class property to eloquent parameter

class FindCustomer extends Component { public string $codbar = '';

public function find(){
$customers = Customer::with('lightbulbs')->whereHas('lightbulbs', function($q) use ($this->codbar){

});
(...)

What I wannt is to pass a parameter to the whereHas function so I don't have to do:

(...)
$codbar = $this->codbar;
$customers = Customer::with('lightbulbs')->whereHas('lightbulbs', function($q) use ($codbar){
(...)

Any help, please?

Alberto.
