Bulb size chart
If you are replacing exterior or interior bulbs on a 2002 Chevrolet Suburban 1500, this page helps you verify the correct bulb size by lighting position. The Suburban uses different bulbs for the headlamps, turn signals, brake lights, dome lights, and smaller courtesy or panel lamps, so matching the bulb to the exact location is the safest way to buy the right part.
Because trim and lighting package can vary by market and body style, it is smart to compare the bulb chart with the lamp on your vehicle before ordering. Common fitments on this model include 9006 low beams, 9005 high beams, 3157R brake and tail bulbs, 3157A rear turn signals, and several interior bulbs such as 578, 194, 161, and DE3175.
For the best fitment results, check whether your 2002 Chevrolet Suburban 1500 uses standard halogen bulbs or has been modified with LED replacements, since aftermarket conversions can change the bulb type, socket fit, or warning behavior. Some trims and packages may also use different lamp assemblies, so it is a good idea to confirm the installed bulb number before purchase, especially for items like fog lights, daytime running lights, and instrument panel bulbs. If you are upgrading to LED, make sure the replacement is compatible with the housing and beam pattern, and verify that the bulb base matches the original socket exactly.
