Trust me, I have used those crappy neons, and these LEDs. The LEDs by FAR are better.
Here is an image of them in action.
The neons are the only ones that look ghetto. Plus, neons do not handle contrasting weather very well. You will end up replacing them around every 3 months..doubly so if anyone kicks them.
The LEDs are very very tiny, and are made for automotive use.
They come in strips you can cut to any length..plus they are cheaper, and use less energy.
But, I guess some people will continue to use neons regardless of good advice.
