Tesla Model 3 2021 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 2021 Tesla Model 3 by lighting position, so you can match the correct replacement to the exact lamp on the car. Whether you are checking exterior lighting or interior convenience lights, the goal is to make bulb selection easier and reduce guesswork before you buy.
The 2021 Tesla Model 3 uses LED lighting for the listed positions on this page, including the headlight high beam and low beam, fog light, brake light, turn signals, license plate light, daytime running light, tail light, reverse light, and several interior lamps. Because lighting equipment can vary by market and body style, it is always smart to confirm the specific position before ordering.
Fitment can vary by trim, package, and region, so the same 2021 Tesla Model 3 may not use identical lighting hardware in every market. This is especially important when comparing factory LED setups with aftermarket replacements or retrofit kits, since an LED assembly is often not a simple bulb swap. If your car has been modified, or if you are converting from one lighting type to another, check the installed part carefully and compare the connector, housing shape, and mounting style before purchasing. The most reliable approach is to inspect the bulb or lamp assembly already installed in the vehicle and confirm it against the position listed on this page before you order.
