For the 2008 Chevrolet Malibu, the low-beam headlight uses an H11 bulb, while the high beam uses H9. The fog-light fitment is listed as either H11 LED or H16 LED, so compare the installed bulb and housing before ordering.
Several exterior bulbs vary by configuration. Classic LS models use a 3157 front turn signal, parking light, and daytime running light, with 3057 rear turn and 3057R brake/tail bulbs. Hybrid models use 4157NA for the front turn signal and parking light, 3457A for daytime running lights, and 3157 rear turn and 3157R brake/tail bulbs. Some rear lighting is listed as LED.
The reverse light uses 921, and the rear side marker uses 194NA. Interior fitments include 194 or 7441 for the glove box, 168 or 917 for map lights, and 211-2 for the trunk. Hybrid dome lights require comparing the original bulb because either 562 or 561 may apply.
