Since this is the first pairs, there're lots of testing for new idea and new material. Should take a lots less for some coming up. I've seen some DIY taillights on eBay go for $199.99 and they're not even closed to looking as mine. I'll make a pair and post them on the classified forum and on eBay to gauge interest. There will be one condition that I'll need the buyer(s) to send me their cores so I can continue making them.
