Look like Neon Orange & Deep Blue will be the first to go.
There are only a couple of them left so anyone that wants these colors better get 'em while you can.

Site link for ordering is in my sig at the bottom and the link section at the top.

Also, if anyone is still interested, I still have 2 Deep Green lenses that have chips out of the edge but will look perfect when installed.
Best offer over $10 on each + shipping.

Now you have one less Neon Orange

Does anyone know which lens would work best in A BMW. Dark Amber maybe?

The original empeg's Red lens is very, very close. Just a tad too red. So I'd check out the lens comparison and choose one of DarkStorm's that's as close to the original red as possible. Of course, his gels aren't up there, and I don't know if the camera he used to capture the gel images is at all close to the one used in the lens comparison.

The Gel Lenses are available at the site but the Gels themselves at the moment are through email until I get a page going for that.

Tony took the pictures for the original lenses and I took the pictures of the Gel Lenses. But I did have them color corrected by my friend who does that for a living.
