It boasts a brightness that is 400% improved compared to traditional halogen bulbs, thanks to its 54 pieces of 4014-SMD LED chips that provide 360° high luminous efficiency. This ensures excellent visibility with a color temperature of 6000K, delivering crisp white light for safer driving conditions, especially when reversing. Each bulb consumes only 5.5 watts, making it energy efficient by using just a quarter of the power required by conventional bulbs while being four times brighter.

The built-in smart IC driver ensures a constant current and prevents radio interference, with instant-on capability that requires no warm-up time. Additionally, the bulbs feature an electroplating process housing that enhances oxidation resistance and reduces heat production, ensuring a longer lifespan. The design of these bulbs is compact and comparable to OEM bulbs, making them easy to fit into various sockets without polarity issues. However, it is important to note that these bulbs are not compatible with the reverse lights of the 2018-2022 F150 models, so checking vehicle compatibility is crucial.
