# Tesla Model 3 Headlight and Bulb Sizes

The specification is consistent across every generation we hold data for.

## Has the Tesla Model 3 headlight bulbs specification changed by year?

| Model years | Low beam | High beam | Fog |
| --- | --- | --- | --- |
| [2024-2025](https://whichcarparts.com/cars/tesla/model-3/2024-2025/bulbs) | LED (sealed module, no user-replaceable bulb) | LED (sealed module) | LED (where equipped) |
| [2017-2023](https://whichcarparts.com/cars/tesla/model-3/2017-2023/bulbs) | LED (sealed module, no user-replaceable bulb) | LED (sealed module) | LED (where equipped) |

## Full specifications by generation

The headlight bulbs on a Tesla Model 3 is set by its generation, not its model year, so each generation has one page carrying the complete figures, part numbers and fitment notes for every year it covers.

## Tesla Model 3 headlight bulbs: common questions

### What headlight bulb does a Tesla Model 3 use?

LED (sealed module, no user-replaceable bulb) for the low beam and LED (sealed module) for the high beam. Trims with factory LED or HID projectors use a sealed assembly instead and are not bulb-serviceable.

### What fog light bulb does a Tesla Model 3 take?

LED (where equipped).

### Can you put LED bulbs in a Tesla Model 3?

Physically, yes, LED replacements exist in every common base. Whether they work well depends on the housing: a reflector housing designed around a halogen filament scatters LED output into oncoming traffic instead of down the road. Projector housings tolerate the swap far better. Some vehicles also flag the lower current draw as a bulb-out fault.
