Turn Signal Not Flashing

Q:My Harley Heritage Softail 1996 indicator/turn signal lights stay on when instead of blinking. I hit the “turn” button for the signal/turn lights, but they just come on and stay on! Help!
Regards Jonny Garnder from Australia.

A:Jonathan, sounds like you have a bad turn signal module. You will find this module between the fuel tanks, beneath your dash area. Thanks, and good luck

Similar Question Been enjoying the videos and tips I have a 2008 Street glide with 90K miles on it. I always took it to the dealer until I found your website and got the premium membership. I have a problem with the right rear turn signal it lights (i have the continuous on type) but it will not flash. I have changed the bulbs, replaced the entire turn signal bar this weekend and it still did not fix it. The front turn signal still works so I assume it is not the switch. Any hints on where to look next?

A: Richard, you may have a faulty turn signal security module (TSSM). You can change it out but unfortunately, the only way to verify this before hand is to have the dealer scan your m/c.

    The wrong bulb will cause a constant on condition as well. I bought a used soft tail springer that the previous owner had put an AutoZone bulb in one of the rear turn signals. The correct H-D bulb with the correct resistance fixed the issue cheaper than a module.

    How do you disconnect and reconnect a turn signal that is being replaced?

    Ok T have a similar problem. I have an 07 883 Sportster. My turn signals don’t work but my 4 ways do. I was told by a dealer that I had to have it fixed by them because the module need pass worded. Is this true or could I buy one from Ebay and put it in myself? I am on a fixed income and trying to save some money.

    Have a 97 FXDWG. Installed a badlander load equalizer 17 years ago for run and brake lights on the rear. If the bike is not moving the right turn signal functions correctly. If bike is moving, if you press the right turn signal, it will light up, but not flash. Looked in the service manual and this problem is not listed for troubleshooting the turn signals. Any suggestions?

      Hi, Mike. Would try the signal function without the Badlands module. If the signal works correctly, the Badlands module is bad. Otherwise, you may have an issue with your turn signal module or your issue can be in your harness or plugged connections. http://www.fixmyhog.com/videos/electrical/

    I have the same problem. I did replace the TSSM yet it still does not flash. I did replace the factory bulbs with LED bulbs prior to this condition…………… any suggestions?

    I have just bought a 92 softail custom. The turn signals work on accessory mode and ignition with no lights mode but when you turn the lights on they wont work? Do you think it is my module.? Thanks

    97 XL 1200 Custom. I recently purchased this, my first Harley. It’s a very clean, low miles stock bike. After riding now for several short rides, some of the gremlins are exposing themselves.
    One problem that I haven’t nailed down the source is my left turn-signal works intermittently. It seems to be getting worse. When it’s not working, there is no signal front & rear and no signal indicator either. When working, both markers function properly as does the indicator.
    With new bulbs installed and sockets cleaned, I’ve narrowed the problem down to either the left turn signal switch or the turn signal module.
    Is one of these more than likely the culprit, or is there other probable possibilities?
    Which ever is the issue, are there test I can do to figure it out ,or do I have to start replacing parts until it’s repaired?
    If it’s the module, do I have to have the dealer program it as I’ve read some of the other customers have had to do on newer models? Thanks in advance!

    1993 electra glide turn signal indicator lights come on and stay on. directional lights don’t work

  15. william

    i have a 1985 sportster xls 1000cc it has slow turn signals real slow,how can i solve the problem?

    • Customer Service

      Hi William. Start by replacing your flasher. The flasher on your m/c is the old conventional style. It is inside of your headlight bucket unless the bike/wiring has been altered.
      If that doesn’t help, we would suggest that you begin cleaning up grounds. Old, corroded grounds can cause a variety of issues. Sometimes, on older rides like yours, the signals will flash correctly when the m/c is running and flash slowly when not running.

    my turn signals and brake light are on but when I try to use turn signals none of them flash and when I use the brake front and rear it doesn’t come on, all the running lights are on but will not flash

    • Dany

      Could it be the module not giving more power of the left mirror is like 50% less light then right one

  17. Rich c

    I have a 2009 street glide. . All my running lights are on, but when I press either brake lever my light doesn’t switch to brake. My turn signal running lights are on but when I try to use them they do most flash. Not even when I try to use the 4 way. What is my problem??

  18. Marcus

    O7 street glide …so any ideas why my rear turn signal lights don’t come on, and also left rear signal don’t work… right side signal works just don’t come on with brake n plate lights… checked bulbs both work…

  19. Dave Buckland

    Was on recent road trip and left turn signal began staying on constantly , pulled bulbs to keep from melting socket as they were hot , I had “bottomed out a couple of times and thought maybe tire had hit wiring , but dealer said (without checking) most likly signal modual …thoughts?

  20. Michael garcia

    My turn signals will not flash I replaced the turn signal module and still doing the same thing maybe it has a relay but I can’t find it any tips will be appreciated

  21. mike

    I did a set of mini apes on my 03 fatboy. I ran the wires through the bars and made all make connections. now my turn signals will not come on. all other buttons on the controls work expect the turn signals. the fuse is fine as well as the bulbs. they were working just fine before I did the bar swap

  22. Jay

    We have a 2006 street glide that the right front and rear turn signal stays flashing very dim. When use the right turn signal it works fine but just will not go out. Some times the lower rear fender shirt light goes out also? Any help would be great.

    • Customer Service

      Hi Jay. You may be chasing more than one electrical issue here.
      You may have a bad turn signal/turn signal security module or a bad speed sensor.
      However, suggest starting with a thorough inspection of your rear fender harness.

  23. Greg

    Turn signals worked on 2000 883 sportster; right rear got broken off. Replaced but doesnt flash, although left ones still do. Thanks

  24. Earl

    I know everything goes through the TSM module, as the unit has a FOB, BUT it starts easy, rides well no problems except for left turn signal.
    In my past I have rode plenty of bikes that had no signal, but in todays world where cagers play whack a mole with people on bikes-yeah its pretty important.
    If I replace the TSM, can I retrain the unit myself, for the FOB? It always seems like Harley has certain years that stuff has to be done at the dealership…LOVE THAT.
    Funny thing- when I hit the emergency flasher (BOTH turn switches at the same time) the Right comes on first (split second) but they both flash,
    so to date I have:
    1.left signal doesnt work
    2.if I hit both left and right the emergency flashers work
    3.running lamps work in front (front lamps are 2 element 1157s)
    4.left switch was checked by me and when depressed has continuity
    5. if I leave the FOB AWAY from Bike if I move the bike the lights flash for security
    6.got to the TSM and removed it (tough to do without removing rear tire) no signs of being submerged (wet pins or connectors)
    7. could this have been just happinstance? 2007 FLSTC Heritage
