Mazda Vehicle Bulb Guide
Fitment Data Awaiting Verification
The tables below have not yet been verified against Mazda documentation for each market, chassis, model year, body style, and trim. Treat them as reference only, not a confirmed shopping list. Do not select a replacement bulb from the model and year alone.
Before purchasing, confirm your vehicle’s market or regional specification, chassis/model code, exact model year, body style, trim, and factory halogen, HID, or LED lighting. Check the markings on the existing bulb and the owner’s manual for your exact vehicle. If a festoon bulb is listed without a length, measure the existing bulb before ordering. Where year ranges overlap, confirm your exact vehicle configuration.
Grouped model names require separate verification: Headings such as Mazda 2 / Demio, Mazda 3 / Axela, and Mazda 6 / Atenza do not establish that the same bulb fits every named model, body style, or regional version. Confirm the exact model, market, and chassis before using a listed bulb type.
If you need help, send Riglow those details plus clear photos of the existing bulb, its markings, and connector. Factory LED entries do not identify a replaceable bulb; confirm the applicable replacement method before purchasing.
Find the Correct Bulbs for Your Mazda
Use this guide to identify the most common headlight, fog light, parking light, brake light, reverse light, indicator, and interior bulbs used in popular Mazda vehicles. Always verify your bulb type before purchasing, as specifications may vary by year, trim level, and market.

These links match socket or length labels in our product listings, not verified Mazda vehicle fitment. Confirm the original bulb type and each lamp location before choosing. Check connectors, retainers, housing clearance, electrical requirements and suitability for the intended lighting function. CANBUS labels do not guarantee error-free or flicker-free operation.

| P21/5W / BAY15d — qualified brake/tail shopping candidate |
Riglow Premium Red LED — 1157 / BAY15d. Riglow confirms separate 5W dim-tail and 15W bright-brake modes for this variant. This is a qualified shopping reference, not verified Mazda vehicle fitment. Confirm the original bulb marking, BAY15d base, two bottom contacts, staggered locating-pin heights, polarity, voltage, housing clearance and red output suitability for the lamp assembly. Verify both tail and brake functions after installation. This confirmation does not apply to the separate 7443 variant. Sold individually; order two for a pair. |
| P21W / 1156 / BA15s — reverse-light candidate |
1156 BA15S White LED. Confirm single contact, locating pins, electrical requirements, clearance and suitability for the reverse-light assembly. |
| PY21W / BAU15s — amber indicator candidate |
24SMD3030 Series — Amber / BAU15S / PY21W. Sold individually; order two for a pair. Confirm the base, contact layout, locating pins, circuit requirements, housing clearance and amber output suitability for the indicator assembly. Additional components may be required; CANBUS support does not guarantee freedom from hyperflashing, flicker or dashboard warnings. |
| WY21W / T20 / 7440 — amber indicator candidate |
24SMD3030 Series — Amber / 7440. Shopping reference based on Riglow’s supplied WY21W/T20/7440 cross-reference, not verified Mazda fitment. Confirm the original bulb marking, base geometry, contact layout, circuit requirements, housing clearance and amber output suitability for the indicator assembly. Sold individually; order two for a pair. Additional components may be required; CANBUS support does not guarantee freedom from hyperflashing, flicker or dashboard warnings. |
The P21W-to-1156 and WY21W/T20/7440 shopping references above use Riglow’s supplied cross-references alongside the product listings. They do not establish identical electrical ratings or verified vehicle fitment. The linked Premium Red 1157/BAY15d brake/tail candidate has Riglow-confirmed 5W tail and 15W brake modes; these are the LED's stated ratings, not a claim that it is a 21W/5W filament bulb. Dual-intensity confirmation does not establish vehicle fitment, error-free operation or compatibility of the separate 7443 variant. Confirm the socket, contacts, locating pins, electrical requirements and intended lamp function before ordering. Do not substitute the linked BA15s 1156 bulb for a BAU15s/PY21W indicator. The BAU15s/PY21W and 7440 amber links are separate socket options, not interchangeable recommendations. Combined 7443/WY21W product labels are not used to establish compatibility here. For festoon entries with no length, measure the original bulb before selecting a size. Factory LED entries do not establish a replaceable bulb or compatibility with the linked conversion kits.
