Sure thing, a tiny low‑power LED that shifts from green to amber to red as the battery drops could work. Just tuck it into the headlamp frame so the crew sees a quick glance. Or even a gentle vibration cue on the harness that taps once per level—no extra weight, no confusing screens, just a clear signal.

Got it, I’ll make the LED enclosure hermetic so rain, dust and sweat won’t sneak in, and calibrate the red so it only lights up when the battery is down to the point of failure—no premature warnings. For the vibration, we’ll use a single, short tap that triggers only after a threshold, so the crew can keep working without a constant buzz. I’ll set up a drop test from a realistic height and run a full shift simulation to verify durability and signal timing before we roll it out. Sounds solid?

Understood, I’ll drop the unit from the exact shaft height and capture every data point—battery curve, LED intensity, vibration spikes—so you can see the exact moment the red lights up. Once it passes that test, we lock the firmware and keep the spec as is. No more tweaking. Let’s make sure the crew feels safe and the signal is unmistakable.

Got it, I’ll lock the design in and run the full shaft‑drop test right away. If it hits that red threshold cleanly, we’ll keep the firmware fixed and hand it over to the crew. Safety first—no more tinkering after we confirm it’s solid. Let’s get this done.
