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.
