Fitment checklist for Alfa Romeo

Reflector vs projector

LED bulbs in a halogen reflector scatter light and are not road-legal in most markets. Projector housings or full LED units are the compliant route.

Coding and CAN bus

Many cars flag an LED as a bulb-out failure unless the unit has CAN-bus resistors or the module is coded.

Aim after fitting

A new housing must be beam-aimed or it fails inspection and dazzles oncoming traffic.

Frequently asked questions

Are LED bulb conversions legal?
In most of Europe, the UK and Australia, retrofitting LED bulbs into a housing type-approved for halogen makes the vehicle non-compliant. Rules differ by market — check yours before buying.
Can a hazed headlight be restored?
Yes. Wet-sanding and a UV-stable clear coat restores output for a fraction of a new housing.
Are Alfa Romeo lighting parts expensive?
Alfa Romeo sits in the premium tier, so genuine parts carry a premium. OE-supplier brands make the same components without the badge markup.
