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.

Is backlit decal the same as a backlit overlay?
Asked 2 years ago by Signs

Backlit film and backlit overlays are often used interchangeably but take note that backlit overlays can sometimes be non-adhesive.

Will my backlit decal damage or ruin the surface I applied it to?
Asked 2 years ago by Signs

Our backlit decals are easy to peel off and will not leave any residue on the surface. There’s no need to use a sharp object to lift any corners.

Can my backlit decal be used outside?
Asked 2 years ago by Signs

Our backlit decals are designed for indoor and outdoor use. However, the material will not stick to porous and rough surfaces.

What are the typical uses of backlit decals?
Asked 2 years ago by Signs

Many businesses use backlit decals to advertise to passing traffic. Another very common use is as storefront signage to display store hours or to promote sales and promos.

Inside establishments and in darker locations such as subways and movie theaters, backlit decals are used as wayfinding signage.

Are backlit decals water-resistant?
Asked 2 years ago by Signs

Yes. However, constant exposure to water may impact the lifespan of your decal.

Will the backlit decal affect the transparency of my window or storefront?
Asked 2 years ago by Signs

The backlit decal is semi-translucent so the design can easily be seen against a light source. Note that if you plan to cover your entire storefront, the decal can block the view when it’s dark or when the lights are off.

Can I place my backlit decal on the inside of my storefront/window instead of sticking it outside?
Asked 2 years ago by Signs

Unlike our other decals, backlit decals can't be reverse-printed because the design can only be printed in front of the adhesive.

Can I remove my backlit sign and reposition it?
Asked 2 years ago by Signs

No. Removing the actual backlit film and trying to reposition it on the same light box or a different one altogether will not work. The backlit film is not intended to be reusable.

Of course if the film is applied to a rigid piece and you are moving both of them without removing the decal from the rigid material then it is possible. You simply will need to verify that the new light box or location will be compatible with the existing specifications of your rigid piece of material.

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

Installation of your backlit decal is easy. After ensuring that the surface where it will be applied has been cleaned and allowed to air dry, remove the thin backing protecting the adhesive side of the backlit sign.

Then, using a spray bottle with water mixed with a few drops of baby soap, liberally spray both the adhesive side of the decal and the surface you plan to apply it to. Thoroughly wetting your decal with water is key to a clean and smooth installation.

Carefully use a squeegee to squeeze out excess water and any air from behind the decal. Prior to using the squeegee, you should be able to peel it back up for any necessary repositioning.

Does installation require more than one person?
Asked 2 years ago by Signs

For larger decals, it’s best to ask for help so that you can install it properly. One person can focus on applying the sign and removing air bubbles, while the second person holds the sign to ensure that it doesn’t stick to the surface before it should.
