What color is illumination wire?

What color is the illumination wire? The wire that shows less than 12V at that point is the dimmer/illumination wire. Most aftermarket head units usually use an orange wire or an orange wire with a white stripe for this.

What does the orange wire connect to on a car stereo?

The normal use of orange and orange/white wires is orange is for variable voltage to control display illumination dimming (i.e. the head unit display dims along with the other dash lights) while orange/white is a simple on/off signal of whether the dash lights are on (the head unit has only bright and dim display …

What is the yellow wire for on LED lights?

The green/yellow wire is the earth wire. It is for safety in case of in internal connection to the body of the lamp, for example, due to abrasion of the insulation on a wire that is carrying mains voltage.

Why does my light bar have 3 wires?

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.

Can you wire LED light bar without Relay?

Although relay is a vital part to wire LED, it is possible to wire one without it. In this case, a switch can be used by determining the type of LED, power supply and resistor and wiring it.

Do I need a relay for LED lights?

A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.

When would you use a 12v relay?

12V DC relay switches are the best solution for full voltage applications, as they allow a low current flow circuit to control a high current flow circuit, like a vehicle’s horn, headlights, auxiliary lamps, fan motors, blower motors and countless pieces of equipment existing on vehicles today.
