Our guide covers 6 model years for the GMC Terrain (2016–2025) but only 3 for the Kia Optima (2018–2020), so the GMC Terrain data reflects a broader range of generations.
Only 69% of Kia Optima tail light listings include a posted price (1,773 of 2,561 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
The GMC Terrain tail light is interchangeable across 17 model years versus just 5 for the Kia Optima — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
Buyer's checklist
What to check before buying a used tail light
- Look for cracks in the lens — even hairline cracks let in moisture and will eventually fog the housing.
- Confirm the assembly matches your trim level. Base and higher trims often use different tail light designs.
- Check that the wiring harness connector and all bulb sockets are intact.
- Verify inner vs outer — many vehicles use separate inner (trunk lid) and outer (quarter panel) tail lights.
