Engineered for the everyday driver, the K15 LED Headlight Bulbs​ deliver a well-balanced 10,000 lumens per pair​ with a crisp 6000K pure white​ output—bright enough to transform nighttime visibility, yet tuned to avoid blinding oncoming traffic.At the core of the K15 are 12 double-sided high-power CSP chips, providing wide, uniform road coverage without dark spots. The beam pattern follows a 1:1 halogen bulb design, ensuring a precise cutoff line and glare-free illumination for oncoming drivers.Efficient Dual Copper Pipe Cooling:The aviation aluminum alloy shell​ acts as the primary heat sink, while two copper heat pipes​ rapidly transfer thermal energy away from the LED chips. An active turbo fan​ accelerates airflow to maintain optimal operating temperature—ensuring stable brightness over time and a lifespan exceeding 30,000 hours.Simply plug into your existing socket—no modification, no wiring. Install in minutes and drive immediately.Why K15 is the Smart Choice:✅ Balanced 10,000LM Output​ — Clear visibility without excessive glare; ideal for city and highway driving✅ Efficient Dual Copper Cooling​ — Aluminum shell + 2 copper pipes + fan maintains consistent brightness, >30,000hr lifespan✅ Perfect Beam Pattern​ — 1:1 halogen design with precise cutoff; no dazzle to oncoming traffic✅ Smart Power Profile​ — 140W peak startup settling to 110W (H7) / 120W (H4) stable; maximum brightness without overloading your vehicle's electrical system✅ Universal Socket Coverage​ — H7, H4, H13, 9004, 9007, 9005, 9006, 9012, H1, H3, H11, 880✅ Plug-and-Play​ — Direct halogen replacement, installs in minutes
