Why Is My Cue LED Faintly Glowing Red When the Module Is Armed?

Some COBRA firing modules show a faint red glow on a cue LED when an igniter is connected and the module is armed. This is expected behavior on B-hardware modules. It does not indicate a hardware issue and does not affect module performance or safety. Older A-hardware modules may not show this behavior.
