The safest way to choose a replacement rear lamp is to match the vehicle, side, original lighting configuration, and reference number—not the product photo alone.
Quick Answer
If you are replacing the rear lamp on the passenger side of a 2015–2022 Chevrolet Colorado, confirm three things before ordering: the right/RH position, the original halogen configuration, and the OE or reference number. Merton lists OEM 84630993 for this passenger-side assembly. Compare the original lamp and vehicle details instead of choosing by appearance alone.
Is This the Correct Side?
Automotive parts are labeled from the driver’s seated position. On a U.S.-market Chevrolet Colorado:
- Passenger side: Right side or RH
- Driver side: Left side or LH
- Product position: Rear right/passenger/RH
- Lighting type: Halogen
- Merton-listed years: 2015–2022
- Merton-listed trims: LT, WT, Z71, and ZR2
Stand behind the truck and face forward: the passenger-side lamp will appear on your left. That viewpoint can cause ordering mistakes, so use the seated-driver convention. This product is one passenger-side assembly, not a pair or a driver-side lamp.
Complete Assembly or Just a Bulb?
A complete tail light assembly includes the exterior housing and lens. A bulb-only repair may be enough when the housing, lens, mounting points, sockets, seals, and wiring remain serviceable.
Consider an assembly-level replacement when the lens or housing is cracked, the mounting points are broken, the lamp does not sit securely, or moisture has entered through physical damage. If the housing is sound and only one lighting function is out, diagnose why the Colorado tail light is not working before buying an assembly.
The Merton assembly includes bulbs and a wiring harness. Compare the included connector, socket layout, and wire routing with the original assembly before installation.
Match the Original Halogen Setup
Merton identifies this product as a halogen tail light assembly. Match the replacement to the original lamp configuration. Do not assume that a lamp intended for a halogen setup will replace an LED-specific or modified setup simply because the lens shape looks similar.
Exact vehicle configuration still matters. Compare the original lamp and submit the year, make, model, trim, side, and OE number through Merton Fitment Help when you need confirmation.
OEM and Replacement Numbers
Merton lists the following references for the right/passenger-side assembly:
| Reference type | Number |
|---|---|
| OEM listed by Merton | 84630993 |
| Replaces | 23266270 |
| Replaces | 23283791 |
| Replaces | 84169778 |
| Replaces | 84916712 |
| Replaces | 94776928 |
Reference numbers are useful comparison points, but they should not be the only fitment check. A superseded or cross-referenced number can still require verification against the truck’s exact configuration.
Checklist Before You Order
- Confirm that the truck is a 2015–2022 Chevrolet Colorado.
- Confirm that the damaged lamp is rear right/passenger/RH.
- Match the original halogen lighting configuration.
- Compare the lens shape, mounting points, sockets, and connections with the original lamp.
- Compare OEM 84630993 and the listed replacement references.
- Confirm that the included bulbs, wiring harness, connector, and socket layout match the original assembly.
When any item does not match, pause before checkout and send Merton the vehicle details, OE number, and clear photos of the original lamp.
What to Check After Installation
After the assembly is seated and secured, test the lighting functions that apply to the vehicle, including the running light, stop light, turn signal, and reverse light. Check that the housing sits flush with the box side and does not move.
For the removal and installation sequence, see the separate guide on how to replace a 2015–2022 Chevy Colorado tail light assembly.
Frequently Asked Questions
Is this the right or left Chevy Colorado tail light?
It is the right/passenger-side rear lamp, also called RH. The left/driver-side or LH assembly is a different part position.
What years does Merton list for this assembly?
The Merton product page lists 2015–2022 Chevrolet Colorado applications and names LT, WT, Z71, and ZR2 trims. Buyers should still compare the original lighting configuration and vehicle information.
What OEM number is listed?
Merton lists OEM 84630993. It also lists 23266270, 23283791, 84169778, 84916712, and 94776928 as replacement references.
Does the assembly include bulbs and wire?
Yes. The Merton assembly includes bulbs and a wiring harness. Confirm that its connector and socket layout match the original assembly before installation.
Can this replace an LED tail light?
Do not assume so. Merton identifies this as a halogen assembly. Match the original lighting configuration or request a fitment check before ordering.
