H4/9003 Halogen Headlight Bulb, 4000K Warm White, OEM Replacement, 2 Pack

About this item

• 【Vacuum Precision Optical Blue Film Technology】Engineered with a micron-level optical blue coating, this technology filters the yellowish tint typical of conventional halogen bulbs, producing a whiter, crisper beam output. The coating also acts as a thermal insulator with enhanced UV protection, effectively slowing oxidation, yellowing, and premature aging of the headlight housing. Please note: this bulb delivers an enhanced warm white halogen output — not the cool white appearance of HID lighting
• 【Brighter Output & Extended Lifespan vs. Standard Halogen】Experience a visibly brighter, cleaner 4000K beam at approximately 1,900 lumens — up to 300% brighter than standard halogen bulbs. A reinforced filament and optimized halogen gas fill work together to deliver 1.5–2× the lifespan of conventional bulbs, meaning fewer replacements and more miles of reliable performance
• 【Road Legal & Street Ready】Designed to support safe and compliant road use through a controlled beam pattern, balanced light output, and dependable electrical performance. By maintaining the essential characteristics expected for on-road driving, it delivers responsible illumination for everyday driving conditions
• 【OEM Direct Fit — Installs in 2 Minutes】No modifications, no tools, no hassle. Simply remove your old bulb and plug in the new one for a seamless OEM-fit upgrade. Caution: Avoid touching the glass surface — skin oils can cause uneven heating and reduce bulb lifespan
• 【Verify Fitment Before Purchasing】Use Amazon's Compatibility Tool as a starting point, but for the most accurate results, cross-reference your original bulb number, owner's manual, or VIN.
