T10 / T15 LED Bulbs: 194 W5W & 921 W16W Interior, Marker & Reverse Light Replacements
The T10 is the most widely used miniature wedge bulb in vehicle interior and marker lighting, while its larger sibling the T15 handles reverse and backup duties. The T10 (194 / W5W) drives interior dome, map, license-plate, and side-marker lights; the T15 (921 / W16W) is a wider, brighter wedge used for reverse and backup lights. MIDCARS manufactures both in-house — standard, 360°, PC-cover-protected, and dual-color switchback versions — to cover every replacement and upgrade need.
T10 vs T15: What's the Difference?
| Feature | T10 (194 / W5W) | T15 (921 / W16W) |
|---|---|---|
| Wedge size | Small wedge, ~10mm | Larger wedge, ~15mm |
| Typical use | Interior dome, map, license plate, side marker | Reverse / backup light |
| Brightness | Low-to-mid output | Higher output for rear visibility |
| Common cross-reference | W5W, 194, 168 | W16W, 921, 912 |
How to Choose the Right T10 / T15 LED Bulb
- Confirm the wedge size. T10 for interior/marker, T15 for reverse — the two are not interchangeable.
- Voltage. We build 6V, 12V, and 24–32V versions for motorcycles, cars, and commercial vehicles.
- Beam pattern. 360° versions light the whole fixture; PC-cover versions protect the LEDs and project a cleaner beam.
- Color temperature. 6500K white, 3000K warm white, or amber — and dual-color switchback for white/amber running-and-signal use.
- CANbus or non-CANbus. CANbus versions stop dashboard warnings on vehicles with lamp-out detection.
Common Applications
- Interior dome, map, and reading lights

Can I use a T15 in a T10 socket?
No. The T15 wedge is physically wider than the T10, so it will not seat correctly in a T10 socket. Match the wedge size to the socket before ordering.
Which is brighter, T10 or T15?
The T15 is the brighter of the two, designed for reverse lights where rear visibility matters. The T10 is sized for interior and marker lighting where lower, diffused output is preferred.
Do you offer 24V versions for trucks?
Yes. We build 24–32V T10 and T15 versions for trucks, buses, and commercial vehicles, alongside standard 12V and 6V motorcycle versions.
