They weren't all that deep with the overlays. They colored the light some, but not much.I had some amber overlays from bluebatmobile before ToolGuy's fogs, those were definitely deep. But didn't look like the Lexus yellow since they were more orange. Along the same lines is Lamin-X, you can find that here:

I don't trust any of those fancy expensive bulbs, they never last. I found some ricer ones available in yellow before I went with the batmobile things but figured the clear bulbs with an overlay or something would be a better idea.I liked the look of the yellow fog overlays from Toolguy, and you never know - while you haven't had trouble, you may someday. Pretty goofy idea having glass down that low.
