13 best automotive dimmer switches

Automotive dimmer switches are components found in vehicles that allow the driver to adjust the brightness of the interior lighting, particularly the instrument cluster lights and dashboard illumination. These switches are considered part of the interior switches and trim category and play a crucial role in enhancing visibility and comfort for the driver, especially during nighttime driving.

Here are key points about automotive dimmer switches:

  1. Functionality: The primary function of an automotive dimmer switch is to control the intensity of the interior lighting. By adjusting the switch, the driver can increase or decrease the brightness of dashboard lights and other interior illumination.

  2. Location: Dimmer switches are typically located on or near the dashboard of the vehicle, within easy reach of the driver. The exact placement may vary among different vehicle models.

  3. Compatibility: Dimmer switches are designed to be compatible with the specific electrical system and interior lighting configuration of a particular vehicle make and model.

  4. Construction: These switches are constructed with durability in mind, given their frequent use. They often have a rotary or slide design, allowing for easy and intuitive adjustment.

  5. Integration with Other Systems: In modern vehicles, dimmer switches may be integrated with other systems, such as the headlight switch or the overall lighting control system.This integration enables a seamless adjustment of both exterior and interior lighting.

  6. Replacement Parts: Like other interior switches, dimmer switches may need replacement over time due to wear and tear. Replacement dimmer switches are available through automotive parts suppliers and dealerships.

  7. Electrical Connections: Dimmer switches are electrical components, and their installation involves connecting them to the vehicle's electrical system. It's crucial to follow the manufacturer's guidelines during replacement or installation.

  8. Enhanced Driving Comfort: The ability to adjust interior lighting intensity contributes to driving comfort, as it allows the driver to customize the lighting to suit their preferences and driving conditions.

  9. Maintenance: While dimmer switches are relatively durable, periodic maintenance and checks are advisable to ensure proper functionality. This is especially important if the driver notices any issues with the interior lighting.

  10. Aftermarket Options: In addition to OEM (Original Equipment Manufacturer) replacements, there are aftermarket dimmer switches available, providing alternatives or upgrades for those looking to enhance or customize their vehicle's interior lighting controls.

In summary, automotive dimmer switches are integral components that enable drivers to control the brightness of interior lighting. They contribute to driving safety and comfort, especially during low-light conditions, and are an essential part of a vehicle's interior switches and trim system.

User questions & answers

Question: I bought this, installed it, and there's no backlighting like the factory light switch, is the something special to do to make this backlighting work
Answer: ....not particularly. It’s best to cut the rotten, rusty stuff away, sand, add rust remover / preventer, use a self-etching primer (2 coats), use a spray undercoating, trim the rocker panel (product sold above) to fit the hole and then install using your preferred method of either riveting or welding... slap some BONDO on there, sand and paint.
Question: What color does it light up
Answer: These are slip on rockers. I bought these because it was said these were weld on. Not the case

Question: My instruments light either are very dim or light up not at all. Will this new switch remedythe problem
Answer: This is not a momentary switch. It switches from one circuit (low beam) to another circuit (high beam). you need a momentary switch for a horn.
Question: Does this switch allow you to twist to the left and release to turn off the DRL's
Answer: It fit my 1968 Mustang. Not sure about a 65 T-bird. But I'm guessing all Ford products made during the mid to late 60's used the same switch.
Question: How much for switch with LED
Answer: Since I Don't Make Them I Really Can't Say.Since Electric Does Not Go Through Plastic I Would Assume Some Parts Have Metal On Them. That Is My 2 Cents Worth.But Like i Said That Is My Opinion.Just Asking why Do You Ask? Thanks For Question Regards David
Question: Are the illuminated indicators on this switch white in color when illuminated, or do the bulbs behind the face plate give off a blue/green light
Answer: I ordered these for my husband to put on his truck. He said once the panels go on the cab corner will automatically go up about 2 inches.

User questions & answers

Question: what gauge wire is used in the dimmer switch? thanks
Answer: this is a PWM dimmer. work's great for led's
Question: Can it dim Landscap lighting hooked up to a transformer 12v
Answer: Yes it works just fine. All you need is a second switch that is SPDT and you wire the 'pole' sourcing from your + and the two 'pole' locations feed one to the dimmers red and the other to the 3way sw 1/p terminal. American Tech makes one - model AH-SWI-02-x where the X is 5 for black and 1 for white. wiring diagrams is at this link on the manufactures web site. https://www.atcomp.com/wp-content/uploads/2018/08/12V-3WAY-DIM.pdf Hope that helps folks
Question: Does this dimmer have an off position
Answer: A) If you have an existing switch: The two wires on the old switch are not really positive and negative. One is +12 volt power from the battery, and the other is going to the light. If you look inside the wall, you will likely find that each of the two coloured wires is paired with a white wire and those two white wires are connected together. Those white wires are the negative, and the place to connect the negative (neutral) wire from the new dimmer switch. After disconnecting the old switch, use a volt meter or a test light to determine which of the coloured wires is live - that will be the one coming from the battery. Connect that to the +12 volt side of the new dimmer. Connect the other coloured wire to the load side of the dimmer. B) If there is no existing switch, just a light: Disconnect the positive wire from the light and connect it to the +12v wire of the dimmer. Connect the negative wire of the dimmer to the existing negative wires of the light. Connect the load wire of the dimmer to the open positive wire of the light.
Question: My landscape lighting transformer has an output of 12v ac. Will this dimmer work with that voltage
Answer: I installed my light bar and headlamp dimmer switch. It works beautifully! Ensure you install a relay.
