A cigarette lighter is a heating element you push in, and it pops back out when hot

Your car's cigarette lighter is a metal heating coil inside a plastic or metal housing. When you push it in, it stays depressed while the coil heats up. After about 20 to 30 seconds, a spring pushes it back out. The coil is now hot enough to light a cigarette — or to use as a power outlet for phone chargers and other 12-volt accessories.

When a lighter stops working, the problem is usually the heating element itself, not the socket. The element burns out over time, especially if you use it frequently. Replacing it takes about five minutes and costs between $8 and $25 for the part, depending on your car's make and model.

Key Takeaways

  • A car cigarette lighter is a replaceable heating element that sits inside a socket on your dashboard or center console.
  • You remove the old lighter by pulling it straight out of the socket, then push a new one in until it clicks or seats fully.
  • Replacement lighters are sold by part number at auto parts stores, online retailers, and sometimes at dealerships.
  • If the new lighter does not pop out or heat up, the socket itself may be damaged and will need professional repair.

Locate your lighter socket and test the power

The cigarette lighter socket is usually on the dashboard below the steering wheel, on the center console between the front seats, or sometimes in the armrest. On some vehicles it may be in the rear seat area. Look for a round opening about the size of a quarter, often labeled with a cigarette symbol.

Before you buy a replacement, confirm the socket still has power. Push in the old lighter. If it does not stay depressed or if it pops back out when ready without heating, the socket may be dead. You can also test the socket with a 12-volt test light or by plugging in a 12-volt phone charger — if the charger does not work, the socket has no power and replacing the lighter will not fix it.

Remove the old lighter element

Grasp the lighter housing firmly and pull it straight out of the socket. It should come free with steady pressure — do not twist or rock it side to side, as this can damage the socket contacts. If it is stuck, try wrapping a cloth around it for better grip, or gently wiggle it while pulling.

Once removed, look at the heating coil. It will be blackened or discolored from heat. This is normal wear. Set the old lighter aside; you do not need it anymore.

Find the correct replacement lighter for your vehicle

Cigarette lighters are not universal. You need the part number for your specific car. The easiest way to find it is to search online using your vehicle's year, make, and model plus the words "cigarette lighter replacement." You can also call your car's dealership parts department with your vehicle identification number (VIN) and ask for the lighter part number.

Once you have the part number, you can order from auto parts retailers like AutoZone, O'Reilly, NAPA, or Advance Auto Parts. Many carry them in stock, and some offer same-day pickup. Online retailers like Amazon also stock car lighters. Prices typically range from $8 to $25. If you cannot find your exact part number, bring your old lighter to an auto parts store and staff can often match it by size and shape.

Install the new lighter

Remove the new lighter from its packaging. Inspect the heating coil to make sure it is not damaged. The coil should be intact and the housing should not be cracked or bent.

Hold the lighter housing and insert it straight into the socket. Push it in until you feel it seat fully — you will usually hear or feel a small click when it is seated correctly. The lighter should now be flush with the dashboard or console, not sticking out. Do not force it; if it does not seat smoothly, remove it and check that the coil is aligned with the socket opening.

Test the new lighter

Push the lighter in. It should stay depressed while the heating element warms up. After 20 to 30 seconds, it should pop back out on its own. The coil should be hot — carefully touch the very edge of it with your finger to confirm it is warm (do not grab it; it will be too hot to hold).

If the lighter pops out when ready without staying depressed, or if it does not heat up, the socket may have a power problem or internal damage. In that case, the socket itself will need to be inspected or replaced by a mechanic or dealership, which is a more involved repair.

What to do if the socket is damaged

If you installed a new lighter and it still does not work, the problem is likely inside the socket itself. The contacts may be corroded, the spring may be broken, or the wiring may be disconnected. These issues require opening the dashboard or console, which is beyond a straightforward replacement.

Take your car to a dealership or a mechanic who handles electrical work. Bring your new lighter with you so they know you have already ruled out the heating element. Socket repair or replacement typically costs $50 to $150 in labor, plus the cost of a new socket if needed.

Frequently Asked Questions

Can I use a universal lighter or one from a different car?

Universal lighters exist, but they may not fit your socket properly or may not heat correctly. It is better to use the part number specific to your vehicle. If you cannot find your exact part, an auto parts employee can help you match by size and shape.

What if my car does not have a cigarette lighter?

Newer cars often skip the lighter and use only 12-volt power outlets instead. If your car has a round socket but no lighter came with it, you can purchase one separately and install it the same way. Check your owner's manual to confirm whether your model supports a lighter.

Is the lighter still hot after it pops out?

Yes. The coil reaches around 1,100 degrees Fahrenheit. Always wait a few seconds after it pops out before touching it, and be careful around children and pets. Never leave a popped-out lighter unattended.

Can I replace the lighter myself or do I need a mechanic?

Replacing the lighter element is a straightforward five-minute job you can do yourself with no tools. If the socket has no power or the new lighter does not work, that is when you need a mechanic to diagnose the electrical issue.
