Tesla Model 3 Headlight and Bulb Sizes

Each row links to the full specification for that generation, including trim-by-trim breakdowns and the part numbers. Where engines within a generation differ, that page separates them.

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.

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.
