Chevrolet Silverado 1500 1999 Bulb Size
Bulb size chart
This page helps you verify bulb sizes for the 1999 Chevrolet Silverado 1500 by lighting position, so you can match the correct replacement to each lamp on the truck. Whether you are replacing a headlight, brake light, interior bulb, or an under-hood lamp, checking the exact location first is the easiest way to avoid ordering the wrong part.
On this year Silverado 1500, several bulb types are used across the exterior and interior lighting system. Common fitments on this page include 9006 low beam headlights, 9005 high beam headlights, 3157A front turn signals and parking lights, 3157R tail and brake lights, and 880 fog lights, along with smaller bulbs for the dome, map, license plate, glove box, instrument panel, and other courtesy locations.
Fitment can vary with trim, cab style, bed length, market, and lighting package, so it is smart to confirm the bulb already installed before buying replacements. That is especially important if your Silverado has been converted to LED, uses aftermarket housings, or has had previous repairs, because the bulb socket may still be original even when the light assembly is not. When possible, remove the old bulb and compare the number printed on the base, then choose a replacement that matches both the bulb type and the intended use. This is the best way to avoid issues with beam pattern, warning lights, or bulbs that fit physically but do not perform correctly.
