What headlight bulb for 2014 Chevy Impala?

For most 2014 Impalas with halogen headlights, the low beams use H11 bulbs and the high beams use 9005 bulbs. If your car has the optional HID headlights, the bulbs are xenon types (D1S or D2S) used with a ballast. Confirm by checking your owner's manual, VIN-specific parts diagram, or inspecting the ballast and bulb configuration in the headlight assembly.

The 2014 Chevrolet Impala offered two main headlight configurations: standard halogen projector headlights and an optional HID (xenon) setup. The exact bulb needed depends on which system your vehicle uses, as well as whether you’re replacing a low beam, high beam, or fog light. This article covers common configurations, how to identify your setup, and how to replace the bulbs correctly.

Halogen headlight setup (standard on many trims)

The following applies to Impala models that arrive with traditional halogen projector headlights rather than HID. Use these as the go-to replacements if your car doesn’t have the xenon option.

• Low beam bulb: H11


• High beam bulb: 9005 (HB3)


• Fog light bulb (if equipped): H11

These are the most common replacements for the halogen configuration on a 2014 Impala. Always verify with the owner’s manual or a parts diagram if you’re unsure about your trim’s exact setup.

HID headlight setup (optional on some trims)

On models equipped with HID headlights, the low-beam (and sometimes the high-beam) lighting is driven by xenon bulbs paired with a ballast. The exact bulb type commonly used in GM HID systems is D1S or D2S, depending on the ballast configuration. Some configurations may still use a halogen high beam in conjunction with the HID low beam.

• Low beam bulb: D1S or D2S (depends on ballast)


• High beam: often a separate halogen bulb (commonly 9005) in many HID-low-beam configurations; check your vehicle’s setup


• Fog lights (if present and HID-equipped): typically not part of the HID assembly; verify if your model uses halogen fogs

To confirm the exact bulb type for your car, look for the ballast housing near the headlamp, check the bulb label, or consult the VIN-specific Chevrolet parts lookup. If in doubt, a dealership or qualified mechanic can confirm the correct bulb type for your exact trim and production date.

How to verify bulb type on your own

Open the hood and inspect the headlight assembly with the electrical connector unplugged. The bulb base and any markings on the bulb itself will indicate the correct type (for example H11, 9005, D1S, or D2S). If the headlight housing has a ballast, it’s a strong sign you’re dealing with HID rather than pure halogen. When handling new bulbs, wear gloves to avoid contaminating the glass.

Replacement steps by bulb type

The following guidance helps you replace the most common bulbs found in 2014 Impalas. Always disconnect the battery before starting work and handle bulbs with care to avoid oils on the glass.

• Halogen (H11 low beam): remove the dust cap, release the retainer, pull out the old bulb, insert the new H11, reconnect, and test


• Halogen high beam (9005): access from the engine bay, detach the high-beam socket, replace with new 9005, reseat, and test


• HID bulbs (D1S/D2S): due to ballast integration, replacement is often best handled by a professional; if you do it yourself, disconnect the ballast, carefully handle the HID bulb by its base, install with the ballast reconnected, and test

Note: If your Impala uses HID headlights, incorrect handling can damage the ballast or electrical system. When in doubt, seek professional service to ensure proper alignment and electrical safety.

Summary

The 2014 Chevrolet Impala can use either halogen or HID headlight setups. Halogen configurations typically require H11 low beams and 9005 high beams (with H11 also common for fog lights). HID-equipped models use xenon bulbs such as D1S or D2S in conjunction with a ballast, and some trims may still use a halogen high beam. To be certain, verify your trim’s original equipment via the owner's manual, VIN-based parts lookup, or a Chevrolet dealer. Accurate identification ensures you choose the correct bulbs and avoid mismatches.

Tips for shoppers and installation

When buying bulbs, bring the exact bulb type label or use your vehicle’s VIN to pull the correct specification from Chevrolet’s parts catalogs. If you’re replacing HID bulbs, plan for possible ballast considerations and consider professional replacement to avoid damage.
