LED Lights with 3 wires will be a multi-function light. They can (most times) be used in whatever configuration is right for your application. For example, running and brake, running and blinker or brake and blinker. These LED’s will usually have a black, red and white wire.

How to Wire a Light Bar in 4 Easy Steps

1. Use a Relay Over a Simple Switch. Even with the lower power draw of an LED, it’s still a better idea to use a relay instead of running full current through a simple switch.
2. Choose a Fuse.
3. Make Sure Your Grounds Are Good.
4. Decide on an Auxiliary Switch or Factory.

If not, then you can always purchase it separately. Always consider the LED light bar type and your vehicle’s wiring system when buying a wiring harness. Wiring can sometimes be tricky, so to steer clear of possible short circuits, always refer to your light bar wiring diagram.

Figured it out, yellow wire is for amber. That is what i wanted it for and they are bright! I am not using the red wire but if you want to switch between white/amber it comes with a wiring harness that i did not use. There are no instructions for the harness and it is not using conventional red/black/white wiring.

Yes, you can. Different color light strips can be used together. As long as the voltage and current used by each lamp strip are the same, they can be used together.

Yes, One remote can control multiple receivers, you need to match code with each receiver firstly,following the steps: . Use remote controller, hold the “ON” button 5 seconds, then LED strips light would flash ,it means the remote has paired with the receiver success… see more.

Wiring LEDs in parallel allows many LEDs to share just one low voltage power supply. We could take those same four 3V LEDs and wire them in parallel to a smaller power supply, say two AA batteries putting out a total of 3V and each of the LEDs would get the 3V they need.

Series components have the same current through them but fluctuating voltages. Generally speaking, most LED lighting uses a series-parallel combination. Ideally, for reliability and lighting consistency, it would be best to have one strip of LEDs all wired in series to a constant current driver.

Parallel LEDs – usually a bad idea. Many beginners ask why LEDs can’t be wired in parallel to share a common current-limiting resistor as shown in Figure 1. Well they can – but it’s usually not a good idea to parallel LEDs directly.

They last for many hours, and a gently used light can last up to 25 years. Most LED lights are arranged so that they can run off of a 12v battery—in fact, 12v lights can cause a short when plugged directly into a socket, which usually have 110v current.

An LED (Light Emitting Diode) emits light when an electric current passes through it. The simplest circuit to power an LED is a voltage source with a resistor and an LED in series. Such a resistor is often called a ballast resistor. If the voltage source is equal to the voltage drop of the LED, no resistor is required.

If an l.e.d. is to be used with a 12V supply it has to have a current limiting resistor in series with it. No. LEDs sold as 12v, already have a resistor.
