Lights system

[fairytail]

Hello. I have a code for left and right lights of the car, can someone explain me how do I make it both run on KEY_NUM8? Emergency (hazard) lights.

if(GetPlayerState(playerid) == 2)
        {
            if(IsACar(carid) && GetEngineStatus(carid))
            {
                if(PRESSED(KEY_NUM4))
                {
                    DestroyDynamicObject(LightsObject[carid][0]);
                    DestroyDynamicObject(LightsObject[carid][1]);
                    LightsObject[carid][0] = -1;
                    LightsObject[carid][1] = -1;
                    if(Signal[carid] == 1)
                    {
                        SignalTick[carid][0] = 0;
                        SignalTick[carid][1] = -1;
                        Signal[carid] = 0;
                        SetPlayerChatBubble(playerid, "включи левия мигач", COLOR_PURPLE, 30.0, 5000);
                    }
                    else
                    {
                        LightsObject[carid][0] = CreateDynamicObject(19294, 0, 0, 0, 0, 0, 0);
                        LightsObject[carid][1] = CreateDynamicObject(19294, 0, 0, 0, 0, 0, 0);

                        Signal[carid] = 1;
