The turn of the century brought with it fantastic home appliances that have made home life easy. One of these appliances is LED faucet lights. These light up when water passes through the faucet providing illumination below and, in some cases, a beautiful sight.

However, we have a vital question, how do LED faucet lights work?

How Do Led Faucet Lights Work?

LED faucet lights work in two significant ways: the use of a battery or hydropower. Despite the differences, they mostly share some lights having more than one color. The light’s colors might also coincide with the temperature of the water, with red signifying hot water and blue meaning cold water.

Battery-Powered Faucet Lights

Older brands of faucet lights use batteries as a power source. The batteries usually come in alkaline or coin cell form. However, you would find it difficult to find such faucet lights as hydro-powered lights have replaced them.

Hydro-Powered Faucet Lights

These lights are now the norm in the faucet light industry. A hydro-powered faucet light generates its power through a motor, much the same as a wind turbine. The motor creates friction when water passes through the motor and rotates it.

Friction is then used to generate the power needed to power the faucet light.

Why You May Need a Faucet Light?

Now that we understand the mechanics of how a faucet light works, it is time for us to discuss the reasons why you may need a faucet light. Below, we will highlight the most compelling reasons why you, as a homeowner, may need to have these lights at your home.

Aesthetic Value

Part of the human experience involves searching out beautiful and appealing material. What we find attractive tends to reflect our character and what we hold most valuable. We may then decide to make these aesthetically appealing parts part of us.

So why not spruce up your kitchen by purchasing a faucet light?

We typically use warm to hot water in the morning and night, with the inverse happening in the afternoons. However, it becomes difficult to tell the difference in water temperature levels just by guessing or looking. The situation may escalate to dangerous levels as hot water is known to cause scalds in both adults and children.

You need not worry because some LED faucet lights come in different colors. The different colors correspond to the water temperature: red to mean hot and blue to represent cold. Some other colors can indicate an intermediary water temperature level.

How to Dismantle an Led Faucet Light

Your LED faucet light has a projected lifespan of about ten years or over 80,000 usage hours. However, your LED faucet light might misbehave. Such malfunctions might be caused by:

  • Physical damage to the faucet.
  • Circuit malfunctions caused by cracks in the covering.
  • The faucet light’s turbines not getting enough pressure.
  • General Failure.

In some cases, if you are a tinkerer, you may want to open up your faucet light. Though it is not advisable, it is not a difficult task to do. You may only need to remove the nozzle, which you accomplish by turning it counter-clockwise.

Should the nozzle be stuck, you should try using pliers to turn it at a quarter turn.

You should be careful as the faucet lights, usually made of plastic, tend to be fragile. One wrong move and you may end up with broken light components that are impossible to put back together. We advise you to reach out to any trusted plumber or technician when you need your lights fixed.

Faucet Light Troubleshoot

This section aims to educate you on troubleshooting some fundamental problems that you may encounter with your light. These steps should not be exchanged for professional opinions but are more helpful in these situations.

When the Hydro-Powered Faucet Light Does Not Work

  • Water pressure. Low water pressure levels prevent the faucet light’s motor from turning; hence power is not generated. A clogged aerator or a defective sink cartridge might be the problem. In this case, you simply need to unclog the aerator or replace the sink cartridge.
  • Electric motor chip. The electric motor chip controls the functioning of the faucet light’s motor. A damaged motor chip prevents the motor from turning hence no production of power. Replacing the chip or the nozzle should fully repair the light’s functionality.

When the Battery-Powered Faucet Light Does Not Work

  • Battery direction. Batteries placed in the wrong direction prevent the lights from getting the necessary electricity. Placing them correctly, per the label, should restore functionality.
  • Circuit. A broken circuit does not provide the necessary instructions needed for the proper functioning of the light. You replacing the whole faucet light would be advisable.

There is a particular case whereby the battery-powered faucet light still functions even when the faucet is closed. This situation means that the faucet light will not turn off. Build up of minerals from the water in the faucet that causes contamination might damage the batteries or cables.

You can remedy this contamination by removing the aerator and regularly cleaning the faucet thoroughly.


A faucet light helps you out in various ways around the house. From providing illumination to gauging the temperature of the water, an LED faucet light offers a plethora of advantages that you may discover as you use it. We have also informed you of ways to care for and troubleshoot your faucet light to provide you with an altogether seamless faucet light usage.
