if(GetPlayerState(playerid) != 2) return SendClientMessage(playerid, COLOR_RED, "[ERROR] You cannot use this command while you are not the driver of a vehicle!");

if(lights != 1) SetVehicleParamsEx(GetPlayerVehicleID(playerid), engine, 1, alarm, doors, bonnet, boot, objective);
else SetVehicleParamsEx(GetPlayerVehicleID(playerid), engine, 0, alarm, doors, bonnet, boot, objective);
