PREMIUM 2-PACK SOLUTION: Includes both driver/passenger ballasts + D1S bulbs - no mismatched pairs. Heavy-duty ABS housings (26x15x18cm) resist cracking in extreme temperatures (-40°C to 105°C). 3X lifespan vs. plastic OEM units.
ADVANCED CIRCUIT PROTECTION: Sealed potting compound shields electronics from moisture/vibration. Integrated safeguards prevent short-circuiting, voltage spikes, and bulb flickering. Maintains stable 35W output for DOT-compliant beam patterns.
INSTALLATION CRITICALS: Professional installation recommended. While plug-and-play, some models require HID system recalibration (e.g., Volvo S80). Disconnect battery - 35W systems carry lethal voltage!
