| Genuine (OE) numbers quoted | None quoted in the catalogue listings — the genuine light varies by trim, bulb or LED type and facelift date, so order it against your VIN |
| Fitment notes | Left and right are separate parts; check LED or bulb type, whether the bulb holder is included, body style and facelift date before ordering. |
Ford's Own Handbook Confirms Some Condensation Is Genuinely Normal — Ford Fiesta Tail Lights
Worth knowing before assuming a fault: Ford's owner handbook explicitly states that condensation in exterior front and rear lamps is normal, since the units include vents designed to accommodate everyday humidity changes. Light misting that appears after washing, in rain, or overnight, then clears within a few hours as the light warms up or the car's been driven, is genuinely nothing to worry about. What actually indicates a real problem: a persistent pool of standing water at the bottom of the unit, moisture that doesn't clear after several hours in the sun, or condensation that gets worse over time rather than clearing — this points to genuine water ingress from a failed seal, worth having inspected rather than dismissed as normal venting behaviour.
Ford Fiesta Tail Lights: More Wiring Behind There Than Most People Assume
The Ford Fiesta's tail light unit typically bundles several functions into one housing — brake light, indicator, reversing light and rear fog light — which means a single electrical fault can affect more than one function at once, and a "faulty tail light" can mean several genuinely different things.

Ford Fiesta Tail Lights: What It Does
Beyond basic rear visibility, tail light units on the Fiesta typically integrate brake lights, indicators, reversing lights and rear fog lights into a single housing. Higher trims may use LED units with a distinct light signature, which are not interchangeable with standard halogen units even if the physical mounting looks similar.
Fitment & Compatibility
Tail light design changed between generations of the Fiesta, and facelifted versions within the same generation often use a revised light signature that isn't interchangeable with pre-facelift units. Always confirm the exact part for your specific model year before ordering. Whether you're sourcing a replacement tail lights for your Ford Fiesta from a dealer, specialist, or online marketplace, always check compatibility against your registration or VIN before buying, and confirm you're ordering the correct side — driver's side (RH in the UK) or passenger side (LH in the UK) — since these are not interchangeable.
Ford Fiesta Tail Lights: Generations, Derivatives & Tail Light Type
| Mk7 pre-facelift (2008–2012) | Halogen bulb-based units as standard, with brake and parking light functions on a shared bulb |
|---|---|
| Mk7 facelift (2013–2017) | Genuine Ford full LED tail light option became available, confirmed as a different design from the pre-facelift halogen units and not a direct swap without coding, resistors, or minor adjustments depending on trim |
| Mk8/Mk8.5 (2017–2024) | Genuine Ford OEM Full LED tail lights are available for this generation, alongside a tinted (smoked) lens variant offered as a factory-style upgrade |
