Timer restart - but only for these timers already running

Setup, Configuration and Use Scripts & Rules

Pi4b, OH2.5.12

In the rule below I switch multiple items and start a timer per item when the state =! ON
So I am able to “not” switch items which might be activated manually before and should stay untouched.

When now another trigger switches during the timers are running I would like to restart exactly the running timers only.
How can I do that?

var Timer LED_Nachbar_Timer = null
var Timer LED_GVorne_Timer = null
var Timer LED_GWald_Timer = null

rule "Einfahrt_Licht"
when
        Item DW2_TOR received update ON or
        Item S_Touch90_1 received update ON or
        Item zwave_device_6c898019_node8_scene_number received update 4
then
        if(Nacht.state != OFF) {
                if(LED_Nachbar.state != ON) {
                LED_Nachbar.sendCommand(ON)
                LED_Nachbar_Timer = createTimer(now.plusSeconds(240), [|
                LED_Nachbar.sendCommand(OFF)
                ])
                }
                if(LED_GVorne.state != ON) {
                LED_GVorne.sendCommand(ON)
                LED_GVorne_Timer = createTimer(now.plusSeconds(240), [|
                LED_GVorne.sendCommand(OFF)
                ])
                }
                if(LED_GWald.state != ON) {
                LED_GWald.sendCommand(ON)
                LED_GWald_Timer = createTimer(now.plusSeconds(240), [|
                LED_GWald.sendCommand(OFF)
                ])
                }
        }
end

Issue is solved
Udo helped me here to get it solved.

The trick is to add two lines per if statement.
Each timer will be reschuled independent on the LEDs ON or OFF, exactly what I am searching for

Example:

    if(Nacht.state != OFF) {
        if(LED_Nachbar_Timer !== null)
            LED_Nachbar_Timer.reschedule(now.plusSeconds(240))
        if(LED_Nachbar.state != ON) {
            LED_Nachbar.sendCommand(ON)
            LED_Nachbar_Timer = createTimer(now.plusSeconds(240), [|
                LED_Nachbar.sendCommand(OFF)
                LED_Nachbar_Timer = null
            ])
        }
