Material emission flicker using javascript

Noob here. Creating a flickering light fixture. The bulb flickers, i wanted to just tie the emission material to the flicker ive already established.

My goal is to tie the lightobject flicker and the emission material together so the material matches.

Below is my script. Forgive the noob(ness?) :)

var flickerLight : GameObject; var Brightness : float; var LightBulbMaterial : GameObject;

function Update() {

if (Random.value > 0.8 && flickerLight.GetComponent.().intensity == Brightness) { StartCoroutine ("FlickerLightTexture"); } }

function FlickerLightTexture (){

 while (flickerLight.GetComponent.<Light>().intensity >= Brightness)
     {
     flickerLight.GetComponent.<Light>().intensity -= Time.deltaTime*30;
     yield WaitForSeconds (0.1);
     }

 while (flickerLight.GetComponent.<Light>().intensity <= Brightness)
     {
     flickerLight.GetComponent.<Light>().intensity += Time.deltaTime*30;
     yield WaitForSeconds (0.1);
     }

     flickerLight.GetComponent.<Light>().intensity = Brightness;
     LightBulbMaterial.GetComponent.<Renderer>().material.emission.color.intensity == flickerLight.GetComponent.<Light>().intensity;
 }
