LED turn signals are a popular modification for many car enthusiasts. Not only do they look cool, but they also provide better visibility on the road. In this article, we will discuss the 12V LED turn signal wiring diagram in detail.
What is a Turn Signal?
A turn signal is a device on a vehicle that indicates the driver’s intention to turn or change lanes. The turn signal is usually located on the left and right side of the front and rear of the vehicle.
There are two types of turn signals – traditional incandescent bulbs and LED bulbs. While both types of turn signals serve the same purpose, LED bulbs are becoming increasingly popular due to their longevity and energy efficiency.
Why Choose LED Turn Signals?
LED turn signals are an excellent choice for those looking to upgrade their car’s lighting. Here are the top reasons why:
- LEDs last longer than traditional incandescent bulbs
- LEDs use less energy than traditional bulbs, which can save you money on gas
- LEDs are brighter, making them easier to see in daylight and at night
- LEDs have a faster response time, allowing for quicker signaling
Wiring Diagram for 12V LED Turn Signals
Before we start wiring the LED turn signals, we need to make sure we have all the necessary components:
- 12V power source
- LED turn signal bulbs
- Wiring harness
- Relay
- Switch
Once we have all the necessary components, we can start wiring the turn signals. Here is a step-by-step guide:
Step 1: Connect the Power Source
The first step is to connect the power source to the relay. The 12V power source should be connected to the positive terminal on the relay. The negative terminal on the relay should be connected to the ground.
Step 2: Connect the Relay to the Turn Signal Bulbs
The next step is to connect the relay to the turn signal bulbs. The positive terminal on the relay should be connected to the positive wire on the turn signal bulb. The negative wire on the turn signal bulb should be connected to the ground.
Step 3: Connect the Switch to the Relay
The switch should be connected to the relay next. The positive wire on the switch should be connected to the positive terminal on the relay. The negative wire on the switch should be connected to the ground.
Step 4: Test the Turn Signals
Once all the components are connected, it’s time to test the turn signals. Turn on the power source and flip the switch to activate the turn signals. If the turn signals do not work, check all the connections to ensure they are secure.
FAQ
What is a relay?
A relay is an electrical switch that allows a low current circuit to control a high current circuit. In the case of LED turn signals, the low current circuit is the switch, and the high current circuit is the turn signal bulbs.
What if I don’t have a wiring harness?
If you don’t have a wiring harness, you will need to purchase one. A wiring harness is essential to ensure that all the electrical connections are secure and protected.
Can I use LED turn signals on any car?
LED turn signals can be used on any car, but it’s essential to check the local laws and regulations before installing them. Some states may have specific requirements for turn signals.
Do LED turn signals require a resistor?
Most LED turn signals do require a resistor to function correctly. The resistor is used to reduce the voltage and ensure that the turn signal bulbs do not malfunction or burn out due to the high voltage.
Conclusion
Upgrading your car’s turn signals to LED bulbs is an excellent way to improve visibility and safety on the road. By following the wiring diagram and using the proper components, you can easily install LED turn signals on your vehicle.
