Interior LED bulbs in the Tesla Model Y are a size-code exercise first and a CANbus exercise second. Get the bulb code right (194, T10, festoon 31 or 36 or 42 mm, W5W or C5W), then decide whether CANbus-decoded bulbs are worth the small extra outlay given that this car is already running factory LEDs.
Five things to know before you buy LED interior lights for the Tesla Model Y
- Bulb size code first Pop a bulb out of the Tesla Model Y and read the code printed on the metal cap before shopping, 194, T10, festoon length in millimetres.
- CANbus sensitivity by brand This car is already running factory LEDs. Choose CANbus-ready bulbs if there is any doubt.
- Colour temperature choice 4000-5000K neutral white for reading; 6000K daylight-white for maximum brightness; 3000K warm-white if the goal is a matching yellow look.
- Swap the whole cabin in one go Mixing 6000K LEDs with 3000K incandescents makes the older bulb look broken. Do the whole set together.
- Cover every fitting A complete kit should include dome, map, vanity, boot and glovebox, not just the two obvious ones.
Frequently asked questions
Are these bulbs CANbus-sensitive on the Tesla Model Y?
This car is already running factory LEDs. The whole cabin already runs LEDs from the factory, so aftermarket kits here are brightness or colour-temperature upgrades rather than incandescent-to-LED replacements.
What colour temperature works best inside a car?
Around 4000-5000K neutral white is the sweet spot for reading a map or a phone screen without eye fatigue. 6000K daylight-white is brighter but harsher; 3000K warm-white can be too dim on cheap bulbs.
