Just making sure! When I install my Led light into my frame, it picks up the grd from there. My two wires coming from the Led, are they both HOT, because either one that I touch 12v to it will light? Seems right but thats why I'm asking, thanks, Dana.

One lead is the (+) and the other is the (-). The LED will only light up with the HOT wire (source) hooked to the (+) terminal and the (-) terminal to ground.
Reversing the leads will result in the LED not lighting up.
One lead is usually a brass terminal (+) and the other is silver in color (-).
I was only thinking of a single LED that is used as an indicator light. What you have described is actually two (or more) LED's encased in a "bulb" and is pre-wired where the exposed terminals are connected to the source (+) and the main body is connected to the LED's (-) terminals and then the body becomes the ground.
After posting the above (which is based on my own experience) I did a search and found the link for LED's which has some good info. Scroll down to the bottom for info on available combo brake/taillight "bulbs" to replace conventional bulbs.
Some LED's have one terminal longer (+) than the other while the shorter terminal is the (-). Others are pre-wired and the RED wire is the (+) while the BLACK is the (-).
