Mercedes-Benz Vehicle Bulb Guide
Fitment Data Awaiting Verification
The tables below have not yet been verified against Mercedes-Benz 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 the market or regional specification, chassis/model code, exact model year, body style, trim, and factory halogen, HID, LED, or Multibeam LED lighting configuration. Check the existing bulb markings and the owner’s manual for your exact vehicle. Measure the existing festoon bulb where no length is listed. Resolve overlapping year ranges using your exact vehicle configuration; open-ended “Present” ranges do not establish verified coverage of later model years.
Lighting packages and grouped models require separate verification: W205, W213, and GLC X253 entries marked H7 / LED do not identify the applicable factory headlamp packages. Other single bulb assignments must not be assumed to cover every lighting option in a generation. The grouped GLE W166 / ML W166 heading does not establish shared fitment across all named models and configurations. For Sprinter, confirm the exact chassis, body configuration, market, and factory lighting before using a listed bulb type.
Entries marked “trim dependent” do not identify which configuration applies. Factory LED entries do not establish an individually replaceable bulb; confirm the replacement method. LED or Multibeam LED headlights do not establish that other light locations use LEDs. Send Riglow the vehicle details and clear photos of the bulb, markings, and connector if you need help.
Find the Correct Bulbs for Your Mercedes-Benz
Use this guide as an unverified reference for headlight, fog light, parking light, brake light, reverse light, indicator, and interior bulb listings. Confirm the factory lighting at each location before ordering rather than assuming fitment from a model name, chassis code, or year.

Popular Mercedes-Benz LED Upgrades
Upgrade your Mercedes-Benz with premium LED lighting for improved visibility, modern styling, and longer lifespan.
Browse Options for Your Confirmed Bulb Type
These links match socket or length labels in our product listings, not verified Mercedes-Benz 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.

| H11 — H8/H9 multi-fit use is conditional |
K62 H11 · X8 H11 · V8 H11. The updated Riglow LED bulb reference chart treats H8/H9/H11 as a conditional family, not blanket equivalents. For an H8 or H9 original bulb, use a multi-fit LED only when that exact LED manufacturer's compatibility listing explicitly includes the original size. These H11 links alone do not establish H8/H9 support. Confirm original markings, base and connector, retention, dust-cap space, cooling clearance, voltage and beam pattern. H11B and H16 require their own explicitly supported solutions. Factory LED assemblies are not established as compatible with these kits. |

| 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 Mercedes-Benz 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. |
| 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 Mercedes-Benz 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. |
The WY21W/T20/7440 shopping reference above uses Riglow’s supplied cross-reference alongside the product listing. It does not establish identical electrical ratings or verified vehicle fitment. The BAU15s/PY21W and T20/7440 amber links are separate socket options, not interchangeable recommendations. Combined 7443/WY21W product labels are not used to establish compatibility here. H8/H9/H11 is a conditional LED family in Riglow’s updated reference chart dated 14 October 2026: a shared connector alone does not confirm fitment, and the exact LED maker must explicitly list the original size. The chart is an identification reference, not a vehicle-fitment or stock list; it does not establish halogen interchangeability. 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. 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.
Recommended LED Conversions
Verification required: The conversion suggestions below are not confirmed fitment recommendations. Confirm the original bulb type, connector, available clearance, and your vehicle’s lighting configuration before selecting an upgrade.

Electrical compatibility requires verification: Do not treat a CANBUS-compatible label as a guarantee of error-free or flicker-free operation. Confirm compatibility of the selected bulb with your exact vehicle and light location before ordering.
Important Note
Bulb fitment may vary based on vehicle year, trim package, factory options, and regional specifications. Verify each light location separately; do not assume a vehicle is fully LED from its model year or headlight equipment. If you are unsure which bulb fits your Mercedes-Benz, contact Riglow Auto LED Lighting with:
- Exact vehicle model and chassis code (e.g. W205, W213)
- Exact model year and body style or van body configuration
- Trim level and market or regional specification
- Factory halogen, HID, LED, or Multibeam LED lighting configuration
- Clear photos of the existing bulb, markings, and connector
Our team will help you find the correct LED upgrade.
