    ^^A nice supply of tiny wire is a great place to start for parts.

    [​IMG]
    ^^A toggle switch is nice to have so you can activate the light and leave it on rather than a button that needs to be held.

    [​IMG]
    ^^These are a great source of parts. Fingerlights can be found at almost any dollarstore and comes with four different colours and all the batteries you could hope for.

    [​IMG]
    LEDs can only be powered one way. Only having the positive on positive and negative on negative will complete the circuit.

    [​IMG]
    ^^Step one, see how many batteries are requires to activate your light. In this instance, no less than three will bring the sunshine but it will also light multiple lights.

    [​IMG]
    ^^Seen here is the layout for the complete wiring.

    [​IMG]
    ^^Here we begin installing our lights. This model came with headlight pockets so I drilled them out and fit the LEDs in place.

    [​IMG]
    ^^The switch will be installed in the center console.

    [​IMG]
    ^^The taillights will be a single bulb which lights up all four pockets. A mounting shield will be put in place to both hold the LED and keep light from illuminating the trunk.

    ^^Now j00 need to begin soldering your wires to your LEDs. From here, you need to route the wires throughout the figure. Remember to leave slack in the wires for joints or areas that compress/extend.

    [​IMG]
    The wires all run up to a central point and connect to the switch.

    [​IMG]
    ^^A battery box is a must have but salvaging one from something else doesn't always work due to space. Here we scratchbuild a custom box out of styrene using several components from the fingerlight/

    [​IMG]
    ^^Begin by cutting out a slot for the metal band to fit through. Glue up your first wall.

    [​IMG]
    ^^Line up you batteries to determine how long the box needs to be. I've added an extra battery to this setup for good measure.

    [​IMG]
    ^^Set the other steel band in place.

    [​IMG]
    ^^Cut another slot into the other wall panel forcing a small amount of pressure on the batteries.

    [​IMG]
    Now we glue the end caps on and apply pressure to the walls until dry.

    [​IMG]
    ^^Test to make sure you have proper contact.

    [​IMG]
    ^^INstall battery box and fire up the lights. If everything works, it's time to begin soldering everything into place.

    Very nice.

    Just an observation to clear things up for novices.
    In post #1 pic 4 you have the polarities of the battery labeled in reverse. Generally the larger, flat side is the positive on button cells.:thumbs2: 

    Also a little tip again for novices. When you look at a brand new LED, one "leg" is longer than the other. The longer one is the positive.

    I'll probably end up using this sooner or later. One question, though.
    What is up with that thumbnail?!

    Hah, right when a customer asks me to wired LEDs into something. Nice timing. You rock.

    If I remember correct I've seen this model completed before...
    it was an all white race car from a cartoon (and later movie) but forgot the name :rolleyes: 
    but I could be terribly wrong hahah :D

    Very nice tutorial. Im new with LEDs and was wondering are resistors necessary to have when setting up 1 or multiple LEDs?

    I remember reading about it making the led last longer.

    If you want to use resistors to help control the needed batteries then you need to look up the color of the LED, tyically a 1Kohm resistor will do the job... just put it in series with each LED to get the correct current

    LEDs are current driven, so be careful using a lot of batteries. You might wind up with an over current issue that could cause a circuit-glitched diode-blowin' situation.

    While current draw isn't often a problem with simple circuits, resistor control is still a good idea to maximize battery and diode life. I like potentiometers for this, as they allow you to both control the mesh current and the brightness of the LED. You can find some that are pretty small, to boot.

    I just love how you make everything from scratch, with bits and pieces added in here and there.

    This tutorial was done over a year ago and one of the d00ds commenting on it noticed how bright the headlights were and commented, "Gah, my eyes, my eyes." I thought it seemed appropriate.
