Description
xUpgrade your signal lighting with the Auxbeam B21 Series 3157 amber LED bulbs. Built with a CANBUS aware design, these bulbs aim to reduce common decoder errors for most vehicles, allowing a smoother upgrade without brittle external resistors.
Key benefits at a glance
- CANBUS-ready with built-in resistor to minimize hyper flash and errors on most vehicles.
- 600% brightness with 28W per bulb: 3500K amber light and 360‑degree coverage for clear signaling.
- Dual brightness modes: dim for parking light or DRL, bright for turn signals; amber-off-amber-off pattern for visibility.
- Robust cooling and durability: IP68 sealing, 12,000 RPM silent fan, copper ring, multiple heat sinks, and a 6063 aluminum housing; up to 60,000 hours.
- Plug-and-play fit: 360-degree illumination, no polarity, no drilling; compatible with many US sockets including 3056/3156/3157 families; note not CK sockets.
Real-world use scenarios
For daily drivers, the brighter amber glow improves signal clarity in both daylight and night conditions. In larger vehicles, the 360-degree illumination helps signals remain visible from side angles during lane changes. For pickup trucks and work use, the built-in resistor and CANBUS logic can reduce common warning issues when upgrading from stock bulbs.
What to know before you install
- Not fit CK sockets: verify your vehicle socket type before purchase to ensure compatibility.
- Some trucks or sensitive models may require external resistors; our team can help identify the right solution for your setup.
- Warranty: 1-year warranty included with all bulbs.
Designed to deliver a strong amber signal with dependable performance, these bulbs are ideal for drivers seeking improved visibility without complicated installation. Expect fast on response, immediate illumination, and broad light dispersion that helps signals read clearly from multiple angles.
