Quick answer: Look up the bulb type and wattage in your owner’s manual: it also says which bulbs you can change yourself and which need a dealer (Toyota owner’s manual). Many bulb bases turn counterclockwise to come out and clockwise to go back in (Toyota). Turn the car and lights off, let the bulb cool, and don’t touch the glass with bare hands (Toyota). Many newer lights are sealed LEDs that a shop must replace (Toyota).
⚠ Safety first:
- Check your owner’s manual first: every car is different. On some cars even the headlights and brake lights are dealer-only (Toyota example).
- Turn the engine off and the lights off, and wait: bulbs get very hot (Toyota).
- Don’t touch the bulb glass with bare hands; use a clean dry cloth (Toyota).
- Use the correct wattage and seat the bulb fully, or you risk heat damage, fire or water in the lamp (Toyota).
- Don’t take apart bulbs, connectors or wiring (Toyota).
Steps: easiest & free first
- Confirm which bulbFREE
Have a friend watch while you press the brake or turn on the lights. - Look it upFREE
Owner’s manual: bulb type, wattage, and whether it’s a DIY bulb (Toyota). - Get accessFREE
Usually from under the hood or inside the trunk/back door. Some need a cover removed; tape a flathead screwdriver tip to avoid scratches (Toyota). - Twist out, swap, twist inFREE
Turn the bulb base counterclockwise, replace the bulb, reinsert and turn clockwise (Toyota). - Test itFREE
Wiggle it gently to make sure it’s secure, then turn the lights on to check (Toyota). - Dealer or shop for LEDs and sealed unitsPRO
If a light is made of LEDs and goes out, the manual may say to have the dealer replace it (Toyota).
⚠ When to call a pro: the light is LED or sealed, the manual lists it as dealer-only, the new bulb still doesn’t work (could be a fuse or wiring), or water is pooled inside the lens (Toyota). Renting a car or using a shared/borrowed car? Call the rental company or owner’s roadside number first. See roadside help & emergency kit.
💡 Prevent it: Walk around the car with the lights on every so often. Also check for open recalls by VIN, which are fixed free (NHTSA).
