so I have done a LOT of research and found a MUCH cheaper solution. the ones you want El Presidente are just like the factory ones, but the amber is clear and smoked, and the back up is smoked as well.

you can achieve the same look with your very same lenses.
you might cringe when you read it though - but give me a chance. VHT Nite Shades sell a product which is a spray-on paint that tints plastic lenses - it is a transparent black paint. it takes at least 3 coats to completely black out a lens. but if you do one or two coats over the desired area, it gives the nice, even 'smoke look.' i know a few members have done it to their tail lights. and ive read through an exhaustive list of forums talking about how to do this and determined that it is quite easy, the quality is great, and the risk is low (you can use paint thinner to remove the paint). also you don't sacrifice light output.
i bought a bottle today from

they are cheapest retailer for it, plus free shipping. im going to try this out on one lens first - it has a chip in it anyways. ill post once ive done it.
this guy gives a detailed tutorial on how he did his Nissan Z. he goes into wet sanding and polishing, BUT according the product you can get away with no prep work other than cleaning.

first, ill sand the entire lens. then ill try doing 1 coat over the entire lens. then a second coat over the amber and reverse sections. then a coat of clear coat followed by polish and wax.
thoughts?
