For those that want something a little more descreet, I used one of those "Plug into your cig. lighter" type LED meters. Green is good, yello is caution, & red is, well, dying.
Gutted the unit and used the board & LED's in a smaller case, filled it with epoxy for waterproofing and then mounted the 3 LED's up top where the windscreen meets the dash cowling, Looks great, clutters nothing and is very functional! If anyone wants pic's I can post.
