Hi

Does anyone know how to get the lens covers clear, mine are yellow! Not sure where to get new ones?

Look through your On-line Browser there are many sellers offering different products for cleaning plastic headlamp lenses, for instance 'Halfords'... you might get lucky and find a new lens for sale be (careful)  as the part may only be available by shipment from Japan...you could try Toyota Breakers for a complete light unit..I have used several manufactures deglaze solvent products over the last three years, all worked but the glaze issue on old Alphards comes back especially if you live in a Sunny environment

Turtle Wax do a heavy duty rubbing compound. With a microfibre cloth or similiar, rub this gunge onto the outside lens hard, rubbing back and forth, or round and round. Don't let it dry on, with another cloth buff it off and if you have a buffing wheel for your electric drill use that. You might have to give it more than 1 application, sorted

I have used Turtle Wax compound (not sure if it was heavy duty) on another vehicle and was very happy with the results.

Something to be aware of, I believe some of these vehicles have factory tinted headlamps, so an element of the yellowing may be by design.

 

Mine definitely have a light bronze tint to them.
