Lexus RX Tail Lights: Specs, Fitment & Common Faults
On the RX, unlike the headlights, tail lights genuinely lack a butyl seal, meaning the likely culprit is a rotted bulb socket rubber seal — plus a genuine finding about a drainage channel that can get blocked with dirt.

OEM Part Number: confirm via VIN — tail light (aftermarket) Abakus 224-1306L-US
| Tail lights (aftermarket) | Abakus 224-1306L-US (left, without bulb holder, right-hand pair 224-1306R-US) |
|---|---|
| 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. |
Lexus RX Tail Lights: More Wiring Behind There Than Most People Assume
The Lexus RX's tail light units do a lot in a small space, typically bundling brake, indicator, reversing and rear fog light functions together — so when something goes wrong electrically, more than one function can fail at once, and "faulty tail light" is rarely a precise diagnosis on its own.
Lexus RX Tail Lights: What It Does
Beyond basic rear visibility, tail light units on the RX 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
Lexus RX 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 RX, 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 Lexus RX 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.

A Genuinely Specific, Real Finding Worth Knowing About Tail Light Condensation — Lexus RX Tail Lights
If you're seeing condensation in a tail light, this is genuinely worth knowing: unlike the headlights, which use a butyl seal that can sometimes be reopened with gentle heat, the tail lights don't have this same type of seal. This means the most likely culprit specifically is a rotted rubber seal around one of the bulb sockets, rather than the main lens seal itself.
It's also genuinely worth knowing a practical, temporary workaround if a tail light actually fills with water rather than just fogging: simply opening and closing the boot or tailgate again can help drain the water back out. It's also worth knowing that warranty coverage for this kind of condensation genuinely varies between cases, worth checking your specific situation with a dealer.
