How many bulbs are included in the pack?
This pack contains 10 individual bulbs.
Do I need special tools to install these?
No tools are required, though a clean cloth is recommended for handling the glass to prolong bulb life.
What is the base type for this model?
This model uses a W2.1x9.5d wedge base.
Troubleshooting

Verify the vehicle is using a 24V system and ensure the bulb is fully seated in the wedge socket.

Pros and Cons
Pros
- Reliable OEM performance for commercial vehicles
- Road-legal ECE certification
- Impressive 3,000-hour service life
- Ideal for multiple lighting applications
Cons
- Not compatible with standard 12V passenger car systems
- Limited to specific 24V heavy-duty applications
- Glass bulb requires careful handling to avoid skin oils
Setup, Compatibility & Care
Installation of the W2.1x9.5d base is a simple plug-and-play process; simply pull the old bulb from the socket and press the new one firmly into place. Ensure the vehicle's ignition is turned off before replacing any bulbs to prevent short-circuiting the electrical system. When handling these bulbs, avoid touching the glass directly with bare fingers, as natural skin oils can cause hot spots and reduce the lifespan of the glass envelope—using a clean cloth or gloves is recommended. These bulbs are strictly for 24V systems; installing them in a 12V system will result in extremely dim or no light output, and installing in higher voltage systems may cause immediate failure.
