Double-Sided Neon Signs: A Guide for Storefront Buyers

Double-sided neon signs can help a storefront get noticed by people approaching from either direction. But a sign that looks good in a rendering still needs the right face construction, mounting system and electrical setup to work at your location. Buying two illuminated faces is only part of the decision.

For a shop, restaurant or bar, the first question is whether you need visibility along the sidewalk, through a window or across an interior space. Each calls for a different installation. This guide focuses on custom LED neon and explains what to settle before approving artwork, comparing quotes or requesting a rush order.

How double-sided neon signs work

A true double-sided sign presents an intentional, readable display on each side. That is different from a single LED neon design mounted on clear acrylic, where the lettering may be visible backward from behind.

The two faces can show the same business name, different messages or artwork adapted for opposite viewing directions. Depending on the design, the assembly may use separate back-to-back panels, a central housing or another construction that keeps the faces visually distinct.

Configuration	What viewers see	Buyer consideration
Single face on transparent backing	Correct lettering from the front, potentially reversed lettering from behind	Visibility through the backing does not make it a readable two-sided sign
Two faces mounted back-to-back	A readable design on each side	Confirm spacing, light separation and how both faces attach
Integrated two-sided housing	Two faces within one assembled structure	Confirm total depth, weight, mounting details and service access

Ask for a front view, rear view and side view before approving the design. A front-only mockup cannot show whether the opposite face reads correctly or how far the finished assembly projects.

Also confirm the lighting technology. Traditional glass neon and LED neon require different construction and servicing, so quotes should identify which one is being supplied.

Choose the viewing direction before the artwork

Along the sidewalk: consider a projecting sign

A sign mounted perpendicular to the building can face pedestrians approaching from opposite directions. This is often called a blade or projecting sign, although not every blade sign uses neon.

Before choosing double-sided neon signs for this position, photograph both approaches to your entrance. Look for trees, awnings, neighboring signs and parked vehicles that could hide the display. A larger face will not solve an obstructed sightline.

Walk the route at the hours your customers visit. Daylight, street lighting and nearby illuminated signs can change how noticeable the lettering is.

At the window: identify the two audiences

A two-sided window installation may address people outside and customers inside. Those audiences do not necessarily need the same message. The street-facing side might show your business name, while the interior side carries a short brand phrase.

Confirm whether the sign will sit parallel or perpendicular to the glass. Parallel placement can serve indoor and outdoor viewers, but it may do little for pedestrians approaching along the building. Reflections and objects behind the sign can also affect visibility.

For either position, approve the message from the actual approach angle rather than relying only on a straight-on rendering.

Specify the complete assembly, not just two faces

Face separation and readable artwork

With double-sided neon signs, light and lettering from one face can interfere with the other if the construction does not separate them adequately. Ask how the proposed design prevents distracting overlap, visible wiring or reversed lettering from showing through.

An opaque divider may be appropriate, but it is not the only possible solution. The fabricator should explain the construction chosen for your artwork and installation.

Keep each face focused on information someone can recognize while moving. A short business name or recognizable symbol is usually easier to interpret than a logo surrounded by a tagline, phone number and social handle.

Directional arrows deserve separate approval. Copying the same layout onto the opposite face can point customers the wrong way. Check each face from the position of the person who will read it.

Outdoor protection and accessible power

For exterior installations, request specifications for the complete installed system, including the LED lighting, wiring connections, power supply and any controller. A weather-resistant lighting component does not establish that every part of the sign is suitable for outdoor use.

Ask where the power supply will be located, how cables enter the assembly and whether the mounting orientation affects the manufacturer's installation requirements. A sheltered doorway can still expose a sign to wind-driven rain, condensation or cleaning water.

Our guide to buying an outdoor neon sign explains the broader environmental checks. For a two-sided build, also confirm that both faces and the space between them are covered by the proposed outdoor specification.

Battery power can be useful for temporary displays where a suitable system is available. For a permanent storefront, evaluate operating hours, charging access and maintenance before choosing it over a fixed power connection.

Check mounting, permits and electrical requirements

A projecting sign creates a different mounting problem from a lightweight panel attached flat against a wall. Wind acts on the sign's surface, while the distance from the wall creates leverage on the bracket and anchors.

Before ordering double-sided neon signs, give your installer the assembled dimensions and weight, not just the dimensions of one illuminated face. The installer also needs to know the wall construction. Brick veneer, structural masonry, wood framing and metal cladding require different attachment decisions.

Have the proposed installation reviewed for:

• Projection and clearance: The distance from the building to the sign's outer edge, clearance above the sidewalk and separation from doors or neighboring features.
• Structural attachment: Bracket design, suitable anchors and any engineering required for the location.
• Property approval: Landlord consent, lease restrictions and shopping-center or historic-district rules.
• Permits and electrical work: Applicable sign approvals, power connection requirements and inspection responsibilities.

In the U.S., the National Electrical Code addresses electric signs in Article 600. Your local authority determines the applicable adopted code and project requirements. Ask whether the finished assembly needs a particular listing, labeling or field evaluation, rather than assuming that listed individual components settle the question.

A qualified installer or electrician should confirm the power arrangement and service access. Do not plan around a permanent extension-cord workaround or leave the power supply inaccessible behind a sealed assembly.

Compare quotes on the assembled installation

The useful comparison is not simply the price per face. Two quotes can describe similar-looking artwork while including very different mounting hardware, environmental protection or installation responsibilities.

For double-sided neon signs, request an itemized scope that separates the illuminated assembly from brackets, electrical equipment, delivery and on-site work. Confirm whether the quote covers a complete two-face unit or two panels that someone else must assemble.

Quote item	What to establish
Artwork and fabrication	Both faces, finished dimensions, lighting technology and approved colors
Housing and mounting	Included brackets, attachment points, finish and responsibility for wall anchors
Electrical equipment	Power supplies, controllers, cable lengths and connection method
Installation	Who handles lifting, attachment, electrical work and inspections
Delivery	Packaging, destination, shipping service and damage-reporting procedure
After-sales support	Coverage, exclusions, replacement process and access needed for repairs

Avoid applying a supplier's advertised starting price for a small single-face sign to a custom projecting assembly. The second face, supporting structure and site requirements can change the scope substantially.

Ask how repairs would work after installation, too. Our commercial neon sign warranty guide covers questions about components, labor and shipping that are worth resolving before purchase.

Plan a rush order without skipping approvals

Rush fabrication is only one part of meeting an opening date. Artwork approval, property permission, permits, shipping and installer availability all affect when the sign can actually be switched on.

When requesting double-sided neon signs on a tight schedule, provide the required installed-and-operating date, not only a preferred delivery date. Ask the supplier to distinguish production time from transit time and identify what starts the production clock.

A useful quote request includes the business address, installation photos, approximate dimensions, artwork for both faces and intended daily operating hours. Add the proposed mounting position, indoor or outdoor exposure and any information your installer has already provided about power and attachment.

For the schedule, establish four milestones: artwork approval, production completion, delivery and installation. Ask whether the proposed shipping service is guaranteed or estimated and what happens if approval changes after fabrication begins.

Best Buy Neon Signs designs and builds completely custom LED neon signs at its factory in South El Monte, California. Rush production and shipping options are available for deadline-driven projects. Confirm availability for the proposed two-sided construction and destination before committing to an opening announcement.

Free nationwide delivery is part of the company's offer, but ask whether an expedited shipping request changes the delivery charge. Domestic production does not remove the need to allow time for transit, permits or installation.

Frequently asked questions

Can a regular LED neon sign be viewed from both sides? Some light may be visible through a clear backing, but text will generally read backward from behind. A true two-sided display needs artwork and construction intended for each viewing direction.

Can each side display a different message? A custom build can be designed around different messages, subject to the proposed construction. Request separate proofs for both faces and confirm that neither design shows through or interferes with the other.

Are double-sided neon signs suitable for outdoor use? They can be when the complete assembly is specified for the location and installed accordingly. Confirm the environmental suitability of the lighting, housing, connections and electrical equipment rather than relying on a general “outdoor” description.

Does the sign manufacturer handle permits and installation? Not necessarily. Ask who prepares any required drawings, obtains approvals, supplies mounting hardware and performs on-site work. These responsibilities should be written into the quote instead of assumed.

Should both faces share one power supply? That depends on the electrical design and equipment capacity. Ask the fabricator to specify the arrangement and explain how a failed component would be accessed or replaced.

Request a quote built around your storefront

Send Best Buy Neon Signs photos of your storefront, artwork for both faces and your required opening date to discuss a completely custom, U.S.-made LED neon project. Ask the quote to confirm two-sided construction, mounting responsibilities, environmental suitability and available rush options.
