BCE0022: Cannot convert 'boolean' to 'UnityEngine.Light'.

hello i have an script and i get this error what is the problem

var lightb: boolean = false;
var Player: GameObject;
var lightq: Light;

function OnTriggerEnter (colidster : Collider) {

	if(colidster.collider.tag == Player.tag)
    lightb = true;

}

function OnTriggerExit (colidster : Collider) {

	if(colidster.collider.tag == Player.tag)
	lightb = false;

}

function Update () {
lightb = !lightb;

if (lightb)
	
	lightq = true;
	
if (!lightb)

	lightq = false;


}

this is the error: BCE0022: Cannot convert ‘boolean’ to ‘UnityEngine.Light’.

if you mean to turn the light on and off use lightb.enabled = true and lightb.enabled = false

You have lightq set as a Light object, you either mean to have that as a bool or you mean to use lightb.
