Thanks in advance.. OG .

Harley used 1157 bulbs in the front (duel filament).
The rear was a single filament 1156 bulb.
The front illuminated at all times on the one filament and then (lit) flashed the second filament when turn signal was activated.
The rear was off at all times but turned ON to flash the single filament when turn signal was activated.
I have no idea what you have installed but the front ones would be required to have a dual function and the rear needs to have a single function in order to mimic factory.
In essence the front would have 2 wires to provide positive + and rear 1 wire to provide positive + with frame providing ground at front and also at rear to each light on each side..
Then the system would need to have sufficient load (resistance) with LED use in order to blink.
You would need one resister at on each side at front on the signal wire (remember that the other wire is a running light)...one resister on each side at rear at the 1 signal wire.
This is all taking into consideration that a triple play or similar (run, turn, brake) module is not installed but then a red lens should have been installed at rear..
Also taking into consideration that nobody ever converted the rear to a dual filament system but then a red lens should have been used at rear

As mentioned, start with regular bulbs and go from there according to results.

Turned out to be some sort of coating on the little contacts of the bulb. I hit it with some steel wool and put it in and it worked fine.
