Chevrolet Colorado bulb sizes and LED options

The original-equipment charts cover the 2023, 2024, 2025 and 2026 Chevrolet Colorado. Start with the light you want to replace and the original equipment on your truck. The uplevel rear lamp, for example, combines an LED tail light with separately replaceable turn, stop and reverse bulbs.

The original GM lighting charts cover 2023–2026. A separate 2015–2022 original-halogen headlight chapter uses Diode Dynamics manufacturer applications.

H11 low-beam LED options for factory halogen headlights

Diode Dynamics lists these H11 SL2 and SL2 Pro white LED pairs for the Colorado’s replaceable factory halogen low beam, including 2023–2026 models. They do not replace an original HID bulb or an integrated factory LED headlamp. The H11 application comes from Diode Dynamics; GM’s service chart below does not print a bulb number.

Select the white pair: SL2 Cool White (6000K) — DD0467P or SL2 Pro White — DD0483P. Each offer contains two bulbs.

For this low-beam application, Diode Dynamics reports full-brightness operation when used as the daytime running light.

LED headlight conversion bulbs may not comply with FMVSS/CMVSS requirements for on-road use. Check applicable state and provincial laws before use.

9005 high-beam LED options for factory halogen headlights

For the separate replaceable halogen high beam, Diode Dynamics lists these 9005 SL2 and SL2 Pro white pairs. Select them for that original high-beam configuration, independently of the truck’s low beam or rear lights.

Select the white pair: SL2 Cool White (6000K) — DD0463P or SL2 Pro White — DD0481P. Each offer contains two bulbs.

Manufacturer use and installation information

Diode Dynamics states that these conversion bulbs are not DOT compliant for use in headlamps on public roads in the United States. GM also cautions that replacing incandescent bulbs with aftermarket LEDs can damage the vehicle electrical system. Follow the selected product’s installation instructions and stated intended use.

GM directs owners to a dealer for replacement bulb types and service of LED lighting assemblies. The product names above identify Diode Dynamics’ application choices; they do not turn an integrated LED assembly into a replaceable-bulb housing.

2023–2026 Colorado original lighting chart

These positions appear in each of the four model-year owner’s manuals. GM uses Base and Uplevel for the lamp configurations; the front and rear configurations are independent. The manuals describe bulb replacement but do not supply trade numbers for these removable bulbs.

The two Base rear combined functions are separate entries. The Uplevel rear LED tail light does not make its turn, stop or reverse bulbs LED. Cargo lights and the center brake light also have separate replacement instructions.

Rear turn/tail and reverse bulb references

Rear turn/tail: Diode Dynamics lists red 7443 LED replacements for the original replaceable incandescent bulbs behind red lenses. Its HP48, HP11 and XP80 packages each contain four bulbs; HP48 is described as a cosmetic upgrade. The manufacturer requires one 6-ohm resistor for every replaced turn-signal bulb; resistors are separate. This application uses BCM control rather than a removable flasher.

2023–2026 Colorado reverse-light LED pairs

Reverse: Diode Dynamics identifies a 921 reverse application and lists its Cool White HP5, HP36 and XPR pairs. It advises that most customers do not need a reverse resistor; a bulb-out warning or irregular operation may require one. That differs from the mandatory turn-signal resistor instruction above.

Choose these pairs only for the original removable 921 reverse bulb. An integrated LED reverse lamp needs its own matching service part. Each listing contains two bulbs; check the installed quantity. The HP5 product is labelled 194 and is specifically listed by Diode for this 921 application; this is not a universal 194/921 interchange rule.

Supplier order lead time: 1–2 days when in stock at Diode Dynamics.

Match the original replaceable bulb and output color, and check the number of bulbs you intend to replace when ordering.

2026 Colorado headlight, fog and cargo-light equipment

Chevrolet’s comparison lists halogen headlights and halogen daytime running lamps for WT 2WD and Trail Boss 4WD. For the separately shown Z71 4WD, it lists LED projector headlights/DRL, LED fog lamps and LED tail lamps. The LED tail specification does not describe every function inside that rear housing.

2022 Colorado factory bulb service

The 2022 owner’s manual identifies a shared low-beam/daytime-running-light position and a separate high beam. It directs passenger-side headlight, front turn, parking and side-marker bulb replacement to a dealer. Ask your dealer for the correct replacement bulb type: the manual does not list bulb numbers.

The cab-mounted cargo lamps and center high-mounted brake light are separate functions with their own bulb positions. Identify the lamp you are replacing before ordering.

Chevrolet cautions against replacing incandescent bulbs with aftermarket LEDs because this can damage the vehicle’s electrical system. Check the original equipment and the selected product’s installation instructions before choosing a replacement.

2021 Colorado factory bulb service

For a 2021 Colorado, the owner’s manual directs you to the dealer for the correct replacement bulb type. Its service instructions identify the low-beam headlamp/DRL and high beam separately and direct passenger-side replacement to the dealer. These instructions do not supply a bulb-size chart.

2021 lamp service and original source

The manual describes cargo-light operation, including pickup-box lamps if equipped, but does not give a cargo or high-mounted stoplamp replacement procedure in its bulb-service section. Identify those lamps separately.

Follow the manual’s halogen handling and socket-removal instructions. GM cautions against replacing incandescent bulbs with aftermarket LEDs because they can damage the electrical system. Check the installed lamp and the selected product’s application before changing it.

2020 Colorado factory bulb service

The 2020 manual identifies the low-beam headlamp/DRL and high beam separately, with a combined front turn/parking position and a separate sidemarker. Passenger-side replacement is directed to the dealer. Ask the dealer for the correct bulb type; these service instructions do not supply bulb numbers.

2020 lamp service and original source

The manual supplies a cargo and center high-mounted stoplamp replacement procedure, with the cargo and brake bulbs labeled separately. Pickup-box lamps, where equipped, need their own identification. The rear diagram distinguishes combined stop/tail/turn, reverse, and combined stop/tail/turn/sidemarker positions.

Follow the halogen handling and socket-removal instructions. GM cautions against replacing incandescent bulbs with aftermarket LEDs because they can damage the electrical system.

2015–2022 Colorado headlight applications — original halogen equipment

Diode Dynamics lists the following applications for 2015–2022 Chevrolet Colorado trucks with the original removable halogen bulbs. Factory HID and integrated LED headlights are excluded. These manufacturer applications are separate from the 2023–2026 GM lighting charts and reverse-light options above.

Select White for these headlight applications. Each listing contains two bulbs; check the quantity needed at the chosen position. This chapter does not assign older fog, signal or rear-light bulbs.

LED headlight conversion bulbs may not comply with FMVSS/CMVSS requirements for on-road use. Check applicable state and provincial laws before use.

Supplier order lead time: 1–2 days when in stock at Diode Dynamics.

Manufacturer sources and the 2022 Z71 dust-cap answer

In its answer about a 2022 Colorado Z71, Diode Dynamics says SL2 and SL2 Pro can operate enclosed behind a dust cap. That answer applies to the named configuration; it is not a separate clearance test for every 2015–2022 housing.

Diode Dynamics low-beam application and high-beam application. Match the original bulb and follow the selected product’s installation and intended-use instructions.

2015–2020 Colorado GTR Ultra 3.0 headlight options

For 2015–2020 Colorado trucks with the original replaceable halogen headlight bulbs, these GTR Ultra 3.0 pairs provide a separate manufacturer-listed option. Use H11 for the low beam and 9005 for the high beam. This GTR application does not extend to 2021–2022 or newer models, factory HID or integrated LED headlights.

H11 low-beam pair — GTR.LED801 · 9005 high-beam pair — GTR.LED803. Each product contains two bulbs and an Allen key. Check the installed quantity for the position you are replacing; one pair is not a complete low-and-high-beam set.

LED headlight conversion bulbs may not comply with FMVSS/CMVSS requirements for on-road use. Check applicable state and provincial laws before use.

GTR application sources and package details

The supplier’s 2015–2020 Colorado low-beam application and 2015–2020 Colorado high-beam application identify the matching Ultra 3.0 bulb pairs. The cards link to those standard bulb-pair products at BTS. Optional grease is separate. Follow GTR’s installation and use instructions for the selected product and original housing.
