Frequently Asked Questions

Q: Are these T10 COB LED bulbs compatible with my car?

A: These bulbs use the standard T10 (W5W / 194) base and fit most vehicles that accept T10 sockets for interior reading lights, dome lights, license plate lights, and trunk lamps. The included T10 and festoon dome adapters broaden compatibility further. Always verify your vehicle's socket type before purchasing.

Q: What is the difference between the 16SMD, 24SMD, 36SMD, and 48SMD versions?

A: The SMD count refers to the number of LED chips on the COB array. More chips generally mean greater brightness output. The 48SMD variant is the brightest option, while the 16SMD is the most compact. Choose based on the size of your socket housing and the brightness level you prefer.

Q: Do these T10 LED bulbs require any special tools or wiring for installation?

A: No special tools or wiring are needed. These are plug-and-play T10 LED bulbs — simply remove the old bulb and insert the new one. If the bulb doesn't light up, reverse its polarity (flip it around) in the socket. Always ensure the car is switched off before installation.

Q: How long do these COB LED car bulbs last?

A: These bulbs are rated for up to 50,000 hours of use. They also carry a 3-year warranty from the manufacturer, giving you long-term peace of mind.
