Hello everybody, has anyone installed front and back LED turn signals on their GRiSO? I've installed them on a vfr800 and had to get a special relay to eliminate the hyper blinking. I'm assuming (careful now) it would be the same with the GRiSO. Any thoughts? Thanx,

Yup, you'll need in line resistors. Not only to stop the rapid blink but also to prevent the dash warning for blown globes.

Yes & no. There's no relay on the GRiSO. They're controlled by the instruments, individually.

El-cheapo LED's will require resistors to prevent what Pete has already mentioned. Motogadget and Morimoto (and possibly some other high-end units) will not.

Mine need swapping out, but I didn't fancy having to bugger about with resistors.  What do I need to look for to indicate they don't require resistors on the description ?

None of them say you don't need resistors. They cover themselves by saying you may need resistors, or that the indicators will work with load resistors. I can tell you from personal experience that the Morimoto's don't need them, and I've seen reports that the Motogadget LEDS don't.


¯\_(ツ)_/¯

I'm confused Pete. Don't you mean a resistor in parallel? Any LED turn signal will already have the resistor in series, but this one will not prevent the dash warning for blown globes.

I installed LED flashers on the front of my GRiSO, and used 15Ω 5W resistors which were small enough to hide in heat shrink behind the headlight. I know Kiwi Roy claimed that a much higher resistance will still suffice, but I had already installed mine.

Rizoma LED indicators come with pair of resistors (they should do given the prices !); just minor PITA to fit them somewhere out of sight....like behind the coils for front ones.

Actually I checked it out using my GRiSO as a guinea pig.
The lamps I have worked without resistors.
Only if it throws up a failed lamp alarm will you have to add a 1K 1/4 watt resistor for just a few cents.
I would suggest soldering the tiny resistor to the lamp holder contacts.
The failed lamp symbol is there in place of the rapid flash you would get with an old style thermal relay.
Here is the thread where I talk about it
