white angel eyes - new product

With the car in storage, I've been out of the game for most of the winter as I built a garage...



Last summer, I replaced my oem angel eye bulbs with 5300k colored ones... It produced much whiter rings but still, there's room for improvement.



I was just wondering if any new product surfaced that received positive feedback. If not, what is the most recognized way to getting pure white rings, without breaking the bank?
