Help: One side turn signal stopped working post led upgrade

Experts,

I upgraded my Fat Boy 2014 turn signals (4 front, 2 rear) from Incandescent bulb to LED inserts bought from Amazon.

I noticed, post installing the right rear led turn signal was not blinking at all.

I swapped it with left side and same results. Only right side has issue.

I reinstalled the Incandescent bulb on the right rear and its blinking as usual.

What can be the issue here? Please help fix this issue. I have not installed any resistors or load equalizer yet.
