DIY Disco Lights: How to Make Disco Lights at Home with Your Phone in 7 Steps
Short answer: You can make DIY disco lights with what you already have: phones, a light wall or ceiling and a Bluetooth speaker. Stick a Flashy, a small color filter, on each flashlight LED and aim the light at the ceiling and walls – never into anyone's eyes. Every phone becomes a colored spotlight. For lots of spots in every color, go for the Collectors Edition (21 Flashys in 7 colors); to get started, try Fairy Lights.
What do you need to make DIY disco lights?
A disco needs two things: music and colored light. You usually have both with you already. Your phone flashlight is a small, strong light source – add a color filter and it turns into party light.
Your shopping list is short:
- Phones: yours, your friends', or an old phone from the drawer
- Flashys: one Flashy per phone, stuck on the flashlight LED
- A Bluetooth speaker for the playlist
- A light wall or ceiling as the "screen" for the light
A Flashy is 7 mm small. No app for the color, no pairing. It fits all smartphones, iPhone and Android. With a large LED ring, you stick on several Flashys – every pack contains several filters.

How to make disco lights at home: the 7-step guide
1. Pick your room and clear it
Living room, shared kitchen or basement – all you need is room to dance and a light surface. Move trip hazards and cables out of the way. Ceiling light off, curtains closed.
2. Collect your light sources
Every phone is a spotlight. For a small room, two or three are often enough; for a bigger space, add more. Ideas for what else an old phone can do: Uses for Old Phones.
3. Choose a color scheme
Pick a mood:
- Neon look: Power Pink, Mystic Violet and Sky Breeze (turquoise) from Fairy Lights
- Warm & funky: Flame Red, Solar Orange and Royal Gold from Sunset Lights
- Full palette: all 7 colors from the Collectors Edition – three Flashys each of Flame Red, Solar Orange, Royal Gold, Power Pink, Mystic Violet, Sky Breeze and Emerald Green
- Surprise: Mystery Light with seven different Flashys – with a bit of luck, a rare Aurora Flashy is inside
4. Stick on the Flashys
- Clean the LED
- Peel the Flashy off the carrier card
- Stick it on the center of the LED
- Flashlight on
5. Set up your spots
- Ceiling spot: lay a phone flat on a shelf or on the floor in a corner, LED facing up. The ceiling fills with color.
- Wall spots: lean phones sideways against books and angle the light at the wall. Spread them across different corners and the room feels bigger.
- Color mix: let two patches of light overlap a little and see how the colors look together on your wall.
Important: every phone stays uncovered and in the open. Don't cover it, don't put it inside a container, and place it where it can't fall.
6. Sound on
Connect the Bluetooth speaker and start the playlist. Tip: one color per phase of the night – slower songs in Royal Gold, fast ones in Power Pink or Sky Breeze.
7. Color switch on the chorus (optional)
Switch colors on the chorus: first Power Pink, then Sky Breeze, then Royal Gold – everyone aims their phone at the wall or ceiling. Steady light, no flashing.
Safety: Never shine the light into anyone's eyes. Small parts (7 mm): adults stick the Flashys on and keep them out of reach of small children. You can reuse a Flashy a few times if you peel it off carefully and stick it onto a dust-free surface.
Which DIY disco setup fits you?
| Situation | Setup | Pack |
|---|---|---|
| Small room, spontaneous | 2–3 phones on ceiling and wall | Fairy Lights or Sunset Lights |
| House party, basement | Several spots, every color | Collectors Edition |
| Crew in one color | All phones the same | Friends Pack |
For a crew color: the Friends Pack (5 Flashys in one color) is enough for five. Colors: Flame Red, Royal Gold, Power Pink, Mystic Violet, Sky Breeze (turquoise), Ocean Blue (deep blue) and Emerald Green – no Solar Orange.
To be honest: for a big hall with lots of guests, a proper lighting rig is more reliable. For a living room, shared flat or basement, your DIY setup does the job.
