The Driver Station software, FirstTouch I/O module, cRIO, speed controllers, relay modules, wireless bridge, and batteries shall not be tampered with, modified, or adjusted in any way (tampering includes drilling, cutting, machining, gluing, rewiring, disassembling, etc.), with the following exceptions:
Emphasis mine.
What components? Kit parts or components you make?
If it’s the former, then you might try using some cheap fiber optic cabling you see in light-up toys to run the light to the outside of the chassis.
