Compatibility
These LED bulbs are designed to replace various incandescent bulbs in automotive applications. The cross-reference numbers for compatible sockets include T10, 147, 152, 158, 159, 161, 168, 175, 184, 192, 193, 194, 2825, and W5W.
Common applications include interior map lights, dome lights, license plate lights, parking lights, corner lights, trunk lights, side marker lights, side door courtesy lights, and cargo lights. These bulbs are noted for compatibility with 2013-2015 Infiniti JX35 models.
Always verify your vehicle's original bulb size and type by consulting your owner's manual or checking the existing bulb before purchasing and installing to ensure correct fitment.
Installation Instructions
Safety Precautions
- Always disconnect the vehicle's battery before beginning any electrical work to prevent electrical shock or damage.
- Allow existing bulbs to cool completely before handling, as they can be very hot.
- Wear appropriate protective gear, such as gloves and safety glasses, during installation.
General Installation Steps
- Locate the bulb socket for the specific lighting application you intend to upgrade.
- Carefully remove the old incandescent bulb from its socket by twisting or pulling it out, depending on the socket type.
- Insert the new cciyu LED bulb into the empty socket. LED bulbs are polarity sensitive. If the bulb does not illuminate upon testing, remove it, rotate it 180 degrees, and reinsert it.
- Before reassembling any vehicle panels or covers, test the functionality of the newly installed LED bulb to ensure it is working correctly.
- Once confirmed operational, carefully reassemble all vehicle components that were removed during the installation process.

Operating Instructions
The cciyu 194 T10 5-5050-SMD LED Bulbs are designed for seamless integration with your vehicle's existing electrical system. Once properly installed, they will operate automatically in conjunction with your vehicle's lighting controls.
- Instant On/Off: These LED bulbs provide immediate illumination and turn off instantly, offering faster response times compared to traditional incandescent bulbs.
- Color Output: The bulbs emit an 'Ice Blue' light, providing a distinct and modern aesthetic to your vehicle's interior or exterior lighting.
- Dimming Functionality: If your vehicle's system includes dimming capabilities for the specific application (e.g., dashboard lights), the LED bulbs should respond accordingly. Note that the perceived brightness and dimming range may differ from incandescent bulbs due to the inherent characteristics of LED technology.
Maintenance
cciyu LED bulbs are engineered for durability and a long operational life, requiring minimal maintenance. Adhering to these simple guidelines will help ensure their continued performance:
- Cleaning: Periodically inspect the bulb and socket area for any accumulation of dust or debris. Gently clean with a soft, dry cloth if necessary. Avoid using harsh chemicals or abrasive materials.
- Handling: When handling the bulbs, especially during installation or inspection, avoid touching the LED chips directly. Oils from your skin can potentially affect their performance or lifespan.
- Replacement: In the rare event that an LED bulb fails, replace it with another cciyu 194 T10 5-5050-SMD LED bulb to maintain consistent performance and appearance.
Troubleshooting
Bulb Does Not Light Up
- Check Polarity: LED bulbs are polarity sensitive. If the bulb does not light up after insertion, remove it, rotate it 180 degrees, and reinsert it into the socket.
- Inspect Fuse: Verify the vehicle's fuse for the specific lighting circuit. A blown fuse will prevent the bulb from receiving power. Replace any blown fuses with one of the correct amperage.
- Socket Connection: Ensure the bulb is securely seated in the socket and that the socket contacts are clean and free of corrosion.
Residual Glow (Ghosting)
- In some vehicle electrical systems, a very faint glow may persist in LED bulbs even when the circuit is technically off. This phenomenon, known as 'ghosting' or 'residual glow,' is typically caused by a small amount of residual current in the wiring. While these cciyu bulbs are designed to minimize this, it can occasionally occur and is generally not indicative of a faulty bulb or a significant power drain.
Incorrect Fitment
- If the bulb does not fit into the intended socket, it is likely the wrong size or type for your application. Always confirm the correct bulb size and cross-reference numbers for your specific vehicle before purchase and installation. Refer to your vehicle's owner's manual or a reliable automotive bulb compatibility guide.
