Whether you are looking to cosplay a character or just to have glowing eyes for your next Halloween party, it’s not difficult to find a way to get the effect. However, if you want to do it yourself, you’ll need to learn a few things. You’ll need some basic supplies, as well as a little bit of knowledge about circuitry and LEDs.


What’s not to like about the DIY glowing eyeball masquerade? Not to mention the plethora of cosplayers that abound! Putting your brain to work for all hours of the day or night is the least of your worries! And while the aforementioned deeds may require some serious finesse, it doesn’t have to be. The aforementioned perks can be catered to your psyche and budget, not to mention the olfactory and the kin. With the right planning and a little chutzpah, you can be on your way to a snazzy soiree in the blink of an eye. To top off the experience, you’ll have a horde of sexy women to boot!

Materials you’ll need

If you are a true geek then you are probably already aware of the fact that the glowing LED eyes are all the rage. Getting one of these slick looking lights in your hair is a surefire way to turn heads at the next party. Thankfully, the process isn’t too hard to master. For a start, all you need is a few AA batteries and a roll of tape. After that, you are set.

Having said that, the actual task is not as fun as it sounds. The task of putting together a functional LED eye ain’t easy. To that end, it is important to keep a close eye on the project at all times. Even if the lights don’t come on, you can at least count yourself in the club. Of course, you will also need a few tools and parts to boot. Once you have that covered, you can get to the fun part. So if you’ve a spare afternoon on your hands and an open mind, get a few of the aforementioned AA batteries and some tape and you are set to rock.

A good guide is a must. Not only will you save time, you will also avoid getting nicked by some unscrupulous yoke aficionado.

Circuitry for the LEDs

In glowing eyes cosplay, the eyes are often lit with LEDs. These lights have high output, low heat, and short switching times. They are perfect for frequent on-off cycling.

For a long-lasting effect, you’ll need an adequate heat sink. LEDs are susceptible to burnout if the voltage is too high, if the power source is too strong, or if the package overheats.

LEDs have many applications. The first LEDs had a glass window, similar to that of an incandescent lamp, and were emitted through a lens. But more modern LEDs are produced in shapes and sizes.

When building LED circuitry, you can use simple resistors, but more complex systems have been developed. Some systems have been designed to include color- changing controls, blinking controls, and addressable controllers for RGB devices.

The Adafruit Gemma V2 microcontroller is one example. The microcontroller is powered by a 500mAh lipoly battery and sits in a 3D printed pocket. A vibration sensor is also needed.

Unlike fluorescent lamps, LEDs can be used without a microcontroller. However, you’ll need to use soldering to customize the lighting.

To get the best results, use small, high-efficiency LEDs. They can focus light better, and have a faster rise time. This gives drivers behind more time to react.

When designing your own circuitry, remember to insulate exposed wires. Overheating will damage sensitive fabrics and objects.

LEDs are relatively inexpensive to buy. You’ll need a few to light up a Halloween costume. Using LEDs can be a fun, quick project. It’s also a great way to add shine to your cosplay.

Battery for the LEDs is built into the helmet

You may have heard of helmet lights that have a battery built into the helmet. This is an advantage because it does not create a hot spot on your head and it does not make the light brighter than you need. It also allows you to add an external projection to your light.

While this type of light can be useful, it does have some drawbacks. First, it tends to be a bit heavier than a traditional helmet light. Second, it requires a wire connection, and this can be difficult to maintain. And third, it does not have the same power as a traditional helmet light.

If you’re looking for a helmet light with more power, you might want to consider purchasing one of the newer models on the market. For example, the FoxFury Command+ LoPro White & Green LED Helmet Light offers 100 lumens of panoramic lighting and features a high-visibility flashing red LED.

The Discover Tasker-Fire helmet light is another great option. This helmet light features a rear safety LED, two light intensities, and a high-powered CREE LED. In addition, it is made of aircraft-grade aluminum and comes with an AC power adaptor.

Some of the newer models are even USB rechargeable. This keeps the cost down while also reducing the number of batteries you need to purchase. They can run for several months on standard AA or AAA cells.

The Baja Designs S1 Pro LED is another helmet light that is powered by a rechargeable NiMH battery system. It comes with an adjustable bracket, magnetic bracket, zip ties, and a super-strong 3M mounting tape.

The Specialized Echelon helmet has a LED light module on it. Unfortunately, it lacks

the super bright LEDs that many other bike lights have. It also doesn’t have as much head coverage as other helmets. However, it has a good ventilation system and it is lightweight.
