Exterior battery voltage monitor

The Bay got me again
I get these e-mails from e-bay that says I 'might like these electronic items'
I'm kind of a geek when it comes to these kind of things... so... one of these cool gadgets was an LED panel voltage meter:

Blue LED 0 4" Waterproof Digital DC 12V 24V Voltmeter Car Motor Volt Panel Meter | eBay

Cool thing is that it's waterproof and draws near nothing to operate.
Plenty to choose from (just do a search). I chose blue.

VERY easy installation where I chose to put it because I simply tapped into the power behind for the light above.
This gives me a quick visual check of my battery charge.
It pleasantly surprised me that the parasitic 12V system current draw for my trailer are as low as they are. I can keep the 5er unplugged for over two weeks next to the house without any big discharge issues with a standard deep cycle battery.

It's bright out today, but I can still see it fine. Looks even nicer when it gets dark.





I hope I haven't 'infected' anyone else here
