🧭 How to Choose the Best Interior LED Lights for Your Tesla Model 3
Bulb replacement vs ambient kit
Bulb replacements swap the Model 3's dome, cargo, and trunk bulbs for brighter white LEDs, plug-and-play. Ambient kits add color-changing strips or fiber and require routing wires. Choose based on whether you want cleaner factory light or a custom cabin glow to complement Tesla's ambient strip.
Getting the right bulb size
Most Model 3 dome and reading lights use a 31mm festoon bulb, while trunk, frunk, and glovebox lights use a 194/T10 wedge. Pull one bulb to confirm, or buy a multi-size kit to cover every socket.
App/RGB control and install difficulty
RGB kits like Govee power easily from the Model 3's USB ports, but hiding strips under trim and running clean wire takes time. Keep all wiring clear of airbag areas under the dash. Bulb swaps are a ten-minute job.
❓ Frequently Asked Questions
What bulb size does the Tesla Model 3 dome light use?
Most Model 3 dome and reading lights use a 31mm festoon bulb, while trunk and frunk lights use a 194/T10 wedge. Confirm by pulling a bulb before ordering.
Will LED interior bulbs affect the Model 3's software or warnings?
No. Interior lights are simple bulbs and are not monitored by the car's software, so swapping to LED will not trigger any error or affect other systems.
Can I add ambient lighting to match the Model 3's factory strip?
Yes. App-controlled RGB kits let you dial in a color close to Tesla's ambient strip and power from the cabin USB ports. Plan the install time to hide wires and keep them clear of airbag zones.
