Any lenses that I would make for sale would not be DOT approved, and for "offroad use only".
Pricing would still be high, but less than the $800 mark I'm assuming with a few committed buyers. I'm guessing that 'tooling up' using this method would run somewhere in the $750-1000 range.
Heck, I would have to pull some tails apart to see if the method I'm considering would even be viable, which would require the user to cut their OEM lenses and do a little bonding, or send them in to have them converted over to a JDM/Euro reproduction.
Honestly, I bet Clearz can produce a higher quality lens for less than what I could charge.
They were doing clear turn signals at one point, right? Maybe a place like ZCCJDM or MSA would be interested in contracting Clearz for the lenses since they could make the initial purchase in bulk, making it worth both company's time.
