I don't know why as it seems to be all correct and there are no errors in console. It always starts on green.png and stays there? I'm trying to make a timed traffic lights sequence that can start as soon as the page is loaded without a button.

<h2>Traffic Lights Program</h2>
<div class="light"><img src="Blank.png" style="width:100px;height:228px;"/></div>
<script>
trafficLight = "green";
var trafficLights = ["Red.png","RedYellow.png","Yellow.png","Green.png"]
function green() {
document.images[0].src = trafficLights[3];
}
function yellow() {
document.images[0].src = trafficLights[3];
}
function redYellow() {
document.images[0].src = trafficLights[1];
}
function red() {
document.images[0].src = trafficLights[0];
}
function yellow2() {
document.images[0].src = trafficLights[2];
}
function automatic() {
if (trafficLight = "green") {
setTimeout(green(),500)
var trafficLight = "yellow";
} else if (trafficLight = "yellow") {
setTimeout(yellow(),500)
var trafficLight = "redYellow";
} else if (trafficLight = "redYellow") {
setTimeout(redYellow(),500)
var trafficLight = "red";
} else if (trafficLight = "red") {
setTimeout(red(),500)
var trafficLight = "yellow2";
} else {
setTimeout(yellow2(),500)
var trafficLight = "green";
}
}
setInterval(automatic(),1000)
</script>
