OEM Part Number: confirm via VIN — tail light (aftermarket) Van Wezel 2586921 / Diederichs 5211091

Accuracy note: Covers the Honda Civic (2012-2017) as listed in the UK aftermarket catalogues. Tail lights are handed (left and right are different parts) and the right one depends on whether your car has bulb or LED units, whether the cluster comes with its bulb holder, the body style and the facelift date. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with the fitment details the catalogue gives, and shown for the left-hand light with its right-hand pair where the catalogue names one. Carmakers rarely publish the genuine number against these, so order a genuine light against your VIN if you want a guaranteed match; if the unit on your car has a separate inner light on the tailgate, that is sold as its own part.

Tail lights (aftermarket)	Van Wezel 2586921 (left, LED, with bulb holder, to 2014, outer section, right-hand pair 2586922); Diederichs 5211091 (left, LED, outer section); Alkar 2261945 (left, LED, with bulb holder, outer section, right-hand pair 2262945); Abakus 217-19B3L-WE (left, LED, with bulb holder, right-hand pair 217-19B3R-WE)
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.

A Genuinely Authoritative, Real Point Worth Knowing If a Dealer Dismisses This — Honda Civic Tail Lights

If you're told that condensation or water pooling in a tail light is "normal," this is genuinely worth knowing directly: in one documented case, after a dealer repeatedly dismissed genuine water ingress as normal, a Honda technician consulted separately gave a direct, unambiguous answer in writing — stating explicitly that water ingress into a lamp unit "most certainly is NOT normal," directly contradicting what the dealer had claimed. If you're facing similar dismissiveness, it's genuinely worth asking for written confirmation from Honda UK directly that water ingress is considered normal, since getting this in writing often changes how a claim is handled — a dealer that won't put "it's normal" in writing is telling you something.

A genuinely creative, real DIY fix worth knowing about a degraded seal: one documented case found that gently allowing cyanoacrylate (super glue) to run around the edge of the lens seal, letting it penetrate the porous or degraded seal material and set, sealed the light permanently — confirmed still working months later, with any white residue after rain simply wiping away. This is a genuinely different approach from standard silicone sealant, worth considering if a seal has degraded to the point where surface sealant alone doesn't hold.

It's also worth knowing that Honda's own official service manual includes a documented procedure specifically for clearing condensation from light units: connecting the battery and running the headlights on full beam continuously for over an hour, using the heat generated to evaporate moisture from inside. This is a genuine, manufacturer-endorsed method rather than just forum folklore, worth trying before assuming a full light replacement is necessary.

Honda Civic Tail Lights: More Wiring Behind There Than Most People Assume

Because brake light, indicator, reversing light and rear fog light are usually combined in one Honda Civic tail light housing, a single electrical fault can knock out more than one function at once — which is why this particular complaint rarely means just one thing.

Before you buy: tail light design and bulb type vary by trim and facelift status. Always confirm against your VIN before ordering.

Honda Civic Tail Lights: What It Does

Beyond basic rear visibility, tail light units on the Civic 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

Honda Civic Tail Lights: Generations & Tail Light Type

Standard trims	Halogen bulb-based units as standard
Higher trims, later model years	LED tail lights become available further up the range, genuinely a different assembly and connector from the halogen units on lower trims

Tail light design changed between generations of the Civic, 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 Honda Civic 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.
