Standard for 12 Volt Cigarette Lighters, Power Outlets, and Accessory Plugs
This standard is intended to cover cigar or cigarette lighters as well as power outlets based on the form and dimensions of
the cigar lighter, and accessory plugs for use in these devices. Components covered herein are designed to work in
nominal 12 VDC systems. This standard is a full performance specification. It includes dimensional and operational
parameters as well as performance characteristics which must be met when submitting a cigar lighter assembly, power
outlet assembly, or plug for production approval. This standard constitutes an acceptance specification for these devices.
This standard covers the operational, reliability, durability, acceptance, and testing requirements for a cigar lighter (also
referred to as just "lighter") for installation in the passenger compartment of production vehicles. This standard covers
power outlets that are based on the form and dimensions of the lighter receptacle intended for installation in the
passenger compartment of production vehicles. This standard also covers plugs designed for insertion into the power
outlet. Associated components supplied as part of, or with the lighter or outlet are also covered. Additional requirements
may be added for these devices when mounted outside the passenger compartment of production vehicles.
Testing shall be done on part families (i.e. lighter receptacles and related knob-elements), as opposed to separate
piece-parts, as directed by the appropriate purchasing agreement. Lighter knob-elements and lighter receptacles are not
intended to be interchangeable when manufactured by different suppliers.
Rationale: This revision to the specification incorporates dimensional and performance additions to accommodate known and
anticipated usages and installations, and adds more detailed testing requirements. It adds requirements for power outlets
based on the lighter receptacle. It also adds requirements for aftermarket devices and plugs designed to be inserted into
the lighter or power outlet receptacle. This revision is also intended to supersede SAE/USCAR-4, November 1997.
