Update to the Gammatronix LED battery monitor.
I love this little LED! What I didn't love was my mounting location.
Usually I think these things through rather thoroughly before I drill a hole in the dash but, as they say, shit happens. The original location up near the vent caused a bad reflection from the LED into the windshield. While these LED's aren't terribly bright, it was an annoyance. Oh well, the fix (barring a new plastic panel) isn't too bad, right? I doubt most people would even notice...the pic shows a glare that isn't apparent in person.
So, to celebrate my errant hole drilling, I ordered another LED, and drilled
two new holes.

arty:
One keeps tabs on the main battery:left side, the other on my backup battery:right side.
Since the Gammatronix LED's are programmable I have the backup one set to ultra low power mode. It only draws 500 micro amps (nothing basically) in this mode.
Both LED's glow solid green while the battery is being charged, but display differently while being discharged. I can give more info on the "modes" if you guys want it! Pics:
Happy Modding!
