LED Turn Signals Not Functioning

I purchased a set of front/rear LED turn signal bulbs from superbrightleds.com last week and they only seem to work correctly if I leave one of the regular bulbs (not LED) on each side, otherwise when turning on the signals both signals turn on.

Because of the reduced power draw, I'm guessing there's something that needs to be adjusted with the actuator. Does anyone have any suggestions? Right now I've left the rear LED turn signals in and placed the original OEM bulbs back up front so the turn signals function correctly. Any help is appreciated.

If memory serves, this flasher is a plug 'n play LED flasher.

CAVEAT: Following post may be irrelevant; off-topic. Yet, it shares the LED turn signals topic.

A riding partner had LED turn signals; worked o.k., except . . . dashboard indicator light did not flash when signaling a turn in one direction; worked o.k. when signaling a turn in the opposite direction.

Problem lies in the directional flow of current through the LEDs, versus the two-way current flow through incandescent bulbs. The KLR wiring design, assuming incandescent bulbs, connects the dashboard indicator light for this either-way current flow, ineffective with LED turn signals when switched in one direction.

Solution: Diode implants, permitting the dashboard indicator light to accept current of either polarity. IIRC, one side of the OEM incandescent dashboard light must be permanently grounded, the other side connected to two diodes, each accepting current from its appropriate turn signals and blocking feedback voltage to the other turn signals . . .

Circuit online on 'Net.

Again, regrets if this post is of no relevance or interest.

Good info and hanks for posting this. I've not had this problem (yet) but will reference it if I do.

Do you (or anyone) know where the new flasher needs to be plugged on the bike? Any input is appreciated. Thanks again

Looking at the back of the instrument cluster on the Gen 2 just to the right of center as you face the bike you should see this relay mounted in a rubber holder:


The flasher I referenced should be a direct replacement, except that the female connector is on a pigtail.

I replaced the flasher as indicated above; however, I'm having the same problem as I was having before changing it out. When turning on the turn signal (left or right), both signal lights turn on. When I place a regular bulb in the front turn signal spots, it operates properly but not when all bulbs have been replaced with an LED bulb.

Thoughts?
