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.

- Cloudy headlights? New bulbs won't fix a yellowed lens. A replacement housing makes a bigger difference than any bulb: see Acura MDX headlights at NTXGlow.
