For the 2006 Chevrolet Cobalt, both the low-beam and high-beam headlights use a 9007 bulb. The same 9007 fitment serves both headlight functions, so verify the existing bulb and housing before ordering replacements.
Fog-light fitment is listed with two options: H11 LED and H16 LED. Confirm which option matches your fog-light assembly. Other useful exterior bulb sizes include 3457A for the front turn signals and parking lights, 3157R for the brake and tail lights, and 3157 for the rear turn signals.
- Reverse lights: 921
- Center stop light: 912
- Front and rear side markers: 194NA
- License plate lighting: 194 or 7441
Interior listings include 212-2 for the courtesy light, 562 for the dome light, 2825 or 98 for map lights, and 168 or 917 for the trunk light. Because multiple options are listed for some locations, compare the original bulb and socket before purchase.
