Okay a little help here guys, please! I need the wiring diagram on how to make the LED brake light into a running light and a brake. Some one else needs your help....I have the diagram at home but I have no way or know how on how to post it....thanks!

This is just a little more involved, requiring construction of a simple circuit and tapping into both the brake and running lights rather than one or the other (depending whether you installed the LED strip as an additional brake light or a running light)

The purpose of this circuit is to supply a lower voltage to the LED's (about 8) in "normal" running mode. A 330 ohm resistor is used to drop the voltage so the lights are a bit dimmer. When the brake is applied, the circuit allows a full 12 volts to reach the LED strip for full brightness.

As shown you will need a bit of wire about the size of the wire supplied with your LED strip (about 20 gauge.

2-4003 Diodes which provide a power gate so the 8 v doesn't make its way to the 12 volt brake light circuit and the 12 volt brake light power doesn't get into your running light circuit.

1-330 ohm resistor

Make sure the diode is downstream from the resistor on that "blue" leg.

All of this can take the space of a quarter. The parts and wiring needed is very small. Legs of the "Y" need only be long enough to reach the appropriate wires under your seat.

By popular request, below is a photo of the actual circuit. Note the whole thing is about an inch across (less if you want to tighten things up a little more than I did here).

This photo mimics the circuit drawing shown above. The top leg (left) contains both a resistor and diode (note orientation of diode with silver stripe to right). This is the 'running' light side. The lower leg is the 'brake' side and contains only a diode. Wire to the right connects to the hot wire of the LED strip

Same circuit with two legs individually shrink tubed and then a larger shrink tube over the entire circuit
