The 2020 Lexus RX 350 uses LED low-beam and high-beam headlights. The supplied fitment data does not list a replaceable halogen bulb size for either headlight function, so confirm the original lamp assembly before ordering a replacement.
Front fog lights are also LED. Depending on the vehicle’s lighting configuration, the front turn signal and parking light may use a 7444NA bulb or LED lighting. Front side markers may similarly be fitted with a 168NA bulb or LEDs.
- Rear turn signal: 7440A or LED, depending on configuration
- Reverse light: 921
- Brake, center stop, tail, rear side marker, cornering, license plate, and dome lights: LED
- Glove-box and map lighting: LED
- Interior and trunk lights: 168
Because several exterior functions are available as either LED or replaceable-bulb setups, compare the existing socket and lamp assembly with these listings before purchasing.
