LED turn signals not blinking

Hey all,

I have the Buell turn signals on my 650 and I ordered some LED bulbs for them from superbrightleds.com. Specifically, I bought the 67x15 LED bulbs:

I got them today and... they don't seem to work right. If I put all 4 in, only 1 blinks, the rest don't light up. They're not bad, as I can switch them around and always only the one rear one blinks. The regular bulbs blink fine, albeit fast.

So, question is, why are 3 of the 4 LEDs not working? Do I need a load balancer because of the much smaller current draw? Why is that? Also, where exactly would I install that?

Feeling a little dumb...

They either need load equalizers added or the flasher needs to be replaced with one that works with LEDs. I replaced my flasher with an FL-2 from http://autolumination.com/equalizers.htm following the instructions at http://vstrom.info/faq/index.php?sid...=76&artlang=en to conserve power for heated gear.

LEDs are polarity sensitive. Sounds to me like you have the + and - reversed on a few of those Buell signals.

Standard bulbs don't care.

"Unlike incandescent light bulbs, which illuminate regardless of the electrical polarity, LEDs will only light with correct electrical polarity."

True. The flasher problem alone would not cause those symptoms. Good catch. The LED flasher is also polarity sensitive, unlike a thermal flasher would be.

You guys are geniuses! I totally didn't think about the fact that LEDs were polarity sensitive, so much for my EE class from back in college

I will play with the wiring tonight and let you know how it goes. Luckily it's all posi-locks so it'll be super quick. I don't mind the faster blink rate, in fact I prefer it. With the LEDs, even the fast flashing will ensure 100% illumination with each flash. Way more noticeable in traffic than the "normal" slow flashing, in my opinion.

Thanks for the tips!

No need for the thanks. Just tell the other kids that I'm not always a prick. Besides, catching something that greywolf missed is plenty rewarding on its own.

Ok, here is my followup. Sure enough, 3 of the 4 turn signals were wired with the polarities reversed. It didn't matter for the regular bulbs, but the LEDs definitely cared. I spent about an hour fixing the problem and now all of the LEDs are installed and working.

In addition, I also installed the "extra bright" brake LEDs from the above-mentioned site (I think the same ones Greywolf mentioned in another thread). Boy, what a difference! I'm very happy with the results, so thank you for the tip to the quick fix.

I will be installing the new Admorelighting lite bar next weekend, so look for a post from me in the related thread once that's done.

I tell you guys, between the wired Givi trunk, the LED bulbs and soon the LED lite bar, the back of my Wee looks like a Christmas tree... a very fast Christmas tree

And for the record, Heavy is NOT a prick. You can quote me on that
