Why Choose 3030 SMD?
The 3030 SMD chip offers a superior balance of size, efficiency, and lumen output compared to older 3030 chips. Our configuration of 15 chips ensures even light distribution, maximum brightness, and long-term durability for demanding automotive environments.
Note: Some modern vehicles with CAN-BUS systems may require an additional load resistor to prevent hyper-flashing on turn signals. Please check your vehicle’s compatibility.
