Used Ford Mustang Rear Light

The sixth-generation Mustang (S550) ran from 2015 to 2023 in the UK, with a facelift in 2018 that brought a restyled rear light cluster; rear lights from a pre-facelift 2015–2017 car and a post-facelift 2018–2023 car are not directly interchangeable. Within each of those two phases, rear lights should swap freely, but confirm with the breaker against your registration before buying.

Your 2017 sits in the pre-facelift S550 generation (2015–2017) and your 2019 sits in the facelifted S550 generation (2018–2023), and the rear light design changed at that 2018 facelift boundary. Parts from either side of that boundary are unlikely to interchange, so check with the breaker quoting against both registrations before purchasing.

Trim level — whether that's EcoBoost, GT, Mach 1, Bullitt or Shelby GT500 — does not affect rear light fitment on the Mustang; the deciding factors are generation and facelift phase, not what's under the bonnet. Bear in mind that some higher trims may have had sequential indicators or smoked lens finishes that differ cosmetically from a standard unit, so check the appearance matches what you need.

Yes, the fastback coupe and convertible have different rear body structures and the rear light clusters differ between the two body styles. Always tell the breaker which body style your car is before agreeing a price, as a light from the wrong style will not fit correctly.

The physical mounting points on the S550 platform are shared between US and UK cars, but lens colour and indicator configuration can differ due to US regulations, and whether the connector plugs straight in is something you'd need to verify. Confirm with the breaker that the unit matches your specific registration and facelift phase before committing, as electrical compatibility is not guaranteed.

You can replace a single NS (nearside, kerb side) or OS (offside, driver's side) rear light without needing to change both, as long as the replacement matches your car's facelift phase and body style. If the replacement comes from a different production period within the same facelift phase, there can occasionally be subtle shade differences in the lens, so inspect photos from the breaker if appearance is important to you.
