Chevrolet Silverado 1500 2002 Bulb Size
Bulb size chart
This page helps you verify the bulb sizes for the 2002 Chevrolet Silverado 1500 by lighting position, so you can match the correct replacement before you buy. Whether you are replacing a headlight, tail light, interior lamp, or dash indicator, checking the exact socket location is the easiest way to avoid ordering the wrong bulb.
The 2002 Silverado 1500 uses a mix of exterior, interior, and instrument bulbs, and some fitments can change with trim, body style, or lighting package. Use the bulb chart on this page to confirm each position separately, especially if your truck has factory fog lights, daytime running lights, or different cargo and courtesy light setups.
For the best fit, compare the bulb number on the chart with the bulb currently installed in your truck before purchasing. Trim and package differences can affect certain lamps, and aftermarket LED conversions may require a different bulb type, added load resistors, or a compatible flasher to work correctly. If you are upgrading from halogen to LED, make sure the new bulb matches the socket, beam pattern, and space available behind the housing, since some replacements are physically larger than the original. When in doubt, remove one bulb, read the number on the base, and verify it against the chart before ordering a full set.
