The 2008 Volkswagen GTI uses a D2S bulb for the low-beam headlight. No high-beam bulb fitment is listed in the supplied data, so verify the original headlamp assembly before ordering a replacement.
Front turn signal fitment depends on the headlight configuration: models with halogen headlights use 1156A, while models with HID headlights use 64136. This distinction is important when selecting front signal bulbs.
