Pulse Width Modulation is commonly found in the electrical systems that operate the headlight circuit in many modern vehicles.
When it comes to HID or LED upgrades, this can cause flickering in the new setup.
Unsure if you need these for your vehicle upgrade?
Check the rule of thumb guide in the tech specs below for information to assist in making the best decision.
GTR Lighting recommends installing the PWM Modules if you are uncertain, as they will not cause harm even if unnecessary.
Anti-Flicker: Their powerful Capacitors system absorbs the pulsing current from factory wiring and smooths it out before it causes flickering in your LED bulbs or HID ballasts.
In most cases, they can be used alone, and in other cases, they can be used with a relay harness to ensure smooth, uninterrupted power delivery.
Construction: GTR Lighting is known for producing high-quality HID and LED accessories, and these are no exception.
Their die-cast housings allow the internals to be fully potted and protected against the elements.
The integrated mounting point is a nice feature.
The braided mesh insulation protects the wiring, and the over-molded connections are highly corrosion-resistant.
Plug and Play: No complicated wiring is needed to resolve this common issue.
The GTR Ultra 2.0 Anti-Flickers are easy to set up.
With an input and output specifically sized to match your original wiring and the input of the bulb or ballast, these will simply plug and play in between.
Daytime Running Lights often operate off both pulsed voltage and low voltage.
It's important to know which one your car uses, as these will not resolve issues with a low voltage setup since they do not increase the voltage from the car; they only smooth it out.
