LED turn signal relay

I briefly looked for an existing post on this topic but couldn't find one. I just bought some really bright amber 1156 LED's for my turn signals and I need to purchase the correct turn signal flasher relay. Anyone have a good source for this? Is this something I can buy at my local Advanced Auto Parts?

opie - I got mine from superbrightleds.com, sorry I do not recall the part number but they have a very informative website. Good luck!

I think this is the thread you're thinking of. I'm planning on doing this at some point as well.

This can also be done cheaply and easily with high-current wirewound resistors spliced in the turn signal circuit/s. Plenty of threads out there on the interwebz on how to do it, a little bit of trial-and-error to find the right ohm required. One trip to Radio Shack and $5 or so, Bob's your uncle. I run that solution on the Suzuki.

A little more information. You get hyperflashing when you substitute LED turn signals due to the relatively low power consumption of the LED unit. Lots of science from there, but suffice to say it hyperflashes as a result. Solution is to install big, brawny load resistors in parallel with the LED signal, not in series. You trick the flasher into thinking it has an incandescent load connected. Typical resistance in the vicinity of 30 ohm or so, YMMV...

It was probably brought in to the US in '06, along with lots of other scoots. I'd say go for it, in a month and a half you might just have it running. Smile

My local O'Reilly had some resistor kits for this purpose. Indeed, most flasher units are designed to flash quickly if they think one of the bulbs is out - this is so you'll notice and make repairs. LEDs use so little current that flasher units built for incandescents indeed are tricked into thinking there's a burned-out bulb in the circuit, as Mike indicates.
SuperBrightLEDs.com indeed has replacement flasher units for folks who go down this path, but the problem may be compatibility - some hardwiring might be needed, rather than having the right plug-and-play connectors. Of course, wiring in resistors means hand-work, too, so pick your poison. If I recall correctly, the 'universal' flasher sold by SBLEDs was able to work with a mix of incandescent and LEDs, in case people don't switch out front and rear.
