Folks,

I need an LED relay flasher pronto, as in today. One of the ones which are variable load I believe and allow LED bulbs to be used. Halfords have 9 Flasher relays listed on their website but none of them mention LED use. Could really do with one of these today instead of ordering online, any ideas where else stocks 'em on the high street? I think its a '2 pin' type I need.

Ta.
 
I guess you'd have to find motorbike part dealers.

Jim Allan Motorcycles Ltd - Falkirk
208 Grahams Road, Falkirk FK2 7BX

Start with them as they have a workshop. I know my local dealer has a big range of LED indicators so I expect they'd stock the relays also. Personally I got mine online.

I see you've also got morven motorcycles. But closed on wednesdays....
 
might be easier to use a resistor . I just went through the same hassle with the Tuono and the 3 led friendly relays i bought didnt work.. so fitted resistors and jobs a good un
 
They fit inline with the indicators, so from stock loom - resistror - indicators
No idea what resistor you need mind :D got a maplins local?

Shame HG went under, they used to be perfect for stuff like this.

They used to sell ones that looked like this, prob helps with how the wiring should look also:

I had to do this on the fly a few weeks ago too. Do you happen to have fast flashing LEDs and an MOT soon? haha

The diagram Snaggle posted is what you need to do. Think of it as trying to short the +ve and -ve with a resistor.

What you need is any old resistor about 5-10 Ohm, but it needs to have a high power rating (25W is ideal) to be able to deal with the current that goes through it.

I managed to get it to work with a 10 Ohm resistor rated at 0.1W (yes, zero point one). After about 10-15s they would burn out and the indicator would return to its usual high flash rate, but it was the only resistor I had in my "fun box" under 1k Ohm. So I wired it in and hoped the tester didn't leave them on for too long!

Below is a pic that my be useful, it's the same as the diagram above, only it's burned out! I just pushed the resistor into the connections where the indicator meets the wiring loop, connecting +ve to -ve).

Tip: Don't hold the resistor body, I got a nice resistor shaped burn on my fingers the first time I tried these resistors.

Hope that helps!

EDIT: Maplin have a 10 Ohm 10W resistor that could do the job. It might be useful to get a crimp set too.

Cheers guys, I'll investigate the resistors. My set up isn't the usual x4 LED blinkers not flashing/flashing at an incorrect rate. What I've got is a rear tail light which has integrated brake lights and indicators in the same large LED bulb. The front blinkers are stock 10w bulbs. Someone has said on another forum that they had a similar setup and solved the issue by swapping the front 10w bulbs for 21w bulbs. Not really sure how that works, something to do with the load/resistance changing?
 
Basically each side needs a load around 20W, if I'm not wrong most led indicators use less than 1W (my led indicators use 0.6W), so you can swap the 10W bulb for a 21W, but remember a 21W will generate more heat, I'm not sure if this extra heat will damage the plastic on your indicators, but I don't think so.

Or you could add a load resistor in parallel with the led indicator

each standard indicators = 10W divided by 12v = 0.8333A

so the resistor needs to be 12v / 0.8333A = 14.4 ohms

I think the closest one is 15ohm, ideally you would need a 25W, but probably you can get out with the 10W ones.
