2016 Honda Fit bulb fitment uses a 9003 bulb for both the low-beam and high-beam headlights. The same 9003 size is also listed for the daytime running lights, so verify the existing bulb and socket before ordering replacements.
The front turn signals and parking lights use 7444NA bulbs, while the front side markers use 168NA. At the rear, the turn signals use 7440 bulbs and the reverse lights also use 7440. The brake lights, center stop light, tail lights, and rear side markers are listed as LED rather than replaceable bulb sizes.
