our customers are happy. Customer service is great and they can answer all technical questions. Spent a lot of time on the phone with them first time around.
