How to Put LED Lights on a Mirror

Installing LED lights on a mirror can be done by attaching a strip of LED lights onto the frame or glass surface of the mirror. The LED strip should ideally be placed on all four sides so the lighting will be perfectly balanced and all parts of your face and neck will be illuminated. If the mirror doesn’t have a frame, you can attach the LED strip light directly onto the surface of the mirror, creating a thin lighted frame. 

LED lights to need electricity to work, so you need to make sure there’s a suitable power outlet to connect the lights to. It’s important to follow the manufacturer’s instructions for attaching the LED light strip into a compatible power supply unit and connecting it to electrical power. 

This is the easiest and simplest method of putting LED lights on a mirror. We’ll go into the step-by-step process below.

Part 1: Preparing the Materials

Part 1 of this DIY lighted mirror project is the preparation stage. For this preliminary step, you’ll need to prepare and measure your mirror, acquire LED strip lights, and get a compatible power supply unit.

Preparing and Measuring the Mirror

The first step is to prepare and measure the mirror you want to put lights on. For this project, it would be easier to use a square or a rectangular mirror. If you have a framed mirror, it’s ideal to put the lights on the frame itself. 

Use a tape measure or a ruler to measure the top, sides, and bottom part of the mirror where you want the lights to go. If the mirror does not have a frame, make your measurements an inch from the edges. This way, the lights would serve as a border or a lighted frame. 

Take note of the measurement because this will give you an idea of the length of the LED strip light you’ll need. If you want the lights to be brighter, multiply this measurement by 2 and then add an allowance of about 4-6 inches in case you need to adjust the lights.

Getting LED Strip Lights

For this project, you will use LED strip lights, also called LED tape lights. LED strip lights come in a roll or a reel and have an adhesive backing that makes them easy to stick to a surface. 

Choose a warm white color temperature with a Color Rendering Index or CRI of at least 90. This is closest to daylight or natural light and would render colors accurately. Check to see if the length of the LED strip is enough for your project, based on the measurement of your mirror.

Getting the Power Supply Unit and Connectors

To connect the LED lights to electricity, you’ll need a power supply unit and LED strip connectors. The power unit looks like an adaptor for laptops and other electronic devices. It should be compatible with the voltage that the LED strip lights use. The LED lights connect to the power supply unit, which is then plugged into a power outlet near where the mirror would be placed. 

If you’re not sure about the type of power unit and other accessories you’ll need for your LED lights, you can get all of these as a bundle. Some manufacturers and distributors sell LED strips as part of a lighting kit complete with accessories. You can even choose to buy a dimmer along with the LED strip and power unit.

Part 2: Installing the LED Lights

This is the main part of the DIY lighted mirror project, and it’s where you attach the LED strip light to the mirror, connect it to a power source, and test it.

Attaching the LEDs

Once you have your mirror, the LED strip, and the power unit ready, you can start attaching the LED lights to the mirror. Cut the length of strip light you need based on the measurements you’ve made. Make sure you only cut along the designated cutting point as shown in the LED strip instructional manual which is included in the package. 

Next, wipe down the part of the mirror’s frame or glass where you will be putting the LED lights. It’s important to remove any dust or oils from the surface so that the lights will adhere better and stay put. 

After cleaning the mirror, peel off the adhesive backing from the LED strip and carefully stick the strip on the mirror’s frame or surface. LED strip lights are flexible so you can bend them around corners. Check out this video to see how it’s done.

Take time to make sure each part is taped down well. If there is any part that won’t stick to the surface, you can use thin double-sided tape to secure the strip on the mirror.

Connecting the Lights to the Power Supply Unit

After you finish sticking the LED strip onto the mirror, you need to connect it to the power supply unit. The method of setting up the strip light and connecting it to the power supply unit varies because this would depend on where you purchased these components and the design of the strip. 

You can find a ready-to-use LED strip with a DC receptacle at the end or come with solderless connectors so you can easily connect the strip to the power supply unit. Check the instruction manual included with the lighting kit so you can be guided accordingly.

Testing the Mirror Lights

Once the electronic components are all properly set up, it’s time to test the LED lights. Plug the power supply unit into an electrical outlet, preferably the one nearest to where you’ll be putting the mirror. 

If the LEDs around the mirror light up, it means you’ve connected them properly. If they’re not lighting up and you’re sure there’s nothing wrong with the electrical outlet, then you’ll need to go back and check the connections. Make sure you unplug the power unit first before checking and making the necessary fixes to the LED wiring.

Part 3: Mounting the Lighted Mirror

After checking to see if the LED lights work as they should, you can now hang your lighted mirror. But before you do that, make sure the mirror is clean and that the wall mount is secure so that the mirror stays in place. Follow these tips for proper mirror installation.

  • If the mirror has an existing wall mount, check it to see if it’s still in good condition. Some mounting hardware may wear out over time, so it’s better to be careful and replace rusty or loose components with new ones.
  • If you are installing your mirror in a new spot on the wall, make sure you use brackets and screws that would suit the type of wall you have. Consider hiring a handyman when needed.
  • Wipe the surface of the mirror clean before hanging the mirror. Take care when cleaning around the LED lights.
  • Make sure the power supply unit is placed in a safe, cool, and dry spot and that the plug doesn’t wiggle in the outlet. Use a cable tie to keep the wires in place, especially if the power cord is long.
  • Check the LED lights from time to time to see if the adhesive backing may need some reinforcement. It’s common for strip lights to sag or falls off, especially if the mirror is in a humid area. We recommend using a high-bond double-sided adhesive or mounting tape for parts of the LED strip that won’t stick.

You can have the option of adding the lights in front or at the back of the mirror. See to it that you decide how you will position the mirror.

You cannot put lights on the back of any mirror that will be attached closely to the wall. On the other hand, if you are using a portable tabletop mirror that will not go against the wall, there is no need to add lights behind it. Leave at least an inch or two of a distance between the wall and the mirror. This way, the light strips that are attached at the back of the mirror can create a stunning lighting effect.

Below are the additional steps that you need to take when adding LED light strips into a mirror:

Clean the Mirror

Carefully clean the surface of the mirror. It should be spotlessly clean regardless you attach the lights at the back or front. Any dust and debris on the mirror will make it harder for the adhesive from sticking properly.

Dry the Mirror

Use a paper towel to dry the surface of the mirror. Like dust and debris, any moisture that is left after cleaning the mirror will make it harder for the adhesive to stick on the surface of the mirror.

Glue the LED Lights

Once the mirror is clean and dried, you can glue the light strips on the surface. Most LED light strips come with their own 3M super glue at the back. In case there is none, you need to use super glue that works for glass and plastic.
