Chevrolet Corvette 2003 Bulb Size
Bulb size chart
This 2003 Chevrolet Corvette bulb guide is organized by lighting position so you can quickly verify the correct bulb size before you buy. Whether you are replacing an exterior signal lamp, a cabin light, or a small utility bulb, this page helps narrow the fitment by location and reduces the chance of ordering the wrong part.
The 2003 Chevrolet Corvette uses a mix of common halogen and miniature bulbs, and several positions may vary depending on trim, market, or lighting package. Use the bulb chart to match each socket to the listed size, then confirm the installed bulb if you are replacing a light that has been changed before.
For the best fit, compare your Corvette’s installed bulb to the chart before purchasing, especially if the car has been modified or fitted with aftermarket lighting. Some owners switch from halogen to LED for brighter output or lower power draw, but LED conversions can change beam pattern, polarity, or bulb depth, so make sure the replacement is compatible with the housing. Trim and package differences can affect courtesy, map, and indicator lights, and the same position may use a different bulb in another market or body style. When in doubt, remove the old bulb and match the base, shape, and connector before ordering.
