LED Interior Lights for Toyota Corolla & Camry — Bulb Sizes & Install Guide
The Corolla and Camry are two of the most popular cars on the road, and both leave the factory with the same dim yellow interior bulbs. Swapping to LED is one of the easiest upgrades you can do, and the difference at night is immediate.
This guide covers the Corolla (E140, E170) and Camry (XV40, XV50), including the exact bulb sizes, installation steps, and what to watch for on Toyota's electrical system.
Toyota Corolla and Camry bulb sizes
| Position | Corolla E140/E170 | Camry XV40/XV50 |
|---|---|---|
| Dome light | 31mm festoon | 42mm festoon |
| Map / reading lights | T10 (W5W) | T10 (W5W) |
| Trunk light | 31mm festoon | T10 (W5W) |
| License plate lights | T10 (W5W) | T10 (W5W) |
| Footwell lights | n/a (some trims) | T10 (W5W) |
Check your trim level. Toyota offered different interior lighting packages across trims, so a base Corolla may not have footwell lights while a higher trim does. Check what is actually in your car before ordering a full kit.
Will LED bulbs cause problems on a Toyota?
Generally no, and that is one of the nice things about Toyota. Most Corolla and Camry models do not aggressively monitor interior bulb resistance the way BMW and Mercedes do.
A few higher-spec Camry models do have bulb-out detection on some circuits, and if you get a flicker or a warning, error-free CANBUS bulbs solve it. But for most Corolla and Camry owners, standard LED bulbs work without any issues.
Step-by-step install
- Pop the lens covers off with a plastic trim tool or a thin card.
- Pull the old halogens out. Rock them side to side if they are stuck.
- Insert the LEDs. Plug and play, no wiring.
- Test each light. If one doesn't light, flip it 180 degrees. LED bulbs are polarity-sensitive.
- Snap the covers back on.
The whole job takes about fifteen minutes on a Corolla or Camry. The dome and map light covers come off easily, and the trunk light is straightforward.
What color temperature suits a Toyota?
6000K is the most popular choice and matches the modern white look. If you want a softer, more factory appearance, 5000K is a good middle ground. Avoid anything above 6500K in the cabin, it starts to look blue and harsh.
Frequently asked questions
Do I need to disconnect the battery? No. Interior bulb swaps are low voltage and safe to do with the lights switched off.
Why is one LED not working after install? Polarity. Pull it out, rotate it 180 degrees, and push it back in. This fixes it almost every time.
Can I mix LED and halogen bulbs? You can, but the mixed yellow and white light looks inconsistent. Do the whole interior at once for a clean result.
The bottom line
The Corolla and Camry are some of the easiest cars to upgrade to LED interior lighting. No complicated CANBUS issues on most models, fifteen minutes of work, and a completely different cabin at night.
