LED Open Sign
— Bright, Custom-Sized Open Signs for Storefronts & Businesses
An LED open sign that tells customers you are trading — the word OPEN in a bright, custom-sized panel, built on 8 mm acrylic with a CNC-carved groove, SMD 2835 LED and a silicone diffuser. Plug-in, battery or hardwire, standard or daylight-bright output, in any size from counter to storefront, with MOQ 1 and 3–7 day production.
What Is an LED Open Sign?
An LED open sign is a ready-made or custom-sized illuminated sign that shows the word OPEN — sometimes with trading hours, an open/closed toggle, or your logo. It sits in a window or above a door and does one job: tell passers-by the business is trading. Built on the same 8 mm acrylic, CNC-carved groove, SMD 2835 LED and silicone diffuser as our custom neon signs, it is bright, robust and cheap to run, and it is made to order so the size and colour fit your space.
Types of LED Open Signs

- OPEN text only — the classic single word at maximum visibility.
- OPEN + hours — a trading-hours line under the word, for shops with set hours.
- Open / Closed — a two-state sign that toggles or flips, for split-day trading.
- Logo + OPEN — your brand mark and the word on one panel.
Power Options: Plug-in, Battery or Hardwire

The plug-in version ships with an AC adapter and is left on for the day. The battery version needs no outlet, so it suits a counter or a window far from a socket. The hardwire version connects permanently to mains for a clean, professional install. All three use the same low-voltage LED module — only the power source changes.
| Power option | Best for | Note |
|---|---|---|
| Plug-in adapter | Window, counter near an outlet | AC adapter included |
| Battery | Counter, no outlet nearby | Portable, rechargeable |
| Hardwire | Permanent above-the-door install | Direct to mains |

Brightness & Visibility

An open sign is useless if it cannot be seen, so output is matched to where it sits: a standard strip for an interior counter, a high-output strip that reads through a sunlit window, and a dimmable option that runs bright by day and softens at night. The silicone diffuser evens the glow so the word is uniform, not spotty.
Size Options

Size the word to the viewing distance. A counter sign is 8–14 inches; a window sign 14–24 inches; a storefront sign above the door is 24–48 inches or more. Because the panel is custom-routed, you are not limited to off-the-shelf sizes.
| Placement | Typical size | Viewing distance |
|---|---|---|
| Counter | 8–14 in | 3–6 ft |
| Window | 14–24 in | 6–15 ft |
| Storefront / above door | 24–48 in | 15–40 ft |
Mounting Options

Fix the sign to the surface with a window mount that avoids drilling the glass, a wall standoff for a flush install, or a hanging cable in a deep window. A countertop version stands free and can be moved. Fixings and a drill template ship with every sign.
Colour Options

Warm white is the inviting default, cool white reads clean and bright, red and blue pull maximum attention, and an RGB module lets you set any colour or change it by day, season or promotion from an app.
Indoor vs Outdoor
The indoor version is IP44 and fine for a window or counter. The outdoor version is sealed to IP65 with gasketed cable entries and sealed joins, so it survives rain and the drafts at a doorway. Both use the same acrylic panel and silicone-diffused LED.
Failure Modes & Prevention
| Failure mode | Cause | Prevention |
|---|---|---|
| Not visible in daylight | Low-output strip | High-output SMD 2835 option |
| Battery runs flat | Undersized battery | Sized battery, rechargeable |
| Water ingress (outdoor) | Failed seal | IP65 silicone seal, gasketed entry |
| Driver failure | Undersized / overheating | UL-listed driver with headroom |
| Flicker on camera | Non-flicker-free driver | Flicker-free constant-voltage driver |
Certification & Compliance
Signs are built with CE- and RoHS-compliant components and UL-listed power supplies. Electric signs fall under UL 48; the RoHS Directive restricts hazardous substances, and the CE marking declares conformity for the EU market.
MOQ, Lead Time & Pricing
An open sign is made to order, so the minimum order is 1 piece — one sign for one shop, or a batch for a franchise of convenience stores, both run on the same line. Pricing is driven by size, colour tier and power option.
| Quantity | Pricing | Typical lead time |
|---|---|---|
| 1 piece | Single-unit price | 3–7 days |
| 5–100 sets | Tiered | 7–14 days |
| 100+ sets | Wholesale / OEM | 14–30 days |
Production & Packaging
Each sign is CNC-routed from your approved layout, assembled, tested through a 24-hour burn-in and a luminance check, then packed in a rigid carton (plywood crate for export). A digital proof is confirmed before production.
The Buying Process
- Choose your layout — OPEN, OPEN + hours, open/closed, or logo + OPEN.
- Choose power, size and colour — plug-in, battery or hardwire.
- Approve the proof — a digital proof for sign-off.
- Production and delivery — CNC routing, testing, then crated and shipped.
Supplier Evaluation Checklist
- Is the sign custom-sized, not limited to stock dimensions?
- Can you choose power (plug-in, battery, hardwire) and colour?
- Is there a high-output / daylight option for the window?
- Is it CE / RoHS / UL compliant with a Class 2 output?
- Are MOQ, lead time and warranty written in the quote?
Frequently Asked Questions
Is an LED open sign visible in daylight?
Yes. We offer a high-output SMD 2835 strip for window and storefront signs so the word OPEN reads in full sun, with a dimmable option to soften it at night.
Can the open sign run on battery?
Yes. A rechargeable battery version is available for counters and windows far from an outlet, alongside the plug-in adapter and hardwire options.
Can I add my logo or trading hours?
Yes. The sign can show OPEN with a trading-hours line, an open/closed two-state toggle, or your logo plus the word on one panel.
What size open sign do I need?
Match the word to the viewing distance: 8-14 in for a counter, 14-24 in for a window, and 24-48 in or more for a storefront above the door.
What is the MOQ and lead time?
The minimum order is 1 piece. Production is 3-7 days for one piece, 7-14 days for 5-100 sets, and 14-30 days for 100+ sets.
Is the open sign weatherproof?
The indoor version is IP44; the outdoor version is sealed to IP65 with gasketed cable entries and sealed joins for rain and doorway drafts.
