Second Hand Vauxhall Signum Headrest

The Signum was produced from 2003 to 2008 as a single generation, so headrests from across that full production run are your starting pool of potential matches. However, fitment depends heavily on trim level, as seat designs varied between grades, so a headrest from the same trim level is always the safest choice. Confirm the exact trim of both the donor and your car with the breaker against your registration before buying.

Yes, trim level is one of the most important factors for Signum headrests because seat upholstery, headrest shape, and mounting styles varied between grades such as Design, Elegance, and Vector. A headrest from a different trim may physically fit the seat post but look noticeably different in colour, material, or profile. Always tell the breaker your exact trim so they can match from the correct seat type.

Yes, front and rear headrests are not the same part; they differ in size, shape, and post spacing, so you need to specify which row and which position you are replacing. For rear seats, also confirm whether you need a nearside (NS/left), offside (OS/right), or centre headrest, as these can differ too. Give the breaker the full details — row and position — to make sure the replacement matches correctly.

The Signum received a facelift in 2005 which updated interior trim details on some grades, meaning seat and headrest specifications may have changed across that boundary. Pre-facelift (2003–2005) and post-facelift (2005–2008) headrests may or may not interchange depending on your specific seat type and trim level. Route this directly to the breaker, quoting your registration and the donor vehicle's registration, so they can verify whether the part is a genuine match.

No — engine choice has no bearing on headrest fitment whatsoever, as headrests are purely an interior trim part and are the same regardless of whether the car had a petrol or diesel engine. Focus your search on generation, trim level, and seat position rather than drivetrain. Any breaker who asks about your engine for this part is simply using it to identify your car on their system, not because it affects the part itself.

The Signum shared its platform with the Vectra C and some interior components are common between the two, but seat designs and headrests do not always match directly because the Signum had a distinct interior focused on rear passenger comfort with different seat profiles. There may be some crossover depending on trim and seat type, but this is not guaranteed. Ask the breaker to check compatibility across both models against your specific registration before committing to a purchase.
