2019 Tesla Model 3 bulb fitment is LED throughout the supplied fitment data. Both the low-beam and high-beam headlights use LED lighting, so no replaceable halogen or HID bulb size is listed for either function.
The fog lights, daytime running lights, front and rear turn signals, and front and rear side markers are also LED. Exterior lighting remains LED for the brake lights, center high-mounted stop light, tail lights, reverse lights, parking lights, and license-plate lights.
- Headlights: LED low beam and LED high beam
- Fog lights: LED
- Signal and marker lights: LED front and rear
- Rear lighting: LED brake, center stop, tail, and reverse lights
- Interior lighting: LED dome, glove-box, interior, and trunk lights
No projector-versus-non-projector or other configuration-specific headlight variation is identified in the supplied data. Confirm the vehicle’s original lighting assembly before ordering replacement parts, since this listing provides LED fitment rather than a conventional bulb code.
