Second Hand Vauxhall Signum Wiper Blades

The Vauxhall Signum uses a driver's side (OS) blade of around 26 inches and a passenger's side (NS) blade of around 18 inches, though you should confirm against your exact registration as there can be minor variations. When buying used blades from a breaker, the wiper arms and blade fitment are what matter most, not the trim level or engine. Always measure your existing blades or check your owner's manual before ordering.

The Vauxhall Signum (2003–2008) shares its platform with the Vectra C and uses the same wiper arm fitment, so blades from a Vectra C of the same generation are generally compatible. The wiper arm hook type and blade length are what determine fitment, not which of the two models the part came from. Confirm the blade lengths match before fitting, and check with the breaker against your registration to be sure.

The Vauxhall Signum ran as a single generation from 2003 to 2008 with no significant facelift that changed the wiper arm or blade specification, so blades from any year within that range should interchange freely. The wiper arm hook type and blade lengths remained consistent throughout the model's production life. Confirm the blade size with the breaker against your registration just to be safe, but year differences within the Signum's run are very unlikely to cause a fitment problem.

No — trim level makes no difference to wiper blade fitment on the Vauxhall Signum; a blade from a base Design car will fit an Elegance or Elite without any issue. The wiper arms and blade attachment are identical across all Signum trims regardless of engine or specification. The only cosmetic difference you might notice between blades pulled from different-spec cars is minor wear or brand, not any structural difference.

Unlikely — the Astra and Zafira use different wiper arm hook sizes and blade lengths compared to the Signum, so these are not a straightforward swap. The Signum shares its blade fitment most closely with the Vectra C rather than the smaller Vauxhall models. Stick to Vectra C or Signum donor cars when sourcing used blades from a breaker to avoid incompatibility.

The Vauxhall Signum does not have a rear wiper — it is a saloon/hatchback-style car whose tailgate design was not fitted with a rear wiper motor or arm from the factory on any variant. If you are looking for a rear wiper, you may be thinking of a different model such as the Vauxhall Zafira or Astra estate. For the Signum, only front wiper blades (driver's and passenger's side) are relevant.
