More Wiring Behind There Than Most People Assume
The BMW 3 Series's tail light unit combines several jobs in one housing — brake, indicator, reversing and rear fog light — so a single fault can knock out more than one function at once, and "the tail light's not working" isn't really one specific problem.
OEM Part Number: confirm via VIN — tail light (aftermarket) Alkar 2031843 / Van Wezel 0560923
| Tail lights (aftermarket) | Van Wezel 0560923 (left, LED, with bulb holder, inner section, right-hand pair 0560924); Van Wezel 0593923 (left, with bulb holder, to 2022, inner section, right-hand pair 0593924); Diederichs 1219193 (left, LED, with bulb holder, inner section); Alkar 2031843 (left, LED, with bulb holder, outer section) |
|---|---|
| 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. |
M Shadowline trim uses a darker-tinted tail light lens compared with standard trims — confirm which finish your car has, since these are genuinely different parts despite looking similar at a glance.

This video is of an earlier generation of the same model; the job is similar but the light fittings and clips can differ slightly.
BMW 3 Series Tail Lights: What It Does
Beyond basic rear visibility, tail light units on the 3 Series 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.
BMW 3 Series Tail Lights: Generations, Derivatives & Tail Light Type
| E90/E92/E93, standard trims | Halogen bulb-based units as standard, in a conventional red lens design |
|---|---|
| E90/E92/E93, M Performance | Genuine factory "Black Line" tail lights — a smoked/blacked-out lens finish confirmed as a real BMW OEM part, not just an aftermarket style, giving a more aggressive rear appearance |
| F30/F80 M3, M Performance option | Black Line tail lights continue to be offered as a genuine factory or dealer-fit accessory on this generation, distinct from the standard clear/red lens design |
| Current generation, higher trims | Full LED tail lights with a distinct light signature become standard, genuinely not interchangeable with the halogen units on lower trims |
Fitment & Compatibility
Tail light design changed between generations of the 3 Series, 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 BMW 3 Series 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.

Confirmed: A Genuine Official Bulletin Worth Knowing About — BMW 3 Series Tail Lights
If condensation has appeared inside a tail light, this is genuinely worth knowing directly from an official BMW service bulletin covering this generation specifically: these tail lights use waterproof membrane technology, which deliberately allows naturally occurring condensation and air to escape without letting excess water or dirt enter. The official bulletin includes example images distinguishing normal condensation, appearing along the edges of the lens, which requires no correction at all, from excessive water entry, which appears across the entire lens rather than just at the edges and does require attention.
It's also genuinely worth knowing that a confirmed UK recall covering certain models from this era addressed a wiring fault where frictional corrosion on a power distributor plug could cause the car to completely lose power, shutting down all lighting including hazard lights, brake lights, and headlights — worth checking your specific VIN against the official recall register if your car falls within the affected range.
