+1 to Chris' reply. Cheaper LEDs have no built-in voltage regulator and therefore react instantly to any voltage fluctuation. You'd need an oscilloscope to pick up those voltage fluctuations.

A large but short dip will look like a tiny fluctuation... If nothing more reasonable works you might need to borrow agood oscilloscope to really see it... Old burglar alarm installers might still have a device they used to detect short breaks in the foil they lined windows with
