An extremely bright voltage monitor that weighs very little and is still very economical!  The MKD Onboard Monitor makes it very hard to accidentally leave your switch on, and it doesn't draw enough current to worry about.

This is almost a must for the new lithium ion battery installations, as you certainly don't want to accidentally leave your receiver on.  The unit comes with a JR plug that can be plugged into any spare channel, or a "Y" harness.
