Tap any bulb size to see it on Amazon. Trims and mid-year changes can differ, so pull the old bulb and match the number on its base before you order.

Which bulb should I buy?

  • Just need it working again? Buy the standard halogen in the same size. It's cheap, it's legal everywhere, and it takes five minutes.
  • Want to see better at night without messing with anything? Step up to a brighter halogen. Same plug, more light, no wiring.
  • Want the white, modern look? Go LED. Great for fog, reverse, plate and interior lights. For headlights, LED bulbs in a housing built for halogen can throw glare, so aim them after you install and check your state's rules before running them on the street.

Our picks by bulb size

D1S (headlight high beam and low beam)

194 / 2825 (license plate light, parking light, stepwell light and more)

For brake lights and turn signals, match the LED color to the lens: red behind a red lens, amber for turn signals.
