The latest new product post reminded me of a product my company uses in our enclosures.
And I use the 1mm jacketed core lightpipes on personal projects all the time now.
It is a low-cost light pipe that lets you channel LED light to a new indicator location.
I found in small quantities it cost far less to use these then a panel mount LEDs or a separate PCB.
They also are RF transparent and won’t contribute to EMI in wireless projects.
They have mounts for different LEDs including surface mount, and a few different lenses. Although I often use the light pipe without a lens to get a tiny point light. (epoxying them directly into a wood enclosure looks very cool)
The light pipes come in kits, pre-cut lengths, and small quantities.
It would be a perfect product for Sparkfun to carry
