The 3 wire light can best be installed as a blinker and brake. The connection is LED lights and black lights with vehicle positive brake lights. Then the red LED light is connected with the vehicle blinker (positive).
The ground connection is the third prong on some plugs, not the two flat pieces, but the little rod, that's the ground connection in AC power cables for LED strip light Power Supplies, Power Adapters, and LED Drivers.
A standard box will have three sets of electric wires connected. There may be the black or red current wires, the white neutral wires, and the silver or copper ground wires.
If you do have a fixture using international standards, the good news is that the matching is very easy. Brown is your hot wire so you want to connect that to your building's black wire. The blue is negative or return, so that will go to white. Green with yellow stripe is the ground and will go to the building green.
There are three different wires. Each colored line represents a different wire. The blue line connects all the lights together in series and supplies power to the light bulbs. The yellow and red wires are both connected to the blue line on either side of the light bulbs.
The positive pin is the ANODE (+) and the negative pin is the CATHODE (-). It is very important that LEDs are connected to a circuit in the right direction. The current flow can flow only from the ANODE (+) terminal to the CATHODE (-) terminal. If the LED is connected in the wrong direction it will not illuminate.
LEDs are wired in series-parallel just like the traditional bulbs we described above. Unlike incandescent lights, however, LEDs do not typically make use of shunts.

The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.
The positive side of the LED is called the "anode" and is marked by having a longer "lead," or leg. The other, negative side of the LED is called the "cathode." Current flows from the anode to the cathode and never the opposite direction.
The white will normally be the ground(-) and the black will be the positive(+). 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.
Hint:LED is provided with two terminals: cathode and anode. Cathode is connected to the negative terminals of the battery and anode is connected to the positive terminal of the battery. The LED is provided with longer and shorter leads for their identification.
One wire is the anode (positive) and another is the cathode (negative). The two wires have different names because LEDs only work in one direction and we need to keep track of which pin is which. One goes to the positive voltage and the other goes to the negative voltage.
The negative side is called the cathode.
The longer lead of the LED is called anode and is the positive terminal, so should be connected to the positive terminal of the battery. Similarly, the shorter lead of the LED is called cathode and is negative terminal, so it is connected to the negative terminal of the battery.
Incorrect polarity connection that has caused LED failure will typically result in no light emission and open-circuit LEDs. This could result in signatures ranging from no naked-eye/visible signs of damage to physical damage including signs of burn/overheat.
: a constant potential system of electric distribution in which lamps or other receiving devices are connected between either one of two main conductors and a third wire and motors and heavy duty appliances are usually connected across the main conductors.
Three-conductor wire has two hots — black and red — and a white neutral. Though normally used for three-way switching, three-conductor wire is commonly used for duplex receptacle wiring as well.
Here's a rundown of electrical wires: The black wire is the "hot" wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the "neutral" wire, it takes any unused electricity and current and sends it back to the breaker panel.
All the wiring that is commonly used in houses is perfectly fine for use with LEDs. Many LED fixtures have a transformer already built in and can be connected to a standard electrical outlet. Some LED products, i.e. LED strip lights, require an external power supply.
Gently push each section of the strip light into the connector piece. Use the small clamps on the connector to snap the strip lights in place. Be sure both sides of the strip light is facing the correct way. The polarity needs to be correct for voltage to run through.
Tip. The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.
