    I have changed over many of my "filament" bulbs "194" wedge and "7404" to LED that I bought from SuperbrightLED. Anyhow they worked fine for a period of time. I got pulled over by a "cop" telling me my right tailight is "out". I checked the "LED" on the opposing side and worked fine. So now I am "lost" on what to "check" next. I gotta drive at night.

    Thanks
    Not sure what is up, I disconnect 12v aux battery and reset everything now apparently okay.

    It could be as simple as the bulb plug was not snugged onto the bulb enough. By your reseating things you corrected the problem! Keep an eye out however, it might be a bad LED that works for a bit, then winks out, only to "Work" again when power is reapplied!

    The sockets for those wedge bulbs on the Gen II are not the best design. It's just two round wires crossing each other. The contact patch must be quite small. I found that, on the wife's 2008 Prius, that you could remove a bad bulb reinsert it and it would sometimes work. Conversely, sometimes a new bulb would not work the first times it was inserted.

    The filament "194" bulb went out on me a couple times but the bulb actually was "bad" and seem to occur/happen on weather,temp, rain,moisture and seasonal changes.

    I was thinking or considering "die eletric grease" but did not come to that

    Some of the Gen3 have filament type "wedge" bulbs for both exterior and interior applications

    No I just "tested" or "hooked" it up on opposing side socket and worked fine so I knew LED was okay, and then later checked wiring,fuse, and socket.
