With up to 380% more brightness than standard halogen bulbs, a crisp 6000 K cool white beam and simple plug-and-play installation, these LED bulbs help improve night-time visibility without major wiring changes.\u003c\/p\u003e\n\u003cp\u003eEach bulb delivers approximately 1800 lm on low beam and 2500 lm on high beam, giving drivers a clearer view of roads, signs, hazards and work areas. The LG5017 is suitable for 9–16 V DC systems and is supplied as a pair for left and right headlamp replacement.\u003c\/p\u003e\n\u003ch2\u003eH4 LED Headlight Bulb Upgrade\u003c\/h2\u003e\n\u003cp\u003eThe LG5017 is built for drivers who want a brighter, cleaner beam than standard halogen lighting. It is suitable for vehicles with H4 bulb fittings where the same bulb provides both low beam and high beam functions.\u003c\/p\u003e\n\u003cp\u003eThe 6000 K light colour gives a modern white output that improves visual contrast compared with older yellow halogen bulbs, helping reduce eye strain during night driving, early starts and poor weather conditions.\u003c\/p\u003e\n\u003ch2\u003eStrong Low Beam and High Beam Output\u003c\/h2\u003e\n\u003cp\u003eEach bulb produces approximately 1800 lumens on low beam and 2500 lumens on high beam, with a tolerance of ±10%. This provides useful forward visibility for unlit roads, rural routes, industrial sites, yards and service vehicles that operate in low-light conditions.\u003c\/p\u003e\n\u003cp\u003eThe improved brightness helps drivers identify obstacles, road markings and signs earlier, supporting safer and more confident driving.\u003c\/p\u003e\n\u003ch2\u003eAdvanced Cooling and Thermal Control\u003c\/h2\u003e\n\u003cp\u003eThe LG5017 uses a thermal design built around an aluminium shell, a pure copper thermal plate and a dual ball silent cooling fan. This helps move heat away from the LED chips and maintain stable light output during extended use.\u003c\/p\u003e\n\u003cp\u003eAn intelligent temperature control IC monitors heat and adjusts power when necessary, helping protect the LEDs from thermal stress and supporting longer service life.\u003c\/p\u003e\n\u003ch2\u003ePlug-and-Play Installation\u003c\/h2\u003e\n\u003cp\u003eThese H4 LED bulbs are designed for straightforward replacement using the existing H4 connector. In many applications, installation requires no cutting, no extra relays and no complex wiring work.\u003c\/p\u003e\n\u003cp\u003eThe compact cooling design helps the bulbs fit into many standard headlamp housings, making them a practical upgrade for workshops, fleet maintenance teams and vehicle owners.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eH4 LED headlight bulbs supplied as a pair.\u003c\/li\u003e\n\u003cli\u003eDirect replacement style for standard H4 halogen bulbs.\u003c\/li\u003e\n\u003cli\u003eLow beam and high beam functions in one bulb.\u003c\/li\u003e\n\u003cli\u003eUp to 380% brighter than standard halogen bulbs.\u003c\/li\u003e\n\u003cli\u003eApprox. 1800 lm low beam output per bulb.\u003c\/li\u003e\n\u003cli\u003eApprox. 2500 lm high beam output per bulb.\u003c\/li\u003e\n\u003cli\u003e6000 K cool white colour temperature.\u003c\/li\u003e\n\u003cli\u003e9–16 V DC operating range for 12 V vehicle systems.\u003c\/li\u003e\n\u003cli\u003e22 W low beam power consumption.\u003c\/li\u003e\n\u003cli\u003e32 W high beam power consumption.\u003c\/li\u003e\n\u003cli\u003eAluminium shell for heat dissipation.\u003c\/li\u003e\n\u003cli\u003ePure copper thermal plate for fast heat transfer.\u003c\/li\u003e\n\u003cli\u003eDual ball silent cooling fan for active temperature control.\u003c\/li\u003e\n\u003cli\u003eIntelligent temperature control IC to help protect LED performance.\u003c\/li\u003e\n\u003cli\u003ePlug-and-play H4 connector for easier installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eIdeal Applications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePassenger cars with H4 headlamp fittings.\u003c\/li\u003e\n\u003cli\u003eLight commercial vans and service vehicles.\u003c\/li\u003e\n\u003cli\u003eFleet vehicles used for early morning or night driving.\u003c\/li\u003e\n\u003cli\u003eRural vehicles and agricultural support vehicles with 12 V systems.\u003c\/li\u003e\n\u003cli\u003eTrade, construction and workshop vehicles entering poorly lit sites.\u003c\/li\u003e\n\u003cli\u003eVehicle owners upgrading from halogen to a brighter white LED beam.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy Choose the LG5017 H4 LED Bulb Pair?\u003c\/h2\u003e\n\u003cp\u003eThe LG5017 is designed for users who want stronger night visibility, modern white light and simple installation.
