Need to replace a busted or broken tail light on your modern GMC Sierra?

This is the exact part you're looking for.
It's a brand new, driver's left side tail light assembly from OEMASSIVE, designed for the 2019-2024 GMC Sierra 1500 and 2500 models.
This specific light is for trucks with halogen bulbs (without the signature lighting).

It features a chrome housing with a red clear lens, giving it that sharp, factory look.

It's a direct, SAE and DOT compliant replacement, so you know it meets safety standards and will fit right in.

The bulb type for the tail light is 921 (bulbs not included).

It comes with a great return policy—60 days free return shipping on defective items, which shows they stand behind their product.
Just a heads-up, it includes the California Prop 65 warning common for automotive parts.
If your passenger side is fine and you just need the driver side, this is the one.
Get your Sierra looking whole and safe on the road again.
