    greetings earthlings,

    I am trying to build a gear indicator for my motorcycle. The shift lever moves up to choose a higher gear or down to select a lower gear. The motorcycle has a 12 volt dc battery. I thought about using six LEDs to show which gear I have selected, i.e. 4 LEDs lighted for fourth gear. No LEDs would light if I am in neutral. There is no speedometer in use.
    I would appreciate any design help with this project. I have wired control panels for stand-by generators in a previous life, so I have wiring, soldering and electrical schematic reading skills.
    Thanks for any help this list may provide me in this matter.

    Fred

    on my sport bike, i found that the neutral light worked off the end of shift cam
    with an electrical pickup. There is a spring loaded knob that makes connection to ground, when shaft is in N position. I made a new piece of plastic with more connection points.

    At first, i made it so it was 1 led lit at a time, then i thought id get fancy and buy a cheap $1 led digit common anode display.

    just take yours apart to see if its the same method of proving neutral.

    Edit: the display i purchased
