Do You Need a Dual Beam Bulb Inside A Projector?

Here's why a dual-beam bulb isn't necessary if you have a projector headlight. Projectors can be classified as bi-xenon, bi-halogen, or bi-LED. These all rely on a single source of light. This cutoff shield is the cause of that recognizable line that appears where there is light and then none at all. It does this by preventing glare or anything else from blinding approaching drivers when the low lights are on, and this cutoff shield is up.

After that, your car will supply this actuator with power. This actuator controls the cutoff shield. When this actuator is powered on, the cutoff shield lowers, exposing the entire high beam. When you switch off the high beams, the cutoff shield immediately rises again.

The procedure remains the same whether you are using a bi-xenon or a bi-halogen projector. The source of the lights is the only distinction. An HID bulb will be used for bi-xenon. An example of a bi-halogen bulb is a standard halogen bulb. In any case, it is not a dual filament bulb; instead, it is a single filament halogen.

Not much has changed regarding that bi-LED projector. The primary distinction is the absence of a detachable lightbulb. Allow me to demonstrate the operation of the bi-LED projector. It is nearly identical to the bi-halogen and bi-xenon. This is where the LED chipset is located. In the same manner as previously, those LEDs will radiate light from the projector's chrome interior.

In reality, the low and high beams will be determined by the cutoff shield. You get that nice, clear cutoff line because there is no power coming to this actuator, and the cutoff shield is up. The cutoff shield will descend as soon as this actuator is powered on, engaging the entire high beam. There is no change in the power supply. You won't receive extra LED chips, more power, or anything like. But, you're becoming lighter.
