For the 2015 Tesla Model S, headlight bulb fitment depends on the headlight type installed. Models with halogen headlights use a 9005 bulb for both the low beam and high beam.
Models equipped with HID headlights use a D3S bulb for both the low beam and high beam. Confirm whether the vehicle has halogen or HID headlights before ordering, since these applications are not interchangeable.
The fog lights, front and rear turn signals, reverse lights, brake lights, center stop light, daytime running lights, parking lights, front and rear side markers, and tail lights are listed as LED. The license plate light uses a 6418 bulb.
