How to get the battery of the bike light

For getting battery status from lightNetwork, you cannot just use getBatteryStatus(null). Since there can be multiple lights, you have to use getBikeLights() first and iterate over the array and use the light identifier. Like this:

var bikeLights = myBikeLights.getBikeLights();
if (bikeLights != null) {
    for (var i = 0; i < bikeLights.size(); i++) {
        if((bikeLights[i] != null) && (bikeLights[i] instanceof AntPlus.BikeLight)) {
            var batteryStatus = myBikeLights.getBatteryStatus(bikeLights[i].identifier);
            if (batteryStatus != null) {
                Sys.println("Light status (" + bikeLights[i].identifier + "): " + batteryStatus.batteryStatus + ", " + batteryStatus.batteryVoltage);
            }
        }
    }
}

myBikeLights is instance of AntPlus.LightNetwork.

I'm trying to post my code but it keeps saying I'm blocked so i'll put it below (sorry for the mess). It;s not all my code, but you should the idea and be able to fill in the blanks regarding variables etc..

If you only have 1 light then you probably dont need to find the model numbers, but I have 2 ANT+ lights, and I wanted to seperate the battStatus for Headlight vs tailight. So I needed to find the Model number.

//Light Network and Battery Bar
        // LIGHT_NETWORK_STATE_* NOT_FORMED = 0, FORMING = 1, FORMED = 2
         // BATT_STATUS_NEW = 1, BATT_STATUS_GOOD = 2, BATT_STATUS_OK = 3, BATT_STATUS_LOW = 4, BATT_STATUS_CRITICAL = 5
        if (AntPlus has :LightNetwork){
            eLightlistener = new AntPlus.LightNetworkListener();
            eLight = new AntPlus.LightNetwork(eLightlistener);      
            eLightList = eLight.getBikeLights();
            eLightState = eLight.getNetworkState();    
            if (eLightState == 2 && eLightList != null) {
                 for (var i=0;i<eLightList.size();i++){
                    var eLightId = eLightList[i].identifier;                            
                    var eLightManu = eLight.getManufacturerInfo(eLightId);
                    var eLightProd = eLight.getProductInfo(eLightId);
                    var eLightBatt = eLight.getBatteryStatus(eLightId);
                        if (eLightBatt != null){
//                            Sys.println("Light_ " + "State:"+ eLightState +" Man#:"+ eLightManu.manufacturerId +" Model:"+ eLightManu.modelNumber +" HW Rev:"+eLightManu.hwRevision+" Serial:"+eLightProd.serial+" Batt:"+eLightBatt.batteryStatus); //Use to identify Model# that referes to Front or Rear Light
                            if (eLightManu.modelNumber == 1){
                                eTailLightBatt = eLightBatt.batteryStatus;                                    
//                                Sys.println("TailLight:"+eTailLightBatt);                                    
                            }
                            else if (eLightManu.modelNumber == 4){
                                eFrontLightBatt = eLightBatt.batteryStatus;
//                                Sys.println("FrontLight:"+eFrontLightBatt);
                            }
                        }
                }    
            }
        }
