About this item

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 dual color bulbs can directly alleviate decoding problems. Auxbeam offers 1-year warranty. Note: For few sensitive models such as Silverado and Ram, the included free extra resistors will work.
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 White light. Instant-on response without warm-up time. Highly noticeable when turning. 360° full illumination without dark spot or shadow.
DUAL COLOR FUNCTION: This 3157 switchback led bulb with resistor lights up soft white for parking lights or daytime running lights (DRL), and amber yellow for turn signal lights. Unlike most turn signals flashing "amber-white-amber-white" on the market, the Auxbeam 3157 switch back bulbs flash "amber-off-amber-off", making it easier to see from a distance.
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.
