What Are Backlit Decals?

Make your sign shine day or night with a custom backlit decal (light box not included). Made from 3.5 mil adhesive vinyl, backlit decals are designed to withstand exposure to heat from light sources as well as indoor and outdoor elements. Because of the flexible property of the backlit decal, you can easily apply them to windows, light box sign panels or other smooth translucent surfaces for a fantastic light up effect.

Easy to install on acrylic, glass or molded resin, you’ll get a great looking sign that will last as long as you need. If you need to switch out a backlit decal for another, removal is easy. Printed using the best printing technology using UV inks, your backlit sign will display beautifully both day and night.

Simple Installation with No Professional Help Required

The following installation instructions will help you with a quick and easy installation of your custom backlit decal. Instructions will also be included with your order, and you are free to refer to this page or download a PDF of the instructions for assistance. If you are installing a large decal we recommend having at least one other person assist you.

Step 1 for Installing Custom Backlit Decals

Before you begin to install your custom backlit decal, we recommend gathering the following supplies to help with the process:

  • Spray Bottle
  • Paper Towels
  • Application Squeegee (available for purchase with order)
  • Window Squeegee
Step 2 for Installing Custom Backlit Decals

Begin by thoroughly cleaning the light box panel, acrylic or glass surface you intend to use for your backlit decal—any household window cleaner will work. After cleaning, use a window squeegee to remove excess water or allow appropriate time for the window to air dry.

Step 3 for Installing Custom Backlit Decals

Create a decal application solution by combining 3 drops of dish soap or detergent (not hand soap) per 1 gallon of water and place into a spray bottle.

Step 4 for Installing Custom Backlit Decals

Lay your backlit decal face down on a flat, smooth surface and carefully begin to remove the back liner.

Step 5 for Installing Custom Backlit Decals

As you are removing the backing, generously apply the application solution to the back of the decal. Next, spray a generous amount of application solution to the desired surface, making sure both the adhesive side of the decal and the panel surface are now sufficiently wet. Do not submerge the decal into water in an attempt to soak the adhesive side.

Step 6 for Installing Custom Backlit Decals

You can now apply your backlit decal to the desired window or glass surface. The application solution will allow the decal to slip and move once it is on the light box panel or window. Use this to your advantage by sliding the decal into the final position you would like it to be.

Step 7 for Installing Custom Backlit Decals

Once the backlit decal is in its final position, place the removed backing over the face of your decal and use the application squeegee to remove air bubbles/application solution from under the decal. When doing so, start in the center of the decal and press firmly to the right or left edge. Continue this process until you have ran the squeegee over the entire surface of the backlit decal.

Step 8 for Installing Custom Backlit Decals

Use paper towels to clean the edges of the backlit decal and around the light box or window. This will help remove excess water from the edges of the decal. It may take several days for the adhesive to fully dry and bind to the panel or backlit surface.

To increase the longevity of your backlit vinyl decals, we recommend regularly cleaning them with a damp, non-abrasive cloth or rag. Gently wipe the decal down to remove dirt and dust. Do not power wash the decal, as doing so may cause it to tear or dislodge from the surface of the sign. Power washing might also ruin the light source behind the backlit panel. If you need to remove or replace your backlit decal, simply peel it away from the surface. In some cases, a sharp edge or heat source such as a blow dryer may be needed. After removing the decal, clean the surface with any standard window cleaner.

How do I store my backlit decal?
Asked 2 years ago by Signs

Prior to installation, your backlit decal can be either rolled or stored flat in a cool, dry location. If rolled during storage, nothing heavy should be placed on top of the decal to avoid creasing.

How do I clean my backlit decal?
Asked 2 years ago by Signs

Wipe your backlit decal regularly with a damp, non-abrasive cloth to remove built-up dirt and grime.

How do I remove my backlit decal properly?
Asked 2 years ago by Signs

Our backlit decals are generally easy to peel off. For decals that have been around for a while, you may need to apply heat using a blow dryer to soften the adhesive. Wipe off any residue with a damp rag.

Can I wash my window with the backlit decal still installed?
Asked 2 years ago by Signs

Regular cleaning will help your backlit decal stay vibrant while it is in place but avoid power washers since the force can wash off the adhesive.

I’d like to design a custom decal for utility box. It’s located outdoors in LA. Things I’m interested in solar decals that light up at night, but are still vibrant during the day. And outdoor decals that will have some staying power but not permanent.
Asked 2 months ago by Gaby

Backlit decals are the perfect option for these. They are removable and have enough strength to stay up when installed outside. This can also be vibrant during the day. The vibrancy of the design would depend on the actual design itself.

What type of substrate do I need to buy for your sign to be applied to? I have a can with no reusable panels.
Asked 4 months ago by steve

We print the backlit decals on semi-translucent vinyl that adheres to light boxes, storefront windows, and other smooth, translucent surfaces.

Are you able to cut out portions of the decal or leave part of the decal fully transparent?
Asked 9 months ago by Kevin S.

Leaving some of the areas transparent won't be possible for backlit decals. I would suggest checking our clear window clings cause they would have an option to make some areas clear.
