The Ultimate Guide To Turn Signal & Dimmer

Turn signal lights the roadway for the driver and increases the visibility of the vehicle, allowing other drivers and pedestrians to see a vehicle's presence, position, size, direction of travel, and the driver's intentions regarding direction and speed of travel. 

A car dimmer switch is a switch inside the car that controls the brightness of the lighting. There are car dimmer switches inside the interior, overhead lights, and dashboard gauges. The speedometer, temperature, battery, and oil gauges are often lit by lights controlled by the dimmer switch. Most cars have two dimmer switches that work in different ways. One switch inside the car controls the dashboard lights and instrument patterns, adjusting them from a bright glow to dim light. Another dimmer switch controls the headlights, switching them between extremely bright high beams, bright low beams, and dimmer parking lights.

Have a look at the location of the car turn signal & dimmer:

Turn signals lamps are mounted near the left and right front and rear corners of a vehicle, on both fenders, and sometimes on the sides or the side mirrors of a vehicle. They come in different sizes and shapes. 

Some cars also have a third dimmer switch which controls the brightness of in-cabin lights, allowing passengers to turn on low lights when the car is driving so as not to disturb the driver.

Here are the important features of car turn signal & dimmer:

• Auto turn signal lights are mounted at the corners of a vehicle. It shows the direction of travel. 
• One or two green indicator lights are on the vehicle's instrument cluster, and a Tick-Tock noise is generated electro mechanically or electronically. 
• The headlight dimmer switch is the electrical switch that is used to control the vehicle's headlight. 
• The speedometer, temperature, battery, and oil gauges are often lit by lights controlled by the dimmer switch. 
• Some cars also have a third dimmer switch which controls the brightness of in-cabin lights. 
• A dimmer switch may be a button or knob mounted on the dashboard or center console.

Have a look at the working of car turn signal & dimmer:

When the turn signal lever is activated in either direction, a circuit is completed that allows power to flow to the front and rear turn signal lights on the selected side. When the signal lights are turned on, they are not illuminated constantly. They flash in a rhythmic pattern because of a flasher unit. 

The headlight dimmer switch controls two separate circuits. When the normal lights are turned on, the dimmer sends a small current to an electric switch called a relay. This current closes the switch, turning on the normal headlights. When the dimmer switch is turned to high beams, it triggers a different relay, turning on the bright high beam headlamps. The normal driving lights are used for parking lights, only with an added resistor to dim the light.

Have a look at the common car turn signal and dimmer problems:

• Problems can occur in any wiring connector. 
• Lights not working due to loosely fitted connector, or water in the connector, plug in connector bend or broken, wire not crimped properly in the lug, low quality of connector used, the connector of the wrong size used, broken wire in connector, rusty lug in the connector. 
• The fuse is an incorrect amperage rating due to which the fuse gets blown. 
• Devices or lights on the circuit can pull too much power, causing the fuse to blow. 
• The vehicle might have a loose electrical connection. 
• A blown bulb will cause problems. 
• Overheat wire due to improper gauge of wire. 
• Socket not clamped properly. 
• Negative wire not connected or loose with the body, flasher unit faulty are some of the problems.

Keen to know about the procedure of changing the Turn Signal & Dimmer Switch? Well, we have simplified the entire procedure for you:

Steps of changing turn signal switch:

Step 1

Remove the negative cable from the battery. Remove the steering column plastic trim to gain access to the turn signal switch. Unbolt the turn signal switch keeping screws. 

Step 2

Disconnect the turn signal switch from the wiring harness. Remove the turn signal switch from the vehicle. Install a new turn signal switch. 

Step 3

Connect the new turn signal switch to the wiring harness. Tighten the turn signal switch retaining screws. 

Step 4

Reinstall the plastic steering column trim pieces. Reconnect the negative battery cable. Check the vehicle to verify the repairs made to the turn signal switch.

Steps of changing Dimmer Switch:

Step 1

The first step is to disconnect the battery, as installing a dimmer switch will require going into the electrical system. Disconnect the negative wire from the battery by loosening the retaining bolt on the battery grounding wire. Make sure the ground cable is kept away from the battery so it does not come into contact with it. Allow the power to drain from the wires for 10 minutes.

Step 2

The old light switch must be removed before the new dimmer switch is installed. Find the interior light switch. Depending on the vehicle, the placement will change. It could be hidden beneath the dash, on the floorboard, or the steering column. All the nuts that need to be loosened and removed will be easier to remove with needle-nose pliers.

Step 3

If you already have a wired connection, this should be quite simple. The new switch should come with a wire connector already installed, so all you have to do now is connect it to the old wiring connector in your car. These can be simply purchased at a local vehicle repair shop if you do not have a wiring connection.

Step 4

If you're not sure which wires to connect to what, you'll need to test them first. Set the dimmer switch to the lowest possible level. There will be an in-wire, out-wire, and grounding wire. With a neon tester, tap the lights.

Step 5

Connect the wires coming from the automobile to the wires coming from the switch. The grounding wire is usually green. Connect it to a grounding source nearby. Then check the rest of the cables. The in-wire is the one that makes your lights glow. Connect the cables as needed.
