I am in the process of building up yet another light for my bike. This one has 6 xp-e with 10mm square carclo optics. I need a protective lens to slide into the front of my light housing, needs to be 1mm thick and approximately 12mm x 65mm. I am open to glass, poly carbonate ect. I am currently thinking about cutting a plastic window meant to go over a welding shield. I want something with good transparency that I can cut to the desired size mostly to keep it cheap, I dont have tons to spend on this so paying lots of money for custom cut glass is probably out of the question.
