Frequently Asked Questions

Q: What colors are available for these 5mm F5 LED bulbs?

A: These LED bulbs are available in six colors: White, Warm White, Red, Green, Blue, and Yellow. Simply select your preferred color at checkout. Each pack contains 10 bulbs of the same selected color.

Q: What voltage and current do these 5mm LEDs require?

A: These LEDs operate at 3V with a forward current of 20mA. If you're connecting them to a higher-voltage power source (such as 5V or 12V), use an appropriate current-limiting resistor to protect the diodes and ensure stable, long-lasting performance.

Q: Can I use these LED bulbs for outdoor decorations or car lighting?

A: Yes! These F5 flux LEDs are well-suited for DIY car accent lighting, boat and bike projects, holiday decorations, billboard signage, and more. Their wide 110–120° viewing angle ensures broad illumination, and the water-clear lens delivers sharp, vivid color output.

Q: How do I identify the correct polarity for installation?

A: Each LED diode features clear polarity markings to help you distinguish the anode (+) from the cathode (–). The longer leg is typically the anode. Always connect with the correct polarity to avoid damaging the LED.
