Using LED turn signal bulbs with LED flasher relay
Ok... so here is the setup for using LED turn signal, LED turn signal indicator on the dash and using an LED flasher instead of load resistors:
(although you will find this will be needed even using an incandescent or you will have a much weaker indicator light using an LED flasher - at least on mine I could barely see the incandescent light up)
NOTE: I did this with the diodes up inside the enclosure for the indicators simply to keep them from moving once completed. You could also wire these diodes in down at the bullet connectors for the turn signals and splice that to the dark brown wire down there, but they may be more susceptible to movement that may lead to an open wire over time.
So this mod was just for indicator bulbs in cluster? It seems like more work than benefit? I get doing LEDS for actual turn signals, but why do those?
Perhaps I am not following this correctly.
The indicator won't work correctly with an LED type flasher unit (incandescent or LED bulb - you just get a VERY dim indicator with either type of bulb), plus I switched to an LED indicator bulb for the turn indicator that is much brighter than the incandescent just to catch my eyes and I don't drive with it on like an idiot which I have been known to do. You really have two choices
1. Using resistors to imitate the load of an incandescent turn signals so the stock flasher doesn't hyper flash
2. Using an LED flasher that flashes at the same rate regardless of load, but you'll need this fix (which is basically how other bikes are already wired) so the indicator works properly.
I personally hate the 6 ohm load resistors as they are more of a pain than this fix to mount and ensure they are attached to something that provides a real good heat sink or they will burn up and/or melt something else, so I'd rather use the LED flasher and to me I think this is far less work without the concern of the resistors burning up. I've also been cutting wattage all over the bike. The one in the instrument cluster that really is only useful for power conservation is the high beam indicator as it is the only one that might be on for any length of time. While on, with the LED I have in that spot I free up about 3.2W. Aside from that, their lifespan is much higher as LED's are less susceptible to vibration and shock killing the filament.
