Through extensive testing, Marsauto has eliminated the need for additional resistors, providing an advanced turn signal bulb that eliminates worries about hyper flash.

The latest cooling system includes a 15,000 RPM silent fan and heat sink holes in the lamp body, effectively doubling heat dissipation and ensuring a longer lifespan of up to 50,000 hours. This thoughtful heat dissipation design maintains the bulb at a reasonable temperature, extending its longevity.
- [Dual Color Switchback] The Marsauto 7443 switchback LED bulb with resistor offers a unique dual-color feature. It emits a cool white light for parking lights or daytime running lights (DRL), while displaying an amber yellow light for turn signal lights. This distinct color combination enhances visibility and adds a stylish touch to your vehicle's lighting.
- [Compatible Bulb Models] These bulbs are compatible with various bulb models, including 7443, 7443A, 7443LL, 7443NA, 7443SRCK, 7444, 7444NA, 7444LL, W21W, and T20. They serve as an upgrade for multiple functions such as front/rear turn signal lights, tail lights, brake lights bulbs, side marker lights, corner lights and blinker lights, providing a brighter mode and enhanced performance.
- [Plug & Play, Sockets Support] These bulbs are designed to fit both US standard sockets and CK sockets. They are specifically engineered to directly replace factory halogen lamps without any modifications or the need for extra decoders. With the Marsauto 7443 LED bulbs, you can easily replace your switchback turn signal bulbs within 5 minutes, ensuring a perfect fit into your housing based on the OEM halogen bulb socket.
