Anyone else fitted R1 Indicators? A little help please..

Don't need cooling as such, they will be rated at 100% of their 10 watt power rating up to around 50deg C ambient, and also since they are loading the indicators which flash on/off, the average power dissipation is only 50% (about 5 watts in this case).

They'll get hot, just need a bit of space around them but no need to go out of the way to cool them.

 

Good stuff, I was hoping that was the case. Thanks for the help.

 

Glad you've got it sorted - keep an eye on the resistors to make sure they're not burning out or anything.

 

I just fitted led fronts to go with rears with relay off Internet no resistors needed even worked fine with no front indicator. Relay must use independent timing rather than using resistance of filaments.

 

Now, I beleive that the standard 'relay' is just a bimetalic strip which heats up when current flows (the light is on), because one side of the strip expands under heating faster than the other side the strip bends upwards until it breaks contact and no current then flows (the light is off). when it cools it bends down again making contact and so on. Apologies if everyone knows this already.
By putting LEDs on there there isn't so much current flowing so it doesn't heat up so much so quickly, so it tends to open a little and cool quickly making the flash rate faster.
Now I believe that the LED 'relay' is a solid state device (hence why it needs earthing) which doesn't depend on the current flowing to switch, so it shouldn't matter what bulbs or LEDs are fitted.

 

Well I ended up ordering a different relay. About 5 times more expensive than buying the resistors but looking for a plug n play option I have the ability to switch stuff in a out.

Guess I will find out soon if the Triumph Official relay is shit or electronics will continue to baffle me and I'll just wire in some resistors.

Will let you know when I do

 

It's not bimetal these days haven't seen one of those for a long time.

The standard two pin flasher is also an electronic device. The control circuit gets its earth through the bulbs since when they're off the cold filament has virtually zero resistance and the electronics in the flasher unit requires very little current.

Flasher units that work with bulbs are designed to flash faster when the load is less than they expect (are designed for e.g. 2 x 10Watts) to give warning of a failed bulb. LEDs draw very little current in comparison to a standard filament bulb so the flasher unit thinks a bulb has failed and flashes faster.

A three pin flasher unit doesn't do this, if any combination of bulb/LED fails, it will continue to flash at the same rate.

 

Excellent - thanks for explaining it all.

 

That is the advantage of using a resistor as if the connection to the LED fails the flash rate should change. I have set the resistors on mine so if the voltage drops it flashes fast. An indication of the dreaded RR failure or I have stalled it

 

Good luck. But unfortunately I had to use both 80p resistors from Maplins AND the 15 quid Triumph relay. Rears didn't need anything. All works now.

 

Success!! For anyone who wants to know,

Also fixes the R1 indicator/Triumph standard or LED combo.

Works with everything, no resistors and like G13unisol works with the ignition on and with other lights taken out or disconnected from the circuit

Happy man

 

Dammit! And I spent 15 quid on a Triumph relay, and had to get two resistors to get the same functionality!! Good work

 

Glad to see you got it working triumphmark

 

Can they get hot enough to melt anything in the infill area with all the other wires? I didn't think of this and have kind of left the resistors just dangling around in that area.

 

Either run them for a while and then carefuly touch them to see how hot they get or wrap some gaffer tape round them as this will keep them from directly touching any plastic and melting it. It will also show if its getting too hot by melting the tape.

Mine don't get anyway near that hot Hadies. I too have left them "hanging round" in the infill void.
