Lighting is one of the most overlooked parts of an arcade cabinet, right up until it’s the reason a machine looks either dead on the floor or absolutely commands attention from across the room. A few distinct lighting systems are worth understanding, whether you’re restoring an original or building something new.
The Marquee
That backlit header at the top of an upright cabinet — showing the game’s logo and artwork through a translucent panel — is traditionally lit by a fluorescent tube sitting behind it, powered by a small ballast. This is also one of the most common points of age-related failure: ballasts flicker, hum, or die outright after decades of service, and old fluorescent tubes dim well before they fully fail, leaving a marquee that looks washed-out rather than vibrant. Replacing an original fluorescent setup with an LED marquee light strip is now standard practice in the restoration community — LED kits run cooler, last dramatically longer, and eliminate the mild fire risk that comes with an aging ballast that’s been running continuously in an enclosed wooden cabinet for forty years.
Illuminated Controls
Modern builds, especially MAME and bartop cabinets, frequently use illuminated buttons — typically 5V or 12V LED buttons — to highlight player-start buttons or add visual feedback tied to gameplay. Wiring these correctly means checking whether your chosen buttons need an inline resistor to avoid burning out the LED, and whether you’re running enough amperage on that supply rail to handle a full panel of illuminated buttons wired in parallel without dimming or overloading the circuit.
Cabinet Accent Lighting
RGB LED strips run along the underside or interior edges of a cabinet have become a popular addition on custom and MAME builds, adding ambient glow without altering the original artwork or structure. It’s a purely aesthetic addition, but a well-placed strip along the kickplate or kneepanel can genuinely transform how a cabinet reads in a dim room, which matters more than people expect for a piece of furniture that’s meant to be a visual centerpiece.
The Coin Door Light
A small often-overlooked detail: many original cabinets included a small bulb inside or near the coin door, illuminating the coin slot for visibility in dim arcade environments. It’s a minor restoration touch, but replacing a dead coin door bulb is exactly the kind of small detail that separates a machine that’s been genuinely restored from one that’s just been repainted.
Practical Tips
- Always check local wiring gauge and fuse ratings before adding new lighting circuits to an old cabinet — don’t just tap into an existing line without confirming it can handle the added load.
- LED retrofits for marquees are widely available as drop-in kits sized to standard marquee dimensions, making this one of the easiest high-impact upgrades in the entire hobby.
- Test any new lighting circuit independently before final assembly — it’s much easier to troubleshoot a wiring issue with the cabinet open than after everything is buttoned up.
Good lighting won’t fix a mediocre restoration, but bad or dead lighting will absolutely undercut a great one — it’s one of the cheapest, most visible upgrades available, and there’s rarely a good reason to skip it.
