2019 Chevrolet Equinox — Bulb Sizes (Headlight, Tail, Fog)

Quick reference

Notes: Mid‑year/trim changes occur. Always verify by VIN or inspecting the socket before ordering. LED headlamp/tail assemblies are typically non‑serviceable at the bulb level.

LED vs halogen upgrade considerations

• Headlights: Replacing H11/9005 halogens with LED retrofit bulbs can improve color and output, but many retrofit LEDs may scatter in the Equinox’s reflector housings. Choose reflector‑optimized LED kits, and aim/verify beam pattern after install.
• CANBUS/hyperflash: Front/rear turn signals switched to LED may trigger hyperflash or bulb‑out messages. Use CANBUS‑ready LEDs or add load resistors (approx. 6Ω/50W per turn circuit) mounted to metal away from plastics.
• DRL behavior: On halogen trims the 9005 high beam runs at reduced voltage for DRL. Some LED retrofits will flicker or not illuminate as DRL due to PWM. Look for DRL‑compatible LEDs or a dedicated DRL/anti‑flicker module.
• Fog lights: H11/H16 LED upgrades generally work without errors, but verify housing clearance and heat management.
• Interior/license/trunk: These usually accept plug‑and‑play LEDs without error. White 6000K is popular; warm 4000K is easier on eyes inside the cabin.
• LED‑equipped trims: If your Equinox has factory LED headlamps or LED tails (common on some Premier packages), individual bulbs are not replaceable; the full assembly is serviced as a unit.

How to replace each bulb

• Low beam (H11): Turn the wheel inward, remove the fender‑liner access panel, rotate the H11 bulb counterclockwise, swap bulb, avoid touching glass, and reseat the dust cap if present.
• High beam/DRL (9005): Access from behind the headlamp similar to low beam; twist out and replace. Confirm DRL operation after install.
• Fog light (H11/H16): From below or through the lower splash shield, twist the bulb out of the housing. Check the O‑ring and reseal.
• Front turn (7440A): Access from the rear of the headlamp; rotate the socket 1/4 turn, pull out, swap the wedge bulb. Test for hyperflash if using LED.
• Rear tail/brake/turn (7443): Open liftgate, remove lamp fasteners, pull the assembly straight back to release pins, twist the socket, and replace the 7443. Ensure the dual‑filament orientation is correct.
• Reverse (921): With the tail lamp off the vehicle, twist the reverse socket and replace the 921.
• Rear side marker (194): Shares the tail assembly; remove and replace like the others.
• License plate (194): Remove the small lens screws at the liftgate garnish, pop the socket, and replace the 194.
• Interior map (194): Pry the lens carefully with a trim tool, pull the wedge bulb straight out, install LED observing polarity.
• Dome/cargo (31mm): Gently pry the lens, release the festoon from spring clips. If upgrading to LED, verify festoon length and polarity.

Torque lamp fasteners snugly, not excessively. Always test all functions (low/high, DRL, turns, brakes, hazards, reverse, plate) before reassembling panels.

Common lighting issues for this generation

• Hyperflash after LED turn signal swap: Add resistors or use CANBUS‑built LEDs.
• DRL flicker with LED high‑beam retrofits: Choose DRL‑compatible bulbs or add an anti‑flicker module.
• Moisture in headlamp/tail lamp: Check vent caps and seals; replace compromised gaskets. Persistent moisture may require assembly replacement.
• Dim or scattered headlight output: Aim headlights per spec and use quality bulbs; avoid over‑wattage halogens that can overheat sockets.
• Melted 7443 sockets: Caused by cheap high‑watt bulbs; replace socket pigtails if heat‑damaged.
• Inoperative license/map lights: Commonly a blown 7.5A INT LAMP fuse or polarity issue after LED install.
