How do I know if it works? Does the red LED light up when connected to the flash?

If you have the battery pack plugged in BEFORE you switch on the flash, when you switch the flash on the red LED will light up once. It will then light up each time the flash fires. That is the only way you can tell.

Fire your flash at full power with and without the battery pack attached, the recycle time will be much shorter with the pack than without.

I'm not certain. I just put the batteries in and use it. I notice a tremendous difference in the life and power of the flash. I don't remember whether the light comes on.

I have had it for few months and it works fine all colors flash as expected . my guess would be a possible malfunction , probably good idea to call them for replacement .

I see no reason why it wouldn't work. All it does is send a trigger to fire off the flash. I have used it on different speed lights in the past that were not listed in its compatibility description. It's small and convenient to use.

The flash is a Yongnuo (speedlite YN560). It works on some Canons, but not Rebel, as in my Canon T3i. (T3i = Rebel)

Why does when you hook it up to a cannon 600ex-rt flash the icon in flash head does nbot light up to tell you it is working with the flash? there is icon there but the icon does not light up? is it still working properly?

The infra red lights at the top light up , but it does not make a flash. All they do is come on for a split second. It will catch your eye.

It turns on if you press the red part in the center. If you manage to get it on, then you will find out that there is also a flashing mode.

No that should not be the case. i have seen few times it took longer than normal. it is typically 3 to 5 sec of hold on that button and it will turn on the flash light

The flash is attached to the lens so you need to check yoir lens has internal spiral and check the lens diameter.the flash comes with a set of adapters for different lens sizes if the right size adaptor is there then it works

Sorry, never noticed. The eyes do light up when the flash drive is inserted, but never checked to see if it blinks.

If the RED LED on the adapter is on, then the BLUE LEDs on the box should begin flashing to indicate it is charging

Mine must be newer. After fiddling with it for a while, I discovered that the red light is the reset button, and you have to push it with a pen or something and hold it down for a few seconds until it starts to flash then release it.

Im assuming thats a camera. The flash has a sync cable and slave. If your camera has a sync option it should work. If your camera has a flash it should also work set in the slave position

it should not be flashing as default, it cycles through through the settings as you click. goes like this : high-medium-low-strobe-SOS-repeat so if you just turn it on and off again, it should work

Nope! This is a flash with a relatively long refresh time. You are probably looking for an led light array for consistent light

I think they have LEDs so you see at a quick glance if they are working. Mine has a very short flash every 10 seconds or so.
