When incandescent bulbs are replaced by LEDs in automotive headlights, the vehicle’s on-board computer (OBC) may generate an error because LEDs consume much less power than incandescent bulbs.
In addition to generating error messages, replacing incandescent turn signal bulbs with LEDs in vehicles often causes the turn signal frequency to increase a phenomenon known as “hyper flashing”. This occurs because automotive flasher relays and on-board computers are designed to detect failures by monitoring the current draw: when it falls below a certain threshold (as it does with energy-efficient LEDs), the system interprets this as a missing or burned bulb, and increases the blink rate to alert the driver of a problem.
To solve these problems, they usually use LED load resistors.
LED load resistors and “dummy resistors” are commonly used terms for the same type of solution in automotive LED retrofits. Their primary role is to simulate the current draw of a traditional incandescent bulb, which is much higher than that of an LED, allowing the vehicle’s electronic systems to function correctly after upgrading to LEDs.
Gambeks has developed a universal electronic controller module that replaces load resistors and solves all of these problems, while remaining cool and fully controlling the proper operation of the vehicle’s computer.
Our company has developed an innovative intellectual module” that solved those problems! Comparison of our smart module with a load resistor
