One Automotive LED Driver PCB passed every metric in the lab, then flickered on the road because of a transient pulse from the battery \u2014 the fix ended up being TVS clamping and soft-start timing. An even more hidden trap was the LED's own thermal behavior, which an electronic load simply can't reproduce once junction temperature climbs and forward voltage starts to drift."}
