MKIII LED conversion

Forums

Hi folks,
Is it possible to convert indicators to LED bulbs using both 062045LED flasher relay and 382LED bulbs (x4) for MKIII Commando which includes a deck flasher repetition bulb ?

Looking forward to hear about.

Please be aware of some points with LED. The LED-Light Emitting Diode, is polarity conscious, and most that are sold are made for Negative Earth. There is no need to change the bike's  polarity but it could be an option-more information if you contact me direct.
You need the specific Flasher relay, as the current drawn by the LED is so small the original flasher will not work.
The wiring colours of the wires can be unusual, so have fun with the fitting and making them work.

Are you speaking about the Flasher relay ? As being 2 terminals with no polarity as far as I suppose, why is it going to stand as a burden ? Or do you mean of something else?

Is there some wire modification to observe towards the deck flasher indicator light ?
Looking forward to hear from you.

Jérôme.
PS: as being a French, I hope what I intend to explain is understandable enough ...

Hi Jerome,
as the part numbers given are for an LED flasher and associated LED's then these will work on your commando.

On the MK3 you may also need the 'tweeker' or rearrange the wiring. if you use the tweeker then set it up with the bike running. They are so sensitive that if you set them up with the bike stopped then it will flash like mad when it is running. Best of all is not to botehr with the conversion of the headlights and stick with just converting the headlamp and the tail light. 

Thank you Ashley,

As being French, sorry not to have a vocabulary wide enough; what is the 'tweeker' ? Has the wiring for the deck flasher indicator (not a LED indeed) to be modified ?
In case of YES, I was wondering how to modify without 'destroying' the existing loom (map and corresponding loom interface)

You mean flashers instead, don't you ?

Looking forward to hear from you

Hi gentlemen,
I also own a nice imported 650cc Firebird Scambler BSA from USA.
Can I convert to LED headlight / taillight on a Commando pre MKIII basis the same ?

All the best.

You have a couple of options.

My preference is to use a modern flasher unit that has a separate line for the warning lamp.

The other benefit of a modern flasher unit is that you can use LEDs, incandescent lamps, or a mixture of both, as you no longer need to make up the magic 42 watts per side to get the flashing speed correct like you do with the original LU35048 flasher with it's bi-metallic strip.

I did an article about this sometime ago which you may find useful:

Thank you Tiller for your post.
I have always been wondering about how the indicator warning of my MKIII commando does work...

According to the standard electrical diagram (casual bulbs fitted, no LED),
standard warning diagram
when left or right front and rear indicators are activated, I am wondering about current indicator warning bulb return way to earth .

  • Is the circuit closed by mean of the 2 opposite non operated bulbs (front and rear)?
  • In such a situation how come they do not bright unless tungsten filaments are about 0 ohms resistors? They should ...

Another question if you don't mind.
Does a "LED warning light tweaker"
LED Warning Light Tweaker
does correspond to the diagram modification you mention within your article ?

Looking forward to hear from you !
All the best. Jérôme
