For the 2017 Honda CR-V, headlight bulb fitment depends on the factory headlight type. Models with halogen headlights use an H11 bulb for the low beam and a 9005 bulb for the high beam. Models equipped with LED headlights use LED units for both the low- and high-beam functions.
The front turn signals, daytime running lights, parking lights, side markers, and rear exterior lighting are listed as LED. This includes the brake lights, center stop light, tail lights, and front and rear turn signals. The reverse lights use 921 bulbs.
For interior lighting, the dome and map lights may use either 194 or 7441 bulbs. Trunk lighting may use 168 or 917 bulbs, while the vanity light uses 6615F. The automatic-lighting listing includes 2721 or 74 options; compare the replacement with the original bulb before ordering. No fog-light bulb fitment is listed for this model year.
