KueSync has two full-screen lights. Cue Lights follow the slides, with green NEXT on a forward press and red BACK on a back press. The GO Light follows Show Flow. It shows red STANDBY while the Show Caller stands by and green GO when the show goes. Both open on any screen, and neither can change anything in the show.

| For | The graphics op, a comfort monitor, a confidence screen | The stage manager, a crew position, a presenter’s monitor |
| Address | /kuelights on any fleet machine, port 37100 | /golight on any fleet machine, port 37100 |
The whole screen flashes, like a Perfect Cue light, in step with the fleet on every advance. When presses come fast, a small count (×2, ×3) shows how many there were. A Go to slide always flashes green NEXT, even when it jumps back. Between presses the screen is black, with a faint CUE LIGHTS, ARMED at the top. If it reads RECONNECTING, the screen is not live.
When an advancer makes a press it is not allowed to make, the screen shows dark red with a frame and BLOCKED. The slides did not move.
Open it from the KueSync menu (Mac) or tray (PC) with Open Cue Lights…, or on any machine in Settings › Displays › Cue Lights screen. Use Copy link for a phone or tablet on the show network. Move the mouse or tap the screen to show its Full screen button.

The same choice is on each advancer’s card in Settings › Show control › Advancers (Who is advancing?).
During the show
The GO Light is Show Flow’s standby light. It goes red STANDBY while the Show Caller’s Standby is on, green GO for a few seconds when Show Flow goes, and dark in between, with the next cue in small type. It works with Show Flow alone and needs no Companion and no QLab. If it loses the fleet, it turns grey and reads NO LINK.
For a Private show, a GO Light on a follower machine stays dark. Open it on the Leader, or use a link.
Open it in Settings › Displays › GO Light screen on any machine, or Copy link for a phone or tablet on the show network. Add ?names=0 to the address to show cue numbers only.
/kuesync/showflow/standby and /kuesync/showflow/next work the light through Show Flow, and /kuesync/golight/go flashes GO on its own. With Follow QLab armed and QLab GOs on the GO Light on, every GO in QLab flashes GO with its cue number (QLab and KueSync).With Internet access on, make a Cue Lights link or a GO Light link in Settings › Displays, under each screen. Give it a name, and add an email address to send it. The PIN is shown once. Later, Copy link on the link’s row copies the link again, and Copy PIN makes a new PIN (the old one stops working). Each link is separate. You can remove it at any time, and it cannot change anything in the show. For a Private show, a GO Light link shows STANDBY and GO with no cue numbers or names. More in Remote crew and screens.
| What you see | Fix |
|---|---|
| Cue Lights flash on the booth’s presses too | Tick only the presenter’s advancer in Drives fleet and internet Cue Lights. |
| Cue Lights stay black on KueSync Control’s NEXT | Another advancer is ticked in Drives fleet and internet Cue Lights and KueSync Control is not. Tick it too. |
| Cue Lights stay black on every press | Check the top of the screen. RECONNECTING means it has lost the fleet. Reload it, or open it again. |
| The GO Light never shows STANDBY | Standby comes from the Show Caller. Press STANDBY in KueSync Control, or send showflow/standby from Companion or QLab. |
| The GO Light shows numbers but no names | The address has ?names=0. |
| A GO Light shows STANDBY and GO but no cues | It is a link and the show is Private. |
| A GO Light on a follower stays dark | The show is Private. Open the GO Light on the Leader, or use a link. |
| A link does not open | Internet access is off, or the link was removed. Make a new one. |
| The Stream Deck lamp stays lit | The Companion connection is on Latch. Set Cue light mode to Flash. |
