LED position lights go dark out at same time

[racer1735]

Seven months ago I replaced my OEM marker lights with Sylvania Zero LED. I will also add that I have replaced the headlight sub-harness. Tonight I get back from a ride and notice that BOTH of my marker lights are not functioning. All other lights are functioning, signals irk, headlamps work, brake lamps, etc, so don't think it's fuse-related.
I'm going to replace both lights but am curious if this is an issue specifically related to these lamps? I have already purchased replacement lamps which are the identical LED but if they burn out quickly I will go back to the dim OEM bulb.
Anyone else have this issue ?

To wrap this up (at least until they go dark again), I pulled the headlamp housing and removed one of the position bulbs. For whatever reason, rather than immediately installing a new bulb, I rotated it 180 degrees and reinserted it into the socket. Turned on the ignition and it worked! So put a light coating of dielectric grease on the connector, moved to the other bulb and same result. Go figure. The bulbs state if they don't work to rotate 180 degrees in the socket, but I was assuming that's if they don't work upon installation. Mine have been functioning and just recently wen dark. At least now I have a set of backups for next time.
