If you're planning to mount your neon sign outside your business, hang it on your patio, or display it at an outdoor event, you’re probably wondering:
Can custom neon signs be used outdoors?
The short answer is: Yes — but only if they’re designed for outdoor use.
In this guide, we’ll explain how to know if your sign is outdoor-safe, what features to look for, and how to protect your investment.
🌧️ Not All Neon Signs Are Built for the Outdoors
Most neon signs sold online are built for indoor use only. If you expose an indoor sign to rain, humidity, or sun, you risk:
-
⚡ Short-circuiting the LED tubing
-
💥 Water damage to the power supply
-
☀️ Discoloration or fading from UV rays
Outdoor-rated neon signs, on the other hand, are built to withstand:
-
Rain and moisture (IP65+ waterproofing)
-
UV exposure and temperature swings
-
Dust, wind, and daily wear
🔍 Key Features of Outdoor Neon Signs
To safely install your custom neon sign outside, it should include:
-
✅ Waterproof LED tubing (rated IP65 or higher)
-
✅ UV-resistant acrylic backing
-
✅ Sealed power supply and wiring
-
✅ Durable mounting hardware
-
✅ Weather-rated power adapters or hardwiring
At Miami Neons, we offer both indoor and outdoor versions of every design — just choose “Outdoor” during checkout or request it in your quote.
📊 Indoor vs. Outdoor Neon Signs
| Feature | Indoor Neon Sign | Outdoor Neon Sign |
|---|---|---|
| Water resistance | No | Yes (IP65 rated) |
| UV protection | No | Yes |
| Mounting hardware | Light-duty | Heavy-duty secure mounts |
| Power supply | Basic adapter | Weatherproof or hardwired |
| Cost | Lower | Slightly higher |
⏱️ Can I Use an Indoor Neon Outside Temporarily?
We don’t recommend it. Even for a short event, moisture or wind can damage the sign or cause electrical failure.
If you must use it temporarily outdoors:
-
Keep it fully covered and dry
-
Avoid direct sunlight or wind exposure
-
Bring it inside immediately after use
