Chevrolet Cobalt 2005 Bulb Size
Bulb size chart
This page helps you find the correct bulb sizes for the 2005 Chevrolet Cobalt by lighting position, so you can match the right bulb to the right socket before you buy. Whether you are replacing a headlight, tail light, license plate light, or interior bulb, checking the fit by location is the easiest way to avoid ordering the wrong part.
The 2005 Chevrolet Cobalt uses several different bulb types depending on where the light is installed, and some positions may vary by trim, body style, or market. Use the bulb chart on this page to verify each location individually, especially if you are replacing more than one bulb at the same time.
For best fitment, compare the bulb listed for your lighting position with the bulb already installed in your vehicle, since trim and lighting package differences can change the exact application. This is especially important if you are switching between halogen and LED bulbs or using aftermarket conversions, because some LED replacements may need additional compatibility checks for beam pattern, polarity, or warning issues. Before purchasing, remove one bulb and confirm the base style and markings on the glass or housing whenever possible.
