Howdy, I need some help. I got my son a power wheels for wheeler for christmas and it needed some lights. I installed the lights and decided to use the battery that powers the car. I installed a SPST switch http://rsk.imageg.net/graphics/product_images/pRS1C-2266162w345.jpg and they work fine. The problem is when i use the switch to power them off the power wheels will not work. Is this due to and open connection? Im sure the power wheels has some saftey feature to kill the battery when this happens. Any help will be appreciated thanks.

You'll need to post detailed photos or an accurate wiring diagram in order for anyone to understand what the problem is. We need more information.

For a lighting circuit of this kind you would wire the lights to the wires that go to the two battery terminals.

For this project you should not have had to disconnect any of the existing wires. If you did then you probably created the problem that way.

What kind of lamp did you use? Traditional automotive turn signal lamps (let alone headlight lamps) draw a lot of power and the Power Wheels may have a circuit breaker that tripped on you. Or maybe the power draw was enough to melt the soldered connections of too thin wires they might have used and something has now fallen apart.

I am guessing that a Power Wheels would need at least 16 gauge wiring for the motor circuits, possibly 14 gauge. The same wire sizes (14 gauge for 15 amps) apply to 12 volts as apply to 120 or 240 volts. (For long runs, you actually have to upsize for low voltage applications; that's a ong story that is not on topic here.)
