Why Do You Need Lasfit LED D2 Series Red Tail Lights?

1. Powerful CANBUS Decoding, No Hyper Flash
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. High-Brightness for Noticeable Braking & Turning
With 2400 lumens per bulb, these red LED rear turn signal/brake/tail light bulbs deliver a brighter, faster, and more noticeable warning signal, helping drivers behind you react sooner when you brake or signal.
3. 360° Soft Red Output, No Harsh Hot Spots
The D2 Series simulates the factory halogen filament position with side-mounted and top-mounted LED chips, creating true 360° red LED light output for smoother, fuller tail light housing coverage with fewer dark spots and less glare.
4. Advanced Cooling for Long-Lasting Performance
Premium automotive-grade LED chips, an aviation-grade aluminum body, and optimized cooling help reduce heat buildup, maintain stable brightness, and support longer-lasting performance for daily brake light, tail light, and turn signal use.
5. Plug & Play LED Bulb Upgrade
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.
