Names you will see on the package
Manuals print the base number plus maker suffixes. The suffixes seen for this bulb are 7440. Suffixes such as NA (amber), K or LL (long life) change the colour or life rating, not the base and fit; an amber NA bulb should be replaced with another amber bulb. Some manuals print an equivalent name alongside it: W21W. Those pairings come from the manual itself.
Before you buy
Bulb numbers change with trim and lighting package: a car with LED headlights has no 7440 in that position even when the halogen version does. Open your model year and match the row for your trim, then check the number on the old bulb's base. Halogen capsules (H-series and 9000-series) should be handled by the base, not the glass.
