Specification AutomotiveFitType : vehicle_specific_fit AutoPartPosition1 : rear AutoPartPosition2 : front Brand : AINOSEIN Brightness : 4000 lumen BulletPoint1 : MID-MOUNTED TURBO FAN DESIGN. No Top Fan Blockage – Unlike traditional white light bulbs with top-mounted fans, our central cooling ensures 360° unobstructed white light output from the bulb's crown - critical for clear visibility in reverse maneuvers and brake signaling. BulletPoint2 : DUAL-CHIP WHITE LIGHT DOMINANCE. 4000LM High-Intensity White Lighting – The 30W 7535 chip delivers daylight-like clarity for reverse/brake functions, while the 1860 low-power chip reduces nighttime glare by 70%. Paired with our precision-engineered lens, light becomes 20% brighter yet glare-free. BulletPoint3 : HYPER-FLASH PREVENTION SYSTEM. CANBUS-Ready Smart System for 12V – Eliminates white light hyper-flash and dashboard errors in most 3157 socket vehicles (2008-2024). Note: For CANBUS-sensitive models, message us for a free resistor wiring guide. BulletPoint4 : LAB-PROVEN COOLING ENDURANCE. Stable 30W Output Under Stress – The 12000 RPM mid-fan and 20 precision vents work with a 6063 aluminum alloy base (200 W/(m·K)) to prevent overheating. Tested at max power for 168 hours non-stop, the 7535 chip maintained 25W+ stable output with zero melting or burnout. BulletPoint5 : UNIVERSAL FIT & HASSLE-FREE INSTALLATION.
