Product Features
31mm Festoon Design with Pointed Metal Contacts
Our 31mm LED festoon bulbs feature metal end caps with pointed contact tips. These contacts connect with the spring contacts inside compatible festoon lamp holders, providing a practical connection structure for automotive door lights.
Checking the original bulb length and contact arrangement helps identify the correct replacement specification.
Configurable SMD LED Chips
We offer 3014 and 4014 SMD LED chip options, with adjustable chip quantities and arrangements. Each LED chip is rated at 1W, so the total bulb power depends on the number of chips used.
The LED matrix configuration can also be adjusted to provide different brightness configurations. This gives you more control over the product specification when selecting bulbs for different lighting requirements.
Aluminum Heat-Dissipation Structure
The bulb uses an aluminum backing board and heat sink to transfer and spread heat generated by the LED chips. Its metal end caps also form part of the heat-dissipation structure.
CANBUS Circuit and Non-Polarity Design
Our festoon LED bulb series incorporates an integrated CANBUS circuit and non-polarity design.
The CANBUS circuit is designed to reduce compatibility issues associated with vehicle bulb monitoring systems. The non-polarity design eliminates the need to match positive and negative orientation during installation.
Actual compatibility still depends on the vehicle's electrical system and lamp configuration.
