Brighten up your Kia Optima's night driving with this Xentec Slim HID conversion kit! It’s a super slim design that fits 2001–2016 Optima models and can be used for low beams, high beams, or fog lights (you choose during installation). The kit includes 2 bulbs, 2 ballasts, and all accessories for a complete setup. You can pick from a range of bulb colors (like 5000K pure white up to 30000K deep blue) and sizes (9007, H13, etc.) to match your style. At 35W and 5800 lumens, it's way brighter than stock halogens, with options for bi-xenon (high & low) or separate high/low setups. Voltage runs from 9V–16V, and it comes with a 2-year warranty. Perfect for anyone wanting that modern, crisp HID look and better road visibility.
