2022 Chevrolet Silverado 1500 Bulb Sizes (Headlight, Tail, Fog)

Quick reference

The 2022 Chevrolet Silverado 1500 offers a variety of lighting options, making it important to know which bulbs are in your specific truck. Chevrolet utilized both traditional halogen bulbs and integrated LED lighting across different trim levels and packages for the refreshed 2022 model year. Understanding these differences is key when considering replacements or upgrades.

For the headlights, many lower and mid-range trims came standard with halogen reflector headlights, utilizing H11 bulbs for low beams and 9005 bulbs for high beams. However, higher trim levels and optional lighting packages featured advanced LED projector headlights. These LED headlights typically use integrated, non-replaceable LED arrays for both low and high beam functions, meaning individual bulb replacement is not possible; the entire headlight assembly would need to be replaced if the LEDs fail. Fog lights follow a similar pattern, with H11 halogens being common on many trims, while higher trims might include integrated LED fog lights.

Daytime Running Lights (DRLs) on most 2022 Silverado 1500 models are integrated LED strips, often part of the main headlight assembly, offering a distinct light signature. Front turn signals can vary, with some trucks using 7443 incandescent bulbs and others featuring integrated LED turn signals within the headlight assembly. Rear turn signals, brake lights, and tail lights often share similar bulb types, with 7440 for turn signals/tail lights and 7443 for brake lights being common incandescent sizes on models without full LED taillight assemblies. Many higher trims, or optional packages, came with full LED taillight assemblies where these functions are integrated and not individually serviceable. Reverse lights are commonly 921 incandescent bulbs on models with traditional taillight assemblies, though LED taillights will have integrated LEDs for the reverse function.

For smaller exterior lights, license plate lights typically use 194 incandescent bulbs, though some trims might have LED equivalents. Front side marker lights are usually 194 incandescents, often integrated into the headlight housing. Rear side markers can be integrated LEDs within the taillight assembly on models with full LED taillights. Inside the cabin, dome and map lights are generally LED, using sizes like 578 for the dome and 194 for map lights on most trim levels.

LED vs halogen upgrade considerations

Upgrading from halogen to LED bulbs in your 2022 Chevrolet Silverado 1500 can significantly improve light output, lifespan, and aesthetics. However, it's not always a straightforward plug-and-play process, especially with modern vehicle electronics. The Silverado's electrical system uses a Controller Area Network (CANBUS) to monitor various components, including lighting. When you replace a halogen bulb with an LED, the lower power draw of the LED can trick the CANBUS system into thinking there's a bulb out, leading to "bulb-out" warning messages on your dash or hyperflashing (rapid blinking) of your turn signals. To prevent these issues, you'll often need to use CANBUS-compatible LED bulbs or install external load resistors (decoders/adapters) for each LED bulb. These resistors mimic the electrical load of a halogen bulb, satisfying the CANBUS system. Ensure any aftermarket LEDs are designed for automotive use and compatible with your Silverado's electrical system.

Another consideration is fitment. While many LED bulbs are designed to be compact, some high-performance LED conversions feature larger heatsinks or external drivers that might require more space behind the headlight assembly or within the taillight housing. Always verify clearances before purchasing and installing. For exterior lights like headlights and fog lights, consider LED bulbs with proper beam patterns to avoid blinding oncoming traffic; some aftermarket LEDs can scatter light excessively in halogen reflector housings.

How to replace each bulb

• Low Beam Headlight (H11) / High Beam Headlight (9005): Access is usually from behind the headlight assembly in the engine bay. Twist the bulb counter-clockwise to remove. Disconnect the electrical connector, then install the new bulb by reversing the process. For LED headlights, replacement is not a simple bulb swap; the entire assembly typically needs replacement.
• Fog Light (H11): Often accessed from underneath the front bumper or by removing the inner fender liner. Twist the old bulb out, disconnect, and install the new one.
• Front Turn Signal (7443): Usually accessed from behind the headlight assembly. Twist the socket to remove, pull out the old bulb, and press in the new one.
• Rear Turn Signal (7440), Brake Light (7443), Tail Light (7440): Access typically involves removing the taillight assembly from the truck. This usually requires removing a couple of mounting screws, then carefully pulling the assembly straight back. Once the assembly is out, twist the bulb sockets to remove them, replace the bulbs, and reassemble.
• Reverse Light (921): Similar to rear turn signals, accessed by removing the taillight assembly.
• License Plate (194): Usually accessed by carefully prying down the clear lens cover with a plastic trim tool, or by unscrewing a small housing. Unplug the old bulb and plug in the new one.
• Front Side Marker (194): Often integrated into the headlight assembly; replacement might involve accessing from behind the headlight.
• Rear Side Marker: On models with integrated LED taillights, these are not individually replaceable. On other models, these might be part of the main taillight assembly or a small, separate integrated LED.
• Dome Light (578): Carefully pry off the clear lens cover with a plastic trim tool. The bulb is typically a festoon type that clips into place. Gently unclip and replace.
• Map Light (194): Similar to the dome light, carefully pry off the lens cover. The 194 bulb usually pulls straight out of its socket.

Always consult your owner's manual for specific instructions and warnings regarding bulb replacement.

Common lighting issues for this generation

The 2022 Chevrolet Silverado 1500, particularly as it marks a refresh year, can present some specific lighting considerations. One common "issue" isn't a defect but rather a characteristic of modern vehicles: the complexity of LED lighting systems. If an integrated LED unit (e.g., in a DRL strip, headlight, or full LED taillight) fails, it often requires replacing the entire assembly, which can be significantly more expensive than just replacing an incandescent bulb. Owners should be aware of this potential cost.

Another common topic is the difference in light output and beam patterns between factory halogen and factory LED headlights. Some owners upgrading from older halogens may find the "new" halogens on base models underwhelming compared to the brighter, whiter light of the optional LED headlights or aftermarket LED conversions. This can lead to questions about upgrades and compatibility. As mentioned, CANBUS errors and hyperflashing are typical concerns when installing aftermarket LEDs without proper decoders or resistors.

Weather-related issues, such as condensation inside headlight or taillight housings, can occasionally occur. While a small amount of condensation that dissipates quickly is often considered normal by manufacturers, excessive moisture buildup can indicate a seal issue and may require inspection. Ensure any aftermarket seals or caps are properly installed after bulb changes to prevent moisture ingress.
