1. Power Monitoring
Certain CANbus systems are designed to monitor the current input of the light bulb under their control. If these systems detect a higher or lower amount of current than the original bulb specification, it can lead to issues. To address this, adding a decoder harness is often the best option. This helps the system accommodate the power demands of the new LED bulb and ensures seamless integration with aftermarket products.
2. Pulse Width Modulation (PWM)
Pulse width modulation (PWM) is a technology utilized to decrease the heat emission of halogen bulbs, extending their lifespan and conserving power during operation. However, it is important to note that LED headlights require a constant and uninterrupted power supply, unlike the intermittent power supply system associated with PWM configurations. Attempting to install LED headlights in a vehicle with PWM settings may result in flickering bulbs or bulbs that eventually turn off. To address this issue, a decoder harness equipped with ample capacitors is employed to stabilize the power flow, ensuring a consistent and uninterrupted current supply to the LED headlights.
