Hi all,
Just to inform you I had troubles with tsukayu LEDs.
They are plugged as rear beam on my bike (not as turn signal), so I did not use the load equalizers as writen on tsukayu web site.
some LEds were blinking, other were off ...
Tsukayu was Ok, they sent me replacement LED twice (2 times), but unfortunately, they always blowed up .
I do not want to contact tsukayu again, because i think their led are bad material and they will send me rotten stuff again.
I solved that by replacing LED with traditional bulbs.
They are used on trucks (position light).
I had to do odd jobs a few (cut a piece of plastic) but they work fine now.
Here we are :
That heats a few but not enough to fire my bike

You can see video with trouble here
