Keep your headlights in working order to protect your safety on the road. Without functioning headlights, your range of visibility at night is limited. Reducing your visibility increases your risk of a dangerous accident. You can replace the headlight assembly on your 2007 Kia Optima in minutes at home with common household tools. Order a headlight assembly from a Kia dealership or auto parts retailer.
