For the 2012 Volkswagen Tiguan, the low-beam headlight uses a D3S bulb. High-beam fitment is listed as either H15 or D3S, so verify the headlight assembly before ordering. The daytime running light also varies by headlight type: H15 with halogen headlights and LED with HID headlights.
Parking light fitment follows the same configuration split. Halogen-equipped models use 2825 or 98 bulbs, while HID-equipped models use LED lighting. Other useful exterior applications include a 7507 front turn signal, 7506 rear turn signal, 921 tail and reverse lights, and 7506R brake lights. The center stop light is LED.
Interior and auxiliary applications include 6418 for the license plate and vanity lights, 2821 for the front side marker, step, courtesy, and glove-box lights, and 6411 or 6428 for the trunk light. Check the existing bulb and headlight type when multiple options are listed.
