Cadillac Vehicle Bulb Guide

Cadillac Bulb References for Barbados Drivers

Original headlamp/front-fog findings checked directly against three NISSEI/POLARG records on 22 October 2026, across three model groups. Imported-vehicle catalogue scopes are not proof of Barbados, US 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

CTS, 2003–2007, AD32･33

H11 or D1S HID low; HB3/9005 high; H10※ fog. Low prints 12V55W or 85V35W, part 0-20 or an incomplete HID alternative. High prints 12V60W(65W) / 0-05. Fog prints 12V42W with part blank. Preserve the exact AD32･33 scope and original halogen/HID alternatives; do not infer every trim, body or low/high/fog pairing. H10 is not automatically interchangeable with 9005 despite similar-looking products. POLARG CTS record.

Escalade, 2004–2007, chassis not supplied

HB4/9006 low (12V51W(55W) / 0-06); HB3/9005 high (12V60W(65W) / 0-05); fog blank. Do not invent chassis or expand to every Escalade body, ESV/EXT or adjacent year. This is the record listed in POLARG’s Cadillac index; the separately encountered Chevrolet-index placement is not evidence of Chevrolet fitment. POLARG Cadillac-index Escalade record.

XLR, 2004 onward, X215

D1S HID low (85V35W, part blank); separate high and fog blank. Blank entries do not establish absent functions or independent replaceable high-beam/fog bulbs. Keep exact X215 scope rather than all packages or related platforms. POLARG XLR record.

Source Qualifications

Only original headlamp/front-fog positions were checked, not brake/tail, indicators, interior or other lamps. Keep the CTS H10※ marker unresolved and review original notes and actual assemblies. Blank fields do not establish absent functions or equipment. Preserve incomplete CTS D1S part alternative and blank XLR D1S part rather than borrowing a D2S reference. D1S is a distinct original bulb type, not proof of interchangeability with other HID or LED products.

Periods are year-only, not exact production months. Production and factory-lighting identification matter, not registration year alone. An open-ended source date does not establish continued production, later generations or unchanged equipment. Preserve literal chassis and model scopes without inventing body/trim coverage. Halogen/HID alternatives do not establish interchangeable bulbs or every assembly combination. Shared platforms, regional aliases or similar names alone do not establish fitment. The current Cadillac index does not establish applications for unlisted model families.

Identify Your Cadillac 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 Cadillac fitment by this page.
