This 2004 Chevrolet Blazer bulb size page helps you verify the correct bulb by lighting position, so you can match the right part before you buy. Whether you are replacing a headlight, brake light, dome light, or a small interior lamp, checking the location-specific bulb listing is the easiest way to avoid a mismatch.
Use this guide as a quick reference for common exterior and interior bulbs on the 2004 Chevrolet Blazer. The chart includes sizes for key locations such as the high beam headlight, front and rear turn signals, tail and brake lights, license plate lights, map lights, and cargo area lighting.
Fitment can vary by trim, lighting package, market, and body style, so it is smart to confirm the bulb already installed in your Blazer before ordering. Some positions may use halogen bulbs from the factory, while others can be upgraded to LED if the bulb type and housing allow it. If you are considering an aftermarket conversion, make sure the bulb base, polarity, and heat output are compatible with the vehicle and the lamp assembly. For the most reliable result, compare the old bulb to the replacement and check the socket shape, connector style, and any markings on the original bulb before purchase.
The listed high beam headlight bulb is 9005. This page is organized by lighting position, so you can confirm the correct bulb for the high beam before replacing it.
The brake light bulb is listed as 3057R. If you are replacing the rear brake lamps, match that bulb size to the correct socket on the vehicle.
The tail light bulb is 3057R. On this Blazer, the tail light and brake light listings are separate, so it is worth checking both positions before ordering.
The rear turn signal bulb is 3057. This differs from the brake and tail light bulb listing, so be sure to verify the rear lamp position specifically.
Both the front turn signal light and the front parking light are listed as 3157. That makes it easier to replace either front lamp with the same bulb type when applicable.
The back up reverse light bulb is 3156. This is the bulb to check if the reverse lamps are dim or burned out.
The front side marker light bulb is 194NA. This is a specific amber-style fitment for the front marker position.
The front fog light bulb is listed as 881 for LS, and there is also an 880 option shown for Xtreme. Because trim and package differences can affect fitment, confirm which fog lamp setup your Blazer has before buying.
The license plate light bulb is listed as 194 or 7441. Either size may appear in the chart for this position, so check the installed bulb and socket style for the best match.
The dome light is listed with two original-style options: 562 and 564. Since interior lighting can vary, verify the bulb currently in your dome lamp before replacing it.
The map light has multiple listed options, including 194 or 7441, and also 212-2. The correct choice depends on the specific overhead console or lamp configuration in your Blazer.
The instrument panel light listings include 161, 37, PC74, and PC168 depending on the exact location. Because several dash illumination points can use different bulbs, match the bulb to the specific panel position.
Yes, some owners replace interior bulbs with LED equivalents, but the fit depends on the socket and the lamp housing. Check the bulb base and the installed bulb first, and make sure the LED will work correctly in that location.
Different lamps on the 2004 Chevrolet Blazer use different bulb sizes, even when they are close together on the vehicle. Organizing the page by position helps you verify the exact bulb for each light without guessing.
Yes. Checking the installed bulb is the safest way to confirm fitment, especially on a vehicle like the 2004 Chevrolet Blazer where trim, package, and body-style differences can change certain bulb applications.
