This page helps you verify bulb sizes for the 2009 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, a license plate light, or a cabin bulb, checking the exact location is the easiest way to avoid ordering the wrong part.
The 2009 Chevrolet Cobalt uses different bulb types across the exterior and interior, and some fitments can vary by trim, body style, or lighting package. Use the bulb chart on this page as a quick reference for common positions like low and high beams, tail lamps, turn signals, map lights, and reverse lights.
Fitment can change depending on trim, package, and market, so it is smart to compare the bulb listed for your position with the one already installed in your car. That is especially important if you are switching from halogen to LED, since aftermarket LED replacements may fit the socket but still need the correct base, polarity, and beam pattern. Some lighting conversions can also affect warning messages, brightness, or legality on public roads. Before you place an order, remove the old bulb and check the stamped number on the base whenever possible, then confirm it matches the bulb chart for your 2009 Chevrolet Cobalt.
