How do I install LED turn signals/brake light/etc on my 1980 GS750

[posplayr]

Steve has a diagram describing a two diode solution. I have never dealt with it so do not remember the details.

That said, you want either directional side to power the LED indicator but not feed the other side.

So you would wire from either directional side through a blocking diode (banded cathode toward the indicator light). This way current can not go from one side to the other, but rather only through to the indicator.

could I just have to toss a diode on the flasher relay itself with this new one? Oh and are the front lights running lights too? I can't remember now!

been a while since I've been on the forum. Steve?

You can design it anyway you like. However, if you want it to work follow what i describe.

I understand how a diode works but when I install them they both still blink when either the right or left is switched on. Just wondering where I'm going wrong or if it has something to do with the turn signals themselves. In comparability etc.

[thkbaron]

ok. I'm dumb. someone earlier I think already explained this to me. I forgot I have an idiot light for turn signals that's no longer working since I installed the signals. but that's my back feed problem I'm sure since I only have one light!

[thkbaron]

At least I’m assuming this is the problem someone else can correct me if I am mistaken

And any links to the led indicator bulbs for the dash?

turnindicatordiode_schematicforLed.jpgThis is for a Honda with a SINGLE dash indicator. For SUZUKI, the wire colours converted are are:
Honda lb,O =Suzuki lg(light green), B (black)
Honda G=Suzuki B/W(black/white stripe=ground)

so...you need ADD a wire to tap into a handy B/W wire nearby.

If you want to dispense with the incandescent, you can replace the diodes with tiny 12v leds,tuck them in the same hole in the gauge OR mod the dash and have INDEPENDENT 12v leds for left and right indicators.

Your led turn signals will NOT function independently with the original dash indicator's wiring. The bulb in the dash with the original wiring CONNECTS all turn signals together. They work with this bulb in place because your new leds draw very little power and the incandescent bulb is seen as a small resistor to them-nothing more.

Hey thanks for the help everyone. I got the electronic flasher all done and the rest of it. Selling the bike tomorrow. it didn't last a day on craigslist. I'm going to miss it. It was a good bike but I'm back into a new one now. I didn't have any problems in six years with it. Hopefully it treats the new owner just as well.

Did you replace the flasher? If so what did you use?

Nothing to design, all the work has been done for you.

I have the chrome version on my bike. Got them at Auto Zone for less than $10.

After reading this thread I'm going to stick with the stock lights. But.... I do like this license plate frame. It looks like an effective way to add visibility to the bike. Is it a straight forward install? Does it play nice with the stock turn signals? Thank you.

not really. Diodes are better and, even better, you can nowadays get tiny leds with the same sockets (is it T10? I'd have to check-it's been awhile since i fiddled...) that run straight from 12volts (ebay) and . I have the whole dash lit with them on a couple of bikes. They are really cheap because some of them don't agree with the 'CanBus" of modern car computers so they're dumping them.

I was planning to replace my turn signal bulbs with LEDs with built in resistors. Any downside?
