Ok so I know to get led turn signals to work I need to install a diode but I'm not all that familiar with electrical stuff anyone know a link where I can get one? Or what to search for on eBay? Also I have a 95 gs500 would and integrated tail light for gs500f be compatible? Are the rear plastics compatible? Thanks! Will

Somebody save me all I need is a link or part number trying to order it ASAP, thanks!

You need two diodes, 1N4001.  (4002, 4003, 4004 would also work)  If you have a Radio Shack nearby, check there.  Otherwise Digikey or Mouser.

The lights in your pic look like the later generation.  Won't fit without some fab work and cutting.

So one per side or one per turn signal? Thanks Paul! Yea that's what I feared

one in the whole circuit... in the E models it is usually added into the wiring in the headlight bucket i believe ... the diode just provides enough resistance for the flasher can not to freak out... (thinking) ... theoretically it could go anywhere in the circuit .. but from all the bits i read from Adidasguy in the last couple years he did it either inside or right next to headlight bucket .. ease of access i guess  :thumb:

Two in the whole circuit.  See diagram above.

If I'm not mistaken:
LED turn signals = wire in resistors or install an electronic relay
LED turn signal dummy light = dual diodes or use non-polarized led bulb(what I did)

Actually, Janx, there are 2 diodes that are necessary....but it's only necessary if you want to replace the indicator bulb with an led. Electricity flows "both ways" through the turn signal indicator bulb. For a normal light bulb, this doesn't matter. For a polarized led, electricity only flows one way. The diode mod in the diagram above effectively allows that electric current can come from either directional turn signal but the diodes will only allow the polarized led to get current flowing only in the appropriate connection for the led to light.

The diode mod really has nothing to do with replacing the turn signal bulbs themselves with LEDs. Diodes do not add much resistance to a circuit, though they will prevent current from flowing the "wrong way" in a circuit. If you replace the turn signal bulbs with LEDs, you either need to add a resistor in series with each turn signal or replace the turn signal flasher with one that can handle LEDs. If you replace the turn signal bulbs with leds and some don't light, the polarity is backwards.

Fixed it for you. There is no nonpolarized led that fits in the 2001+ (I think that's the right cutoff year for this) turn signal indicator. You should be able to find an unpolarized led that will fit earlier models. The socket size was changed along the way.

If you replace the turn signal bulbs with LEDs, you either need to add a resistor in Parallel with each turn signal or replace the turn signal flasher with one that can handle LEDs.

Unless I'm missing something...
Parallel resistors = a total resistance less then the lowest resister in the circuit. This would not help at all, series = a total resistance equal to the sum of all resistors in the circuit - this is what u want.


Nvm, the relay works off current. Yes parallel is the way to do it

my bad then ... 2 diodes in one mod.... not one mod... i always took it as the diagram above had a few bits added into the circuit but it was a one job fix...

grammatical/syntax errors  :icon_rolleyes:  ;)
