Lasfit Brand-New D2 Series | The Best Can-Bus Decoding Solution for Rear Turn Signal/Brake/Tail Lights

The all-new Lasfit D2 Series upgraded LED rear turn signal/brake/tail lights feature powerful CANBUS decoding, optimized red signal control, and long-lasting reliability. Combining automotive-grade LED chips, a low-voltage linear driving solution, and an advanced cooling system, the D2 Series delivers brighter, more noticeable illumination without glare, while providing a true plug-and-play installation experience.

1. Halogen-Like Power for Maximum Compatibility

Designed to closely match the power consumption of factory halogen bulbs, the D2 Series provides strong CANBUS decoding to eliminate hyper flash and dashboard errors. The low-voltage linear driver ensures stable current output with minimal heat, greatly reducing the risk of radio noise, reverse camera interference, or system conflicts.

2. Optimized 360° Soft & Uniform Beam Pattern

By accurately simulating the halogen filament structure, the D2 Series bulbs deliver true 360-degree illumination. Side-mounted, horizontally positioned high-output 3570 LED chips and top-mounted 1860 chips work together with a frosted diffuser to evenly distribute light, reducing glare while maintaining excellent visibility.

3. High-Brightness Output with Automotive-Grade LED Chips

Delivering up to 2400 lumens per bulb, the D2 Series uses premium automotive LED chips (1860 × 3 × 40 Mil + 3570 × 12 × 45 Mil). The larger emitting surface improves brightness, heat distribution, and durability, ensuring consistent performance and extended lifespan.

4. Advanced Cooling for Long-Lasting Performance

Built with an aviation-grade aluminum body and an optimized internal structure, the bulb supports enhanced active and passive cooling. Improved airflow and heat dissipation help maintain consistent brightness over time.

5. True Plug & Play, Non-Polarity Design

Featuring a true non-polarity structure and halogen-sized form factor, the D2 Series installs easily in all most vehicles without rewiring, external resistors, or additional decoders—simply plug it in and go.
