Most of the business owners overspend and conduct no research and find their signs fading or breaking after two years. Below is the list of the top 5 mistakes that are made repeatedly. 

This includes choosing poor LEDs, making wrong measurements, bypassing council approval, selecting wrong installer and treating signage as an expense and not as an investment.

I’m breaking down the truth about illuminated signage cost, the real math behind LED vs. traditional signs, and why “just get three quotes” is bad advice that pushes you toward the cheapest option, not the best one.

Quick Takeaways

• The cost of electricity for LED lighting is reduced by 60-80% in comparison to neon or fluorescent options.
• High-quality modules of LEDs withstand over 50,000 hours, which is almost five-six years of continuous operation.
• Outdoor signs in Melbourne require permission from councils in relation to size, brightness, and location; therefore, permission must be checked prior to purchasing.
• An optimally placed lighted sign can increase retail traffic by up to 24%, becoming a real source of sales.

Mistake #1: Looking Only at the Price Tag, Not the Full Cost

This is where people lose money. You see a cheap quote and think you’ve won. But that number tells you almost nothing about what you’re really buying.

LED signage is far cheaper to run than old-style fluorescent signs. The shift to LED brings energy savings of 60-80% compared to traditional lighting, along with cost savings of $95 to $300 or more per sign each year on electricity. 

So when a supplier’s quote is $400 cheaper, ask why. What grade LEDs are they using? Cheap now often means expensive later.

Mistake #2: Getting the Design Wrong Before the Sign Even Goes Up

Bad design is quiet. You won’t notice the problem on day one. You’ll notice it three months later, when foot traffic hasn’t moved.

I’ve seen shop signs fail not because of wiring but because someone picked a fancy font that nobody could read from the street. Here’s what to check before you approve any design:

Design Checklist: Fix These Before You Order

• Font looks nice but is hard to read at a glance
• Light text on a light background (basically invisible)
• Sign is too small for the building or the street
• Brightness turned up too high, creating glare instead of attention
• No clear order; logo, name, message all fighting for space
• Great sign, terrible spot (blocked by trees, poles, or shadows)
• Always go for bold, high-contrast lettering
• The size should match the viewing distance
• Choose colours that match your brand, every time

Here’s a contrarian take: everyone assumes brighter is always better. It isn’t. A sign that’s too bright for its surroundings creates glare and washes out your message rather than grabbing attention. Getting the brightness right for your specific location matters more than just cranking up the wattage.

Mistake #3: Skipping Council Rules Until It’s Too Late

Installation isn’t the fun part of buying a sign. But it’s the part that gets people fined or forced to redo everything.

And in Melbourne, this is real. Councils have specific rules about outdoor signs: size, placement, and how bright they’re allowed to be.

I’ve seen a business owner spend thousands having a sign taken down and repositioned, simply because nobody checked the permit first. That’s money wasted for no reason.

What Proper Installation Actually Looks Like

1. Site check first: angles, wall type, where cables run
2. Council approval confirmed: before you order anything
3. Licensed electrician on site: not a mate doing a favour
4. Weatherproofing verified: UV protection and sealed housing for outdoor use
5. Final safety check: wiring, mounting, everything signed off

Don’t skip step two. Ever.

Mistake #4: Picking a Supplier Based on Reviews Alone

Reviews tell you the sign looked good in a photo. That’s it. They don’t tell you the LED grade used, whether the frame is properly coated, or what happens when something breaks in month seven.

Ask These Questions Before You Sign Anything

• What LED module grade do you use, and can I see the spec sheet?
• Is the acrylic face UV-resistant? What’s the rated lifespan?
• Who handles council approval, you or me?
• What’s covered under warranty, and for how long?
• Do you offer after-sales support, or do I get a call centre?
• Can I visit a sign you’ve installed nearby?

That last one matters most. A supplier proud of their work will happily show you around. If they hesitate, that’s your answer.

Mistake #5: Thinking of Signage as a Cost, Not a Growth Tool

This mistake isn’t about doing something wrong. It’s about thinking too small.

Signage isn’t decoration. It’s one of the cheapest ways to bring in new customers. A study by Rise Vision found that retail stores can see up to a 24% increase in foot traffic by using digital displays. And about 80% of shoppers are influenced to enter a store after seeing digital signage.

It changes buying behaviour too. Digital signage can increase average purchase amount by 29.5%. That’s not a small bump. That’s a real shift in revenue.

But none of that matters if you picked the wrong sign, stuck it in the wrong spot, or hired a supplier who vanishes after installation.

Frequently Asked Questions

1: What mistakes should businesses avoid when buying illuminated signs? 

Overspending on the wrong upfront quote, ignoring design basics, skipping council approval, choosing a supplier without checking credentials, and treating signage as decoration instead of a sales tool.

2: What type of illuminated sign works best for retail? 

Signs using LEDs and high contrast letters that are also weatherproof. They’re brighter, more durable, and cheaper to operate than older models like neon and fluorescent.

3: Do I need council approval for an outdoor sign in Melbourne?

In most cases, yes. Rules vary by council area, so always confirm before you order, not after installation.

4: What should I ask before ordering a sign? 

Ask about LED grade, warranty terms, who handles council approval, and whether you can see a completed local installation first.

5: How do I choose a reliable signage company? 

Look for a company with its own manufacturing facility in Melbourne. Ask if they handle the permit process and what their warranty covers regarding labour and equipment.
