So here's basically the rundown between the two of them. Neons are more expensive and are in a glass sleeve which is find if your mounting them somewhere where it's gaurenteed nothing it going to hit them and crack the glass. The bad thing about neons are that they do fade and will eventually burn out. LED's on the other hand are made of a polymer (sp?) plastic so they're damn near indestructable and virtually never burn out. Neon tubes are larger and slightly akward to position. LED's can be bought as singles or in clusters. The singles are barely bigger then a 14 gauge wire and can be mounted virtually anywhere. The clusters vary in size depending on the amount of LED's in them. But usually you can pick up a cluster of 6 where the LED's are aimed in all seperate directions so you can get as much light coverage with one cluster al possible. Personally I'd pick LED's. I've used them extensively in cars I've worked on and I've used neon also, personally I like the LED's better, they're easier to work with because you can mount them anywhere. Either way you go, they're both 12v accessories which are easy to install but make sure you dont kill your battery running them. :thumb:
