For the 2016 Honda Civic, headlight bulb fitment depends on the factory headlight type. Models with halogen headlights use an H11 bulb for the low beam and 9005 for the high beam. Models equipped with LED headlights use integrated LED lighting for both the low- and high-beam functions.
Other lighting varies by body style and equipment. The front turn signal uses 7440A with halogen headlights, while LED-headlight models use LED lighting. Reverse lights use a 921 bulb. Brake-light fitment differs between body styles: coupes use 7506R, while sedans use 7440R. Rear turn signals use 7507 on coupes and 7440A on sedans.
Additional supplied fitments include a 2821 front side marker and LED tail, rear side-marker, daytime-running, parking, and license-plate lights. Dome and map lights may use 194 or 7441, while the trunk light may use 168 or 917. Verify the vehicle’s headlight type and body style before ordering.
