For the 2000 BMW X5, the low-beam headlight uses a D2S bulb, while the high beam uses 9005. The supplied fitment data does not identify a projector or non-projector headlight variation, so verify the bulb and headlamp housing before ordering.
Front fog lights may use either H3 or H3C. Front turn signals and parking lights also have two listed options: 3457 or 3457A. Compare the removed bulb with the original to select the correct version.
Other notable exterior fitments include 7506 for reverse lights, 7506R for brake and tail lights, 7528 for rear side markers, and an LED center stop light. Rear turn signals may use 7506 or 7507, also requiring comparison with the original.
Interior applications include 6418 for the glove box and interior light, 6486X for the dome light, and 2886X for the map, trunk, and door-mirror lights. Vanity lights may use 6411 or 6428.
