Used Alfa Romeo 155 Brake Light Switch

The Alfa Romeo 155 was produced from 1992 to 1997 with a facelift arriving in 1995, and the brake light switch is a straightforward pedal-box-mounted component present across all variants. The 1995 facelift brought some changes to the interior and running gear, so whether a pre-facelift switch crosses cleanly to a post-facelift car is worth checking directly with the breaker against your registration. Never assume fitment across that 1995 boundary without confirmation.

The brake light switch on the 155 is a pedal-mounted electrical component and is not directly dependent on the braking hardware differences that come with larger engines like the 2.5 V6. Across the petrol range — from the 1.6 through to the 2.5 — the switch itself performs the same function at the pedal box. That said, confirm the specific part number with the breaker against your registration to be sure, as minor variations can exist.

For a brake light switch, trim level makes no difference to fitment — the switch sits on the brake pedal assembly regardless of whether the car is a base 155 or a higher-specification Cloverleaf. You won't find cosmetic differences on this part either, as it's a purely functional electrical component hidden above the pedal. Focus on the year and engine variant when sourcing from a breaker rather than the trim name.

A 1993 car is pre-facelift and a 1996 car sits in the post-facelift period after the 1995 update, so you're crossing a production boundary where detail changes were made to the car. The brake light switch is a simple pedal box component and may well be identical across that boundary, but this is exactly the kind of cross-generation fitment question you should confirm with the breaker quoting against both registrations. Don't assume interchangeability without that check.

The Q4 is the four-wheel-drive variant of the 155 and does exist as a genuine model, but its additional drivetrain complexity relates to the transmission and running gear rather than the pedal box. The brake light switch is a pedal-mounted item and is very likely shared with two-wheel-drive variants, but given the Q4's relative rarity and distinct specification, confirm with the breaker that the part from a standard 155 will cross over to a Q4 before buying.

Give the breaker your full registration number, the year of the car, and the engine size — the 155 was offered with a range of engines from 1.6 to 2.5 V6, and having the exact details helps them pull the right part quickly. Mentioning whether your car is pre- or post-1995 facelift is also useful. The brake light switch is a commonly stocked item on a car of this age, but condition and connector compatibility are worth asking about given that used electrical components can vary.
