Rear Lights Flashing

[JimF2424]

Tried the beeper for a Signal Warning, it worked but not able to here it well.  Tried a louder device, only hooked it up to the existing wires to hear what it sounded like.  Well it screw thing up.  Now the rear signals don't flash at all.  Front Signals work.   The rear running light on both sides and brake light all flash on and off with the left or right signal is turned on.   Replace the Signal relay and does the same.
Not sure if the rear lights are original, please look and let me know if you know.  The buld is a 1073, with both ears the same, no offset like the 1157's.  The front takes 1157's

you mentioned a 1073 bulb. Where is it plugged into? Also did you mean the brake light on the rear fender flashes?

try plugging a bulb in the rear turn signals' sockets (below). The circuit might be still intact.

Yes. I gave that type of LED ring mid. But, there is still a bulb

I see, the led ring is for additional brake and running lights then.

Thanks for all the feed back, I removed the bulb to take a pick, when it's installed it doesn't work.  The led rings work, those are what's flashing, plus the brake light.   Will do more troulbe shooting and tracing connections.   Will update on what I find, thants again.

You may have a brake flasher unit installed. Hard to know why turn signals work up front but not in the back. Stock flashers usually won’t work if a bulb is burnt out or missing, you may have an aftermarket flasher. Sounds like po may have added a few things. Could have blown an added accessory trying to hook up beeper.

Make sure the Molex connector underneath the fender (where the two halves of the rear fender meet) is not crushed or otherwise compromised.  Had this happen to me after bottoming out the shocks with too much weight loaded on the bike. The rear tire crushed that connector and shorted out some wires, killing my brake light and making my turn signals flash like emergency blinkers. (Circled in red in attached wiring diagram).

After that I would check the bullet connectors under the right side cover.  The wire exiting the rear fender leads to the bullet connectors, which should be nested inside a malleable rubber boot. (Circled in blue in attached wiring diagram).

These steps are just to be sure the wiring isn’t compromised.  Next, check and see if there is a load equalizer installed to balance for the LEDs.  If you accidentally fried the load equalizer or compromised its wiring, that would explain LED lights flashing in unison.

Using your "beeper" in conjunction with the LED's may well be your problem. Might have to install a diode kit in the headlight bucket to isolate the left & right turn signal circuits to enable you to use the beeper.

Couldn't find 1073 bulbs in auto stores.  Ordered them from amazon.  Will try replaceing both bulbs, they don't look burnt out, but have to start somewhere.    I had the diodes on the beeper and it was working find until I tried a louder one.   Ordered the short wire harness from the side cover that goes to the connection under the fender, doesn't cost much, so I ordered it.   

Thanks again for the feed back, and will post my results.

Take everything back to stock. Problem solved.

1156 bulbs are easier to find and last longer than 1073's (both are single-filament with symmetrical alignment keys). Any reason for 1073.

[JimF2424]

Thanks for the cross reference on the bulbs.

[JimF2424]

No reason for 1073's, just that's what was in there already.  Thanks again for the reference.
