A dim or lightly glowing light isn't (necessarily) a problem. My 72 exhibits the same behavior. If it glows as brightly as the handbrake/oil light, then maybe you've got a problem.
If it does bother you, you might try cleaning all of the spade connectors and contacts involved with the Alt, Reg, and the light, and the 14-pin connector in the engine bay, and it may get better.
However, your voltage is a bit high. If you like, you CAN open up the cover of your SEV regulator and bend the tab ever so slightly to adjust the voltage. Check out this thread from when I had voltage issues. Different regulator, but mechanically identical to your SEV.
