Question Rear brake/running light LED issue

Installed an LED 3157 in the GF's 2004 Sportster brake/running light, now when following her I have noticed that running light will flicker and sometimes even go out, with the standard 3157 there was no issue.

The brake light does seem to work fine.

Some LED`s are too wide at the "flair" to fit the socket well, they vibrate and flicker
I went to these to avoid the issue

Check that the wirs to the LED are not loose or broken.
I put one in mine, had the same issue. Found that the LED section was loose to the plastic socket. I took it apart and put it back together with siliconne; fixed.

I've put a normal 3157 back in for now, going out for a ride tonight with the GF will keep an eye to see if the regular bulb is also flickering.

eighteight the rear tail/brake light on the GF's bike uses a 3157 blade style bulb, it seems to plug in fine. I have the same LED bulb in my Sporty that I tried to put in her bike and don't have any issues.

sirrom1 was that just a 3157 bulb or the complete LED tail light assembly?
