Product Specifications

The P27/7WNB is a dual-power focused vehicle warning bulb with a rated voltage of 12V, supporting two working modes of 27W high power and 7W low power. It emits natural blue light and is compatible with the dedicated W3x16q dual-contact wedge base. In the model designation, "P" stands for parabolic reflective structure; the light is directionally focused after being reflected by the inner wall, featuring a long irradiation distance and excellent warning focusing effect. "27/7W" is the core identifier of dual power, which can accurately switch circuits through the dual contacts of the base. "NB" corresponds to Natural Blue, whose light is soft and refreshing, different from ordinary high-brightness blue light, and will not cause glare interference to drivers of other vehicles.

The W3x16q dual-contact base has a precise design, which can strictly distinguish between high and low power circuits, with convenient plug-and-play operation and stable connection, and is compatible with the taillight assemblies of most passenger vehicles. This bulb adopts proven tungsten filament lighting technology. The 27W high-power mode delivers strong brightness, which is mostly used in high-light warning scenarios such as reversing lights and brake lights; the 7W low-power mode has low energy consumption and can be used as the constant-on mode of position lights. The dual-purpose feature simplifies the layout of vehicle lamps, making it a vehicle lighting accessory that balances personalization and practicality.
