Built for off-road enthusiasts and performance-minded drivers who want to ditch aging HID ballasts and xenon bulbs, the D1 Pro Series combines an extreme LED chipset with an all-metal housing and a 2 mm solid copper thermodynamic core that keeps operating temps locked at just 46.1°C. Wide 12-24V input voltage compatibility makes these a versatile upgrade across a broad range of vehicles and applications.\u003c\/p\u003e\n\n\u003cp\u003eRunning at 70W per set, the D1 Pro's IC thermal controller pairs with a high-speed smart fan to actively pull heat away from the diodes — extending LED life and maintaining consistent output even under sustained use. The fully rotatable collar lets you fine-tune the beam pattern for perfect cutoff alignment in projector housings (the standard housing type for D1S \/ D1R applications), while built-in reverse polarity protection means you can't wire it wrong. The integrated EMI filter keeps your radio, GPS, and CB completely static-free. Backed by a 3-year warranty, this is the D1S \/ D1R LED upgrade that serious enthusiasts have been waiting for.\u003c\/p\u003e\n\n\u003cp\u003eThe D1 Pro Series is compatible with any vehicle running a D1S or D1R HID socket — a fitment found on a wide range of European and domestic luxury vehicles, performance cars, and trucks equipped with factory HID projector headlights. Installation replaces the OEM HID bulb directly; in most cases the factory ballast is bypassed or removed. For vehicles with CANBUS systems, a CANBUS decoder may be required to prevent error codes.
