    Hey guys I have a 1960 Studebaker Lark. I have the right side brake light that always stays on. The blinker works but it’s faint. Both filaments are lite. Left brake light works fine

    If you are sure that the wiring is right,dig into the turnsignal. The brake lights are used for turn signals as well as brake lights. The turn signal can power the brake light on independently of the brake switch and the flasher simply interrupts the brake light circuit.

    Sounds like the turn signal switch, or a short in the wiring somewhere. First I would change the bulb for a known good one. Just in case.

    “Yep” that would be your turn signal switch touching inside !!!

    Are you sure the bulb isn't half way in with both filaments touching the button in the socket..

  7. I'd check the socket first to be sure it isn't corroded and that the ground is good.

    Check all your grounds! A bad ground can do some pretty weird things.

  9. Try changing the bulb first. I had an OT car that I chased for three days after work on the tail lights doing what you just said. I checked all of the bulbs first and they were OK. Chased all wiring and ground issues then back to the bulbs. One had a filament broke shorting to the other filament causing all the headaches. Finally found it by changing the bulbs out one at a time. Yes the bulb in question still looked good even under a magnifying glass but it was bad.. Try changing the bulbs.

    Turn signal switch rear right turn contact is always making contact to flasher terminal on switch. In this case the flasher will only have one bulb load when in straight position and therefore will not flash but will light. Wiring short doing this is also possible.

    Check and double check grounds
     
  12. @32highboy54,

    I had a similar experience, and it was a ground issue feeding back through the bulb. If the originator of this thread hasn't checked up on it lately, we can be sure that it is likely to help others.

    perhaps as happens too many times the problem was solved.but they never post back they lack the decency to do so.some wonder why the lack of response to some requests for help go unanswered this is prime example why.

  18. Never entered my mind until now but a good thought and also entirely possible. Maybe from now on when they have a low post count I will skip answering. Trying to help people that do not appreciate it does get old.

  20. My list....
    for anyone else who may run into same prob.

    CHECK ALL GROUNDS. If a ground gets dirty or unreliable, the current will find a different path. A most common happening is the blocked current making a turn and borrowing a nearby or a far away filament of another bulb as it's path to ground because it couldn't find the right path because of being blocked by a bad ground.

    Check the bulb socket, and CLEAN IT.
    I have seen some contacts inside the socket have some recessed "buttons" due to overheating or corrosion. You may need to replace the common socket contact "pigtail" unit.

    Studebaker turn signal switch...
    My Hawk will have that problem if I don't make a deliberate effort to make sure the signal lever is centered as it should be. You cant count on a worn switch to stay i the center position.
    I have also seen worn or recessed contacts in the turn switches that do the same.


    For quite some time now I have contemplated using my 3d printer to make myself some polycarbonate copies of my Stude signal switches but I haven't had any spare time yet.

    There’s probably more going on in this person’s life than his Studebaker brake light. No need to be derogatory.

  23. OP still has not been back since he originally posted on the 7th of Feb. Unless he is counting grass roots he does not deserve any more responses.
