H4 LED Headlight Bulb Canbus Error Free,270W/Set Ultra Bright 6500K White 40000LM 700% Brighter,IP68 Waterproof Copper Pipes Cooling Headlamp Hi/Lo Beam 360 Adjustable Bulbs 12 24V

【Ultra-Bright Automotive LED Lighting】Supports 12–24V operating voltage with 270W high power; delivers high-brightness 6500K cool white light—700%–900% brighter than stock halogen bulbs. Equipped with 30 LED chips, it offers strong penetration, uniform road coverage, full white light output, long-range projection, and stable performance. 【Smart Circuitry & Hardware】Features a built-in smart IC driver and EMC decoding chip with CAN-bus support. Includes overload protection, smart temperature control, and anti-interference capabilities to ensure stable output and minimize error warnings or flickering. Compatible with 99% of vehicle models on the market, including sedans, SUVs, and trucks. 【Rapid Heat Dissipation (Copper + Aluminum + Fan)】Uses a high-speed, quiet turbo fan (12,000–18,000 RPM) combined with a hollowed-out base to accelerate airflow and quickly dissipate heat from the chips. Aviation-grade aluminum paired with dual high-conductivity copper heat pipes rapidly lowers the bulb temperature, effectively solving heat conduction and dissipation issues in tight spaces. 【Dual Copper Heat Pipes & Premium Components】Utilizes automotive-grade CSP/3570 LED chips, an ultra-thin copper substrate, and an aviation-grade aluminum alloy housing. Dual copper heat pipes ensure efficient heat transfer and a robust thermal base. IP68 waterproof and dustproof rating ensures reliable performance in harsh conditions like rain or fog. 【Ultra-Simple Installation】Plug-and-play design with model-specific connectors; no rewiring required—simply replace the old bulb. If the bulb doesn't light up, simply flip the plug and reconnect. The base supports 360° rotation for fine-tuning to achieve the optimal beam pattern. 【Perfect Beam Pattern】The beam pattern replicates the original halogen bulb 1:1, providing uniform road coverage and a precise cut-off line (low on the left, high on the right) to ensure oncoming traffic remains undisturbed. It prevents glare and blinding other drivers, ensuring safety. Lifespan of 60,000–100,000 hours. 【After-Sales Service】Includes a 2-year warranty; please contact us regarding any shipping damage or manufacturing defects.
