The reviewer found the plug-and-play fit and integrated anti-flicker circuitry to be the single biggest reason to buy, since they replace common H4651\/H4656 style units and cut installation to about 20 minutes while avoiding flicker or CANbus errors on most vehicles.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDOT Approved:\u003c\/strong\u003e Legal for road use and designed to meet DOT and SAE standards so drivers can upgrade lights without compliance concerns.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug and play installation:\u003c\/strong\u003e Comes with all required parts and H4 9003 HB2 wiring harnesses so most installations take about 20 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh output LEDs:\u003c\/strong\u003e Delivers strong illumination with 3600Lm per piece on high beam and 2800Lm per piece on low beam for a wider, clearer field of view.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for durability:\u003c\/strong\u003e IP67 waterproofing, shock proof design and a pure PC lens make these headlights resistant to scratches and road debris.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated anti-flicker:\u003c\/strong\u003e Anti-flicker circuitry on the board helps prevent flickering or warning lights on modern electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImproved cooling:\u003c\/strong\u003e Aluminum alloy housing and upgraded heat dissipation prolong LED life to an expected long lifespan.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis product is aimed at owners of older trucks and cars that use 4x6 in rectangular headlights, including many Kenworth and Peterbilt models and a wide range of light trucks and SUVs.
