I received a shipment of LED light bulbs; they are a very specific design for a particular custom application. I wanted to test them to verify they functioned as desired. So I connected a pair of test leads to a motorcycle battery that is sitting on one of my work benches. All of the LEDs displayed a "flashing" behavior, alternating in a "high and low" brightness. But these were supposed to be a constant, single-brightness type....not flashing. Therefore I emailed the seller to ask if possibly they sent the wrong ones. Their reply stated they should be correct and asked me to video the effect for them to see. When I reconnected the test leads to make a video I found they no longer flashed, but remained constant as they should. This took me a while to figure out. Apparently the first time I tested them the battery was connected to a "maintainer" charger, while the second time I tested them it was not. I assume the first time the "float" feature of the maintainer was 'pulsing' the voltage (to maintain the charged battery) and causing the LEDs to 'flash' as the voltage pulsed. Does this seem correct? Otherwise I can't think why else they flashed one time and not the second.
