Product Specifications

The W5WNA 12V 5W halogen lamp, featuring Natural Amber color and a W2.1×9.5d base, is a low-voltage dedicated light source suitable for vehicle signal and identification lighting, often used as a color-equivalent alternative to the WY5W model. In the model designation, W5W corresponds to the core electrical specifications of 12V and 5W, NA is the abbreviation for Natural Amber, specifically referring to the natural amber light effect; W2.1×9.5d is the standard for the pin-type base, where "W2.1" indicates the pin width is 2.1 millimeters, and "9.5d" indicates the pin depth (length) is 9.5 millimeters. It adopts a universal snap-on pin structure, compatible with standardized slot lamp holders, enabling installation without welding via direct plugging and unplugging for easy replacement.

Adopting halogen cycle technology, this lamp slows down tungsten filament wear effectively. Compared with ordinary colored incandescent lamps, it has higher luminous efficiency and better color fastness. The warm orange hue of natural amber (color temperature approximately 2200K–2600K) offers both warning performance and visual comfort, with a color rendering index meeting the requirements of signal lighting. The 12V low-voltage power supply ensures high safety, making it suitable for enclosed and easily accessible scenarios such as automobiles. During use, it should be matched with a 12V DC or regulated AC power supply to avoid overvoltage; do not touch the glass tube during installation or replacement to prevent local overheating caused by fingerprint grease, which may shorten the service life. It is widely used in car side marker lights, position lights, turn signal auxiliary lights, and industrial warning lights.
