I'm going to fit some LED indicators to my FZS600, they're rated at 2 watt each.

What rating resistor do I need?
Do I need a resistor for each indicator or can I run both indicators a single resistor?

I would guess at 330 - 470 ohm but you realy need a datasheet for the led to work out the best voltage and current for them, best to use one for each so you don't have to mess about with the main wiring loom.
If they are ready made indicators they probably have resistors built in.

can you get a flasher relay specifically for LED indicators? saves messing about with resistors.

I agree. They're only about £5 and you won't have the problem of finding somewhere to mount resistors where they can dissipate heat safely, but if you do want to continue with the existing flasher you'll need two resistors of 4Ω each, and they need to be rated at 25W.

I've bought resistors but the relays are available and I don't mind taking the resistors back. What do I do with relays, do I need one per indicator?

, just found this:

Looks like I'm takin the resistors back, looks far easier this way

DryRob · « **Reply #6 on:** 14 April 2012, 01:08:51 pm »

what type of relay do I need? There seems to be 3 types available, 3-pin, 2-pin and plug in.

OEM block type on the drop down menu. £12.99

Looks like it has the same plug as the one in the post you linked to.

If you're looking on a cheaper website look for something similar............ like this:

I fitted mirrors with in built led indicators and removed the orignals on my Tuono
I used two of these http://cpc.farnell.com/welwyn/wh25-6r8-ji/resistor-25w-5-6r8/dp/RE04134 wired across plus and neg to slow the flash rate ......works fine

if you were anywhere near swindon ,george whites stock is being sold off and there are some indicator resistors there cheap,i was looking at them yesterday but have no intentions of getting led indicators

Dead Eye · « **Reply #10 on:** 16 April 2012, 08:27:02 pm »

Is George Whites shutting down up there!

I've been meaning to head on up and take a look around again.

george whites are no longer but all of their stock is for sale,i bought a few things and saved a lot of money,like a thatcham approved disc lock for £8,a yamaha tyre pressure gauge for £1,a spindle key for £2,they have a lot of clothing going cheap,if there are any petite ladies wanting bike gear there was leather trousers for £9 ,or if you know someone is big they also had some trousers,there are also more expensive things there

That sucks, typical that I find this out the day before leaving the country for a holiday :P Hopefully they will still have some things around when I get back...

DryRob · « **Reply #13 on:** 17 April 2012, 11:56:42 am »

Thanks for all the advice, I've ordered a relay off ebay and will let you all know how it pans out. Unfortunately I'm nowhere near Swindon...

The use of a red LED is a popular choice. I don't trust just a resistor[/size]and an led strip lighting in series across an AC line voltage of 120. I suggestthat you use an adaptor with an output of 12 Volts AC. This willextend the life of the led strip lighting outdoor with the use of a 470 ohm 1/2 wattresistor in series. Why the adaptor? This is used to keep powersurges from destroying the LED, which I have seen happen.If a surge happens, the voltage spike will be lost in the adapter'stransformer. Why 12 volts AC output? this is used because anLED only conducts electron flow in one direction. This means thatthe 12v led light bars will flash at the rate of your line voltage, which is 60 cyclesper second here, in the States. In Europe, it is 50 cycles. 60 is justfast enough so that the eye doesn't see the flash rate. 50 you cansee a flicker, but you can get used to it, after a while. This is assimple as I can explain it to you. It will be dependable, too. Feelfree to e-me. I will be happy to give you more information and helpif you need it.

errr... ok.

At least with the bike limited in range to the length of your mains extension lead the police will be less likely to quibble about the indicators being the wrong colour.

DryRob · « **Reply #16 on:** 21 May 2012, 12:16:19 pm »

if by adapter you meant new relay I went for that and the lights are flashing at a reasonable rate now. I will rely on the fuses to protect the LEDs and I believe the supply voltage from the battery is 12V so no need for an adapter. All in all it took about 1.5-2 hours and my bike no longer looks like Plug from the bash street kids so I'm happy.

what about a fzs 600 on a v 1999?

DryRob · « **Reply #18 on:** 22 June 2012, 09:15:50 am »

I think it will be the same but don't know for sure

Welcome to the forum. I will e-mail you for help. This weekend I am installing new indicators to my house.

i got a led relay from halfords & it works a treat if thats any help
