A Genuinely Important UK Rule Worth Knowing Before You Buy — Citroen C5 Aircross Headlights
If your C5 Aircross has factory-fitted halogen headlamp housings, converting them to fit LED bulbs is treated as a definite MOT failure under the current inspection manual — this isn't a grey area or a minor advisory, since a housing designed for halogen doesn't distribute an LED bulb's light output correctly, which can genuinely dazzle oncoming drivers. If you want a genuine LED upgrade, the correct route is a complete headlight unit designed for LED from the factory, not a bulb swap into an existing halogen housing.

Citroen C5 Aircross Headlights: What It Does
The Citroen C5 Aircross's headlight unit job is positioning the main and dipped beam bulbs (or LED/matrix modules on higher trims) to light the road without dazzling oncoming drivers. That housing frequently also contains the daytime running light and front indicator, which is exactly why part numbers and repairs here can get complicated.
Citroen C5 Aircross Headlights: Generations, Derivatives & Headlight Type
| Initial range (2018–2021), by option | Genuinely four separate possible configurations depending on build date and options: Halogen only, Halogen plus LED, or full LED — always confirm your exact spec via VIN rather than assuming by trim name alone |
|---|---|
| Facelift (2021+) | LED only across the board — the facelift standardised on LED, removing the halogen options that existed on the earlier range |
| Fitment note | Cars with any halogen headlights genuinely need beam deflector stickers for driving on the other side of the road in mainland Europe; many (but not all) LED-equipped cars are exempt if the beam pattern or menu-adjustable settings mean deflectors aren't required — check your specific handbook rather than assuming |
