The lighter in a car is typically called the cigarette lighter, and the socket it sits in is commonly used today as a 12-volt power outlet for accessories.
Origins and terminology
Historically, the term cigarette lighter referred to a small heating element that protruded from a car’s dashboard. When pressed, the coil heated up and the lighter would pop out, allowing a cigarette to be lit. Over time, the same port came to be used primarily for powering devices, so modern owners often refer to it as a 12V outlet or 12-volt socket—though many still call it the cigarette lighter out of habit.
Below is a quick guide to the terms you may encounter and what they refer to in a contemporary vehicle.
- Cigarette lighter: the actual heating unit inside the lighter that glows hot to light a cigarette; in many newer models it’s largely decorative or repurposed, but the term persists.
- Cigarette lighter socket or 12V socket: the receptacle in the dashboard that holds the lighter or powers accessories.
- 12-volt power outlet: the general label for the electrical port used to power devices like chargers and gadgets; it may be marked as 12V, CIG, or ACC depending on the vehicle.
In practice, these terms overlap: the heater is the lighter, the port is the socket, and the broader concept is the 12V power outlet.
Modern reality: from lighter to power outlet
While many cars still feature a cigarette lighter, its original purpose has largely shifted toward powering devices. Today’s dashboards commonly include USB ports, wireless charging pads, and multiple 12V outlets for accessories such as dash cams, GPS units, portable air compressors, or car vacuums. In electric vehicles, the 12V outlet remains, but a heated cigarette lighter is seldom provided as a dedicated feature. Some models even omit the lighter entirely in favor of more USB-C or USB-A ports.
Here is a snapshot of how the function has evolved in everyday use.
- Physical lighter unit: the classic, coil-heated element that fits into a spring-loaded socket and heats up when pressed.
- 12V socket for devices: the surrounding receptacle used to power or charge compatible accessories via a 12V plug or adapter.
- Adapters and USB charging: many drivers use adapters to convert the 12V outlet to USB ports for smartphones, gps units, and other gear.
The exact configuration varies by vehicle, but the shared thread is the car’s 12-volt electrical system serving multiple functions beyond lighting a cigarette.
Practical tips and common questions
Understanding the terminology can save you a few minutes in the car aisle or when reading the owner’s manual. Here are quick reminders about usage and naming.
- When you hear “cigarette lighter,” think either the heating element or the traditional name for the corresponding socket; in many cars it’s now primarily used as a power outlet.
- If you need to power devices, look for the 12V outlet or a USB charging port; you may require adapters to use standard car chargers.
- In most modern vehicles, the 12V system is designed to support multiple devices up to roughly 10-15 amps, but always check your fuse box and manual for exact limits.
In short, the term you hear depends on the context: the heater is the original “lighter,” while the slot itself is best described as a 12-volt power outlet used for charging and powering accessories.
Summary
The lighter in your car is traditionally called the cigarette lighter, and the corresponding socket is commonly referred to as a cigarette lighter socket or a 12V power outlet. Today, most vehicles use that port primarily to power accessories rather than light cigarettes, with USB ports and other charging options often taking the lead. The terminology may vary slightly by region or model, but the core concept remains a 12-volt electrical supply in the dashboard.
