Help with signal and brake lights

If you use only beacon or normal lights, you can make it with AG's, three AG's in your case (indicators left, indicators right, break lights).
Then set every light to his specifical group.
For this example, i use AG 5, 6 (indicators L/R) and 7 (break).

Go to "edit program" then:

On start
While true
If input Jaw > 0 = true then
Set Activation Group 5 to true
Else
Set Activation Group 5 to false
If input Jaw < 0 = true then
Set Activation Group 6 to true
Else
Set Activation Group 6 to false
If input Brake = true then
Set Activation Group 7 to true
Else
Set Activation Group 7 to false

That won't work if you use glowing fuselage parts (XML edited), there you must rename every part (for exple LI1, LI2 (for left indicator 1 and so on)) and activate every part separately in vizzy.

@ChalxAerospace thank you

i posted a craft that might help, click here

you can use the program in your craft, but make sure you reorganize the activation groups (if there is any between AG1 - AG4)
