For the 2009–2014 Kia Sorento, genuine OEM headlight bulbs include options like the H7 halogen bulb (12V 55W) for low/high beams and the W5W (12V 5W) for parking lights, with part numbers such as L and L. Aftermarket LED upgrades are also available, offering brighter, whiter lighting (e.g., 6000K Xenon white) for improved visibility, with compatibility varying by trim (e.g., LX, EX, SX).
