For the 2010 Acura TSX, the low-beam headlight uses a D2S bulb, while the high beam uses a 9005. The daytime running light is also listed as 9005. For fog lights, the supplied fitment data lists both H11 LED and H16 LED options, so verify the existing fog-light socket and housing before ordering.
Other notable exterior bulbs include 7528 for the front turn signal, parking light, and front side marker; 7440A for the rear turn signal; 7443R for the brake and tail lights; and 7440 for the reverse and center stop lights. Rear side markers use 168NA.
Interior and auxiliary fitments include DE3175 for the dome and map lights, 6615F for the vanity light, and 194 or 7441 for the interior application listed. License plate and trunk lights are listed as either 168 or 917. Because the data includes multiple options for some locations, compare the removed bulb and socket style before replacement.
