2022 Chevrolet Tahoe Bulb Sizes Guide

Quick reference

The 2022 Chevrolet Tahoe represents a modern approach to vehicle lighting, with a significant shift towards integrated LED technology for many exterior functions, particularly on higher trim levels. This guide will help you navigate the various bulb sizes and types found in your Tahoe, from the powerful headlights to the subtle interior lighting.

For the 2022 model year, many Tahoe trims (especially Premier and High Country) come standard with full LED exterior lighting for the headlights, DRLs, and many tail light functions. Lower trims like LS, LT, and RST may still utilize some traditional halogen bulbs, particularly in certain rear lighting applications and fog lights.

Headlight Bulbs

The 2022 Chevrolet Tahoe, across most of its trim levels, features advanced LED projector headlights. This means the low beam and high beam functions are handled by integrated LED units, not replaceable individual bulbs. These LED headlamps provide superior illumination, a longer lifespan, and a distinct modern appearance compared to traditional halogen systems. If you encounter an issue with an integrated LED headlight, the entire assembly typically needs to be replaced, which is a more complex and costly repair than a simple bulb swap.

Fog Lights

Fog lights on some 2022 Tahoe trims, especially the LS, LT, and RST, may still use a PSX24W halogen bulb. Higher trims like Premier and High Country often come with integrated LED fog lights, matching the main headlamp units. If your Tahoe has halogen fog lights and you're considering an upgrade, ensure any aftermarket LED replacements are compatible with the PSX24W socket and have proper heat dissipation.

Daytime Running Lights (DRL)

All 2022 Chevrolet Tahoe models come with integrated LED Daytime Running Lights. These are part of the headlight or front fascia assembly and are not designed for individual bulb replacement.

Front Turn Signals

Similar to the DRLs and headlights, the front turn signals on the 2022 Tahoe are integrated LED units across all trims. These provide crisp, instant illumination for increased visibility.

Rear Turn Signals

Here's where trim level differences become more apparent. On LS, LT, and RST trims, the rear turn signals typically utilize a 7440 halogen bulb. For Premier and High Country trims, the rear turn signals are integrated LED units, often part of a more sophisticated full-LED tail light assembly.

Brake Lights & Tail Lights

Many 2022 Tahoe trims feature integrated LED brake and tail lights. This is especially true for the Premier and High Country, where the entire tail light assembly is LED. Lower trims (LS, LT, RST) may have some integrated LED components for the tail lights, but often utilize the 7440 bulb for combined brake/tail light functions where LEDs are not integrated or a separate halogen brake bulb might be used, though integrated LEDs are increasingly common even on lower trims for brake lights due to safety standards.

Reverse Lights

Mirroring the rear turn signals, reverse lights on LS, LT, and RST trims typically use a 7440 halogen bulb. Premier and High Country models will commonly have integrated LED reverse lights.

License Plate Lights

The license plate lights on the 2022 Tahoe commonly use a 194 or T10 halogen bulb. These are straightforward to replace and are a popular candidate for aftermarket LED upgrades due to their accessibility and the aesthetic improvement an LED provides.

Side Marker Lights

Both front and rear side marker lights on the 2022 Tahoe are generally integrated LED units, designed for long-term use without bulb replacement.

Interior Dome and Map Lights

Interior lighting can vary significantly by trim. On lower trims (LS, LT, RST), you might find traditional halogen festoon bulbs (e.g., 28mm for dome lights) and 194/T10 wedge bulbs for map lights. Higher trims (Premier, High Country) commonly feature integrated LED interior lighting throughout the cabin, offering brighter and more efficient illumination. It's best to visually inspect your specific Tahoe's interior lighting to confirm the bulb type before purchasing replacements or upgrades.

LED vs Halogen Upgrade Considerations

If your 2022 Chevrolet Tahoe has halogen bulbs in any location (such as fog lights, rear turn signals, reverse lights, or interior lights) and you're considering upgrading to LEDs, there are a few important factors:

• CANBUS Errors: Modern vehicles like the Tahoe utilize a CANBUS system to monitor electrical circuits. Halogen bulbs draw more power than LEDs. If you replace a halogen bulb with an LED without an appropriate CANBUS-compatible LED bulb or load resistor, the vehicle's computer may detect a difference in resistance, interpret it as a
