Alfa Romeo Vehicle Bulb Guide

Alfa Romeo Bulb References for Barbados Drivers

Original headlamp/front-fog findings checked directly against 14 NISSEI/POLARG records on 22 October 2026, across 10 model groups. Imported-vehicle catalogue scopes are not proof of Barbados, UK, Italian or every right-hand-drive application. Match original market, production period, literal chassis, body and factory lighting to the actual vehicle. This is not a confirmed shopping list or Riglow LED-conversion compatibility guide.

POLARG Headlamp and Front-Fog Findings

145, 1996–2001, 930

H1 low/high; H3※ fog. POLARG 145 record.

147, 2001 onward, 937

H7 low/high; H1※ fog. Do not infer GT findings merely from the shared printed code. POLARG 147 record.

155, 1992 onward, 167

H1 low/high; H3※ fog. POLARG 155 record.

156, 1998 onward, 932

H7 or D2S HID low; H1 high; H1※ fog. Preserve original halogen/HID alternatives without assuming interchangeable bulbs or every assembly pairing. POLARG 156 record.

159, 2006 onward, 939, halogen specification

H7 low/high; H1※ fog. POLARG 159 halogen record.

159, 2006 onward, 939, HID specification

D1S HID low (85V35W, part blank); H1 high; H1※ fog. Keep the high-beam distinction from halogen H7 and do not assign a D2S part to D1S. POLARG 159 HID record.

164, 1990–1992, literal 164

H4 low; separate high blank; H3※ fog. Preserve printed vehicle code matching the model number rather than invent a longer code. POLARG earlier 164 record.

164, 1992 onward, literal 164

H1 low/high; H3※ fog. Preserve the H4-to-H1 change and year-only 1992 overlap. POLARG later 164 record.

166, 1999 onward, 936

H7 or D2S HID low; HB3/9005 high (12V60W(65W) / 0-05); H3※ fog. POLARG 166 record.

GT, 2004 onward, 937

H7 or D2S HID low; H1 high; fog blank. Do not fill fog from 147 or GTV; preserve distinct source model scope. POLARG GT record.

GTV, 1996–2003, 916

HB3/9005 in both low and high fields (each 12V60W(65W) / 0-05); H3※ fog. Preserve literal HB3 low rather than silently substitute HB4 or another type. Verify actual assembly and bulb markings. POLARG earlier GTV record.

GTV, 2003 onward, 916

HB3/9005 in both low and high fields (each 12V60W(65W) / 0-05); H3※ fog. Keep separate source revision despite matching findings. POLARG later GTV record.

Spider, 1996–2003, 916

HB3/9005 in both low and high fields (each 12V60W(65W) / 0-05); fog blank. Preserve printed low/high types without guessing corrections; do not copy GTV H3 fog because of shared code or design. POLARG earlier Spider record.

Spider, 2003 onward, 916

HB3/9005 in both low and high fields (each 12V60W(65W) / 0-05); fog blank. Preserve separate period and exact 916 source scope, not all later Spider-name applications. POLARG later Spider record.

Source Qualifications

Only original headlamp/front-fog positions were checked, not brake/tail, indicators, interior or other lamps. Keep all ※ markers unresolved and review original notes and actual assemblies. Blank high/fog fields do not establish absent functions or equipment; H4 in a low field does not establish absent high beam. Ratings/parts generally print H4 12V60/55W / 0-02; H1 12V55W / 0-08; H3 12V55W / 0-13; H7 12V55W / 0-11. Preserve literal HB3 12V60W(65W) rating order and HB3 low/high placements. D2S prints 85V35W / 3502K; D1S prints 85V35W with part blank. D1S and D2S are distinct, not interchangeable replacements.

Periods are year-only, not exact production months. Overlapping 1992 and 2003 revision years require actual production and factory-lamp identification, not registration year alone. Open-ended dates do not establish continued production, newer generations or unchanged equipment. Preserve literal chassis, separate body/model scopes and revision records without inventing all trim coverage. Halogen/HID alternatives do not establish interchangeable bulbs or every low/high/fog combination. Shared names or codes do not establish vehicle fitment; the current index does not establish unlisted Alfa Romeo model families.

Identify Your Alfa Romeo and Its Lighting

Right-hand drive alone does not confirm fitment. Check original regional specification, exact chassis, body, production period, trim and factory halogen/HID/LED package. Confirm existing bulb markings and socket against vehicle-specific documentation and clear photos. Do not assume other lamp locations share the headlamp technology.

Replacement and LED Conversion Checks

Confirm exact bulb type, connector, locating tabs, retention, voltage, dust-cap/cooling clearance and intended function before choosing a product. Original bulb findings do not establish Riglow conversion compatibility or beam performance. CANBUS labels do not guarantee freedom from warnings, flicker or electrical issues. Similar names or connectors are insufficient compatibility evidence; the exact LED maker must explicitly support the original type. Factory HID/LED equipment needs its own verified solution.

Ask Riglow for help with original market, model/chassis, production year, body, lighting package and clear photos of the bulb, markings and connector. Use the main bulb guide for qualified shopping references only after confirming the original type. No product is confirmed as Alfa Romeo fitment by this page.
