Product Specifications

The PY27/7W 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 amber 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 high warning visibility. "Y" corresponds to amber, emitting striking yellow light with excellent penetration in severe weather. "27/7W" is the core identifier of dual power, enabling precise circuit switching by virtue of the dual contacts of the base.

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 and turn signal 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 for turn signals and hazard warning lights; the 7W low-power mode has low energy consumption and can be used as side marker warning lights. The dual-function integration simplifies lamp configuration, making it a vehicle lighting accessory that balances warning effect and installation convenience.
