Auxbeam 2025 B21Pro Series 3157 Amber Yellow LED Turn Signal Bulbs - CANBUS Error Free, Anti Hyper Flash, Super Bright

About this item

• LATEST 3030Pro CHIPS: Sequencing 32Pcs high brightness 3030pro led chips precisely around each 3157 led bulb. 25W High Power Mode brings 500% brighter Amber Yellow light, and 5W Low Power Mode brings 200% brighter Soft Amber light. Instant-on response without warm-up time. Highly noticeable when turning. 360° full illumination without dark spot or shadow.
• WHY CALL IT PRO: Rather than strong and blinding light from other led bulbs, new anti-glare tech and high saturation color tech are applied to the new led chips, emitting soft but colorful light to avoid blindness to others. Lower operating power design is applied to prolong stabilization time. A pair of extra resistors are included in the package as gifts to help solve more unexpected issues.
• CANBUS ERROR FREE: Super compatible for 99% Vehicles. No hyper flash, no errors, no warning. With built-in 2025 micro resistors, these 3157 amber bulbs can directly alleviate decoding problems. Auxbeam offers 1-year warranty. For some super few sensitive models or if you replace the rear turn signal for Pickup/Truck/Lorry, the extra resistors included should be installed.
• 5-LAYER COOLING SYSTEM: The built-in 2025 stable current IC driver avoids digital or VHF radio signal interference. The latest cooling system - 12,000RPM silent fan + Copper cooling ring + Built-in temp-control chips + Culvert heat sinks + 6063 aviation aluminum lamp body directly doubles heat dissipation, ensuring 20% longer lifespan than other bulbs. IP68 waterproof.
• DUAL BRIGHTNESS: This 3157 amber led bulb with resistor lights up soft amber for parking lights or daytime running lights (DRL), and bright amber yellow for turn signal lights. When used as turn signal bulbs, the 3157 led bulb with built in resistor flash "amber-off-amber-off", making it easier to see from a distance.
