Fast Turn Signals
I just installed an undertail on my 12 with the built-in LED turn signals. Now my signals blink really fast. How do I slow them down??? Thanks.

same here when u only have rear signals they blink twice as fast. when I Installed the front ones they slowed back down.
goodluck

LED's do that. there are several companies out there make modules to bring the flashing rate back into spec. not always cheap tho.

you can also put a resistor in parallel with the new 'bulbs' to bring the resistance down to standard bulb resistance.
(mine run 6-7 ohms or so)
most LEDs show as an open during the flasher relays charge cycle, this greatly speeds the charge time, which leads to the faster blink rate.
i would try an 8ohm resistor or so, as the led will show pretty much open anyway.
there are also some relays that will flash normal rate regardless of the load attached, 'heavy duty' or towing relays i think
but that eliminates the 'hey yo there's a dead bulb out there' part of things ;P
no data on those, other than knowing they exist. i just used a resistor on my flashers when i needed one

I ended up using only around 2 ohms resistance to slow my flasher back down. But the flasher itself was seeing the resistance of the relay's field coil which was around 100-150 ohms or so. Not sure what the resistance of the LED are going to be. If you do end up with a low resistance say 4 ohms or less, keep any eye on them, they get very very hot with that much current flowing thru them.. I ended up 2 ohm power resistors in a gold heatsink screwed to the subframe...

I haven't tried it but have heard that you can use an electronic flasher instead of the mechanical unit and cure the flash rate.

I'd buy it but I wanna see those LED's flash in sequence from (right turn) left to right, & vise-versa for lefties....

Use a generic, heavy-duty variable-load 3-prong turn signal flasher. They're like $5 at any autoparts store or Wal-Mart-type place.
The 3 prong flasher units have terminals marked X, P and L. The X terminal drives the indicator lights on the instrument cluster, the P terminal is the +12V power input, and the L terminal is for the load (bulbs & LED).
Cheaper and easier than a pair of 100W 2-ohm power resistors and heatsinks mounted to the frame, I think. It'll also work when you replace the front incandescents with LEDs, too.
HTH, and good luck.

Napa selles a "Load Sensing" flasher relay. It's round and has a clear shell. It is around $10.00 and installs easily!!

Actually resistors were free and its lot easier to get to blinker wiring that it is the blinker relay buried down in the battery box, and my idea will work with LED fronts as well..

personally i dont like the resistor idea but that's jsut due to a pet peeve. i like the reduced power consumption of the LEDs and sticking a resistor inline just kills that advantage. plus, i believe (don't KNOW without seeing how a bulb is wired) it would reduce the brightness of the LEDs. liek is aid, not a big thing, especially not the power consumption, but it's a pet peeve, so sue me

My blinkers have blinked faster for a blinken 3 years & haven't gone on the blink yet. Am I missing something?

I kind of like the fact that they blink faster. Sort of gives the empression that I'm in a hurry and I usually am in a hurry.

Same Here! The guys I ride with say faster is better too.
