Product Specifications

The HY21W halogen lamp with a rated voltage of 12V, power of 21W, color of amber and base model of BAY9s is a low-voltage functional light source that balances high brightness and signal recognition. HY21W is an industry-specific specification code. The 12V rated voltage is perfectly compatible with the electrical systems of vehicles such as cars and motorcycles. With a high power of 21W, its luminous intensity is far superior to that of low-power products in the same series. Combined with the amber light-filtering design, the light has extremely strong penetration and outstanding visibility in low-visibility weather such as rain, snow and fog.

It is equipped with a BAY9s plug-in base with stable contact performance, which is compatible with special lamp holders. It can be installed and disassembled without professional tools, and is fixed firmly, so it is not prone to poor contact or falling off due to vehicle jolts during driving.

This lamp is widely used in key signal parts of vehicles such as turn signals and warning position lights. It can not only clearly transmit driving intentions, but also improve the safety of vehicle driving, making it an optimal choice for vehicle signal lighting that balances practicality and economy.
