my ride has (had) the stock Suzuki turn signals since restoring the bike the year before.
decide to Order some (ebay) new saddle bags Fiberglass wire rimmed black with locks And bulb lights (wanted to lock up my tools and rain gear) big enough for rain gear my vest and tools etc..
As often happens the front turn signals don't pull enough Amps now that the rear signals are Leds and wont flash after this type of mode
( used a bright white led light style 48 SMD draws 270ma and Yellow 8 led strip)
Found the easiest way to get the LED and bulb turn signals to work is to replace the stock left side turn relay with a 2 pin (1979 1000E)stock setup. Used the Novita # LL552 at advance auto for 6 bucks.
Removed the Suzuki solenoid style flasher relay and plugged in the #552 and done flashing away. (note had to add a tyrap base tie with a tyrap as the fit is loose also the tyrap makes it easy to hang back on the post for the original relay.
the Front turn signals are still Suzuki original Bulbs the rear are my choices of leds and they are Brighter then my stock tail light Videos below. one is at idle and the other video is running around 3K rpm forgot to jog down the RPM after doing some testing.
