# Tesla Model Y Headlight and Bulb Sizes

The specification is not the same across every year we cover, the table below shows exactly where it changes.

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

| Model years | Low beam | High beam | Fog |
| --- | --- | --- | --- |
| [2025](https://whichcarparts.com/cars/tesla/model-y/2025/bulbs) | LED (sealed assembly with full-width light bar DRL, no user-replaceable bulbs) | LED (sealed assembly) | N/A |
| [2020-2024](https://whichcarparts.com/cars/tesla/model-y/2020-2024/bulbs) | LED (sealed assembly, no user-replaceable bulb) | LED (sealed assembly; Matrix-capable headlights on late 2023+ builds) | LED (where equipped) |

## Full specifications by generation

The headlight bulbs on a Tesla Model Y 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 Y headlight bulbs: common questions

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

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

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

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.
