How many cancellers do I need?

You will need one RGB Fog Warning Canceller module per vehicle to regulate the signal and prevent flickering in your multicolor fog lights. This module is sold individually.

What vehicles typically require this canceller?

Vehicles from manufacturers like BMW and Audi often use Pulse Width Modulation (PWM) to control the brightness and lifespan of their halogen bulbs and DRLs. This canceller is designed to regulate the signal in these vehicles to ensure proper operation of aftermarket multicolor fog lights.

What is Pulse Width Modulation (PWM)?

Pulse Width Modulation (PWM) is a technique used by some vehicle manufacturers to control the brightness and lifespan of halogen bulbs and DRLs. It involves alternating the current, which can cause flickering in some aftermarket multicolor fog light kits that require a continuous current to operate correctly.

Product Details

Overview. RGB Fog Warning Canceller Module Some vehicle manufacturers such as BMW and Audi are using alternating current on new cars to extend the lifetime of halogen bulbs. This is also often the case on DRLs, to achieve a lower brightness during the day. Specifically, this is called Pulse Width Modulation. Some Multicolor Fog Light kits require continuous current to operate correctly. If installed on a circuit with alternating current, the lights will flicker very quickly when the vehicle is turned on. The solution for this is the RGB Fog Warning Canceller Module. To regulate the signal, you will need one module.Overview.RGB Fog Warning Canceller ModuleSome vehicle manufacturers such as BMW and Audi are using alternating current on new cars to extend the lifetime of halogen bulbs.
