Driving with dim or flickering headlights? This MOTOKU HID ballast kit might be exactly what your Chevy needs! Specifically designed for models like the Blazer (2019-2020), Impala (2014-2020), Suburban (2015-2020), Tahoe, and Malibu (2013-2015), this kit replaces those expensive OEM parts without breaking the bank. It comes with everything you need - 2 HID xenon ballast modules, 2 high voltage cables, and 2 D3S bulbs. The compatibility is specific though - for Impala 2018-2020, it works with Osram ballasts and headlight part numbers 84160412/84160413. It replaces part numbers 20928264, 13503432, 13587720, and 13587843 if you're checking against your old parts. Installation is pretty straightforward if you're comfortable with basic car electronics - just make sure to disconnect the battery first! The ballasts provide stable power to your HID bulbs, eliminating that annoying flickering and ensuring consistent bright light output. Perfect for night driving when you need maximum visibility. Much cheaper than dealership parts, and you get the complete set rather than buying pieces separately. Your nighttime drives are about to get a whole lot brighter and safer!
