Led bulbs - flasher issue

[HWKWallis]

Has anybody here successfully replaced their incandescent bulbs with LEDs.
Thought I had success all round until it came to replacing the flasher unit with an LED one but now I get all 4 indicators showing and no dash light.
From what I can find relating to motorcycles a fix for this this appears to require wiring diodes around the dash indicator light?
Anybody been down this route and can confirm?

Thanks

Jim

...relates to Amazon 1967

Hi Jim, Not Diodes, they need to be resistors 50 watt 6 ohm should do it. Luckily motorcycles are my thing!

See here for how to wire them https://www.motorcyclepartsstore.co....l-motorcycles/

Cheers Nick.
Suspected that imitating the load from the old bulbs may be an option
Will have a look at suitable locations these could be installed ; had hoped not to be cutting the loom around to any great extent.

Morning a simpler solution is to replace flasher unit with LED compatible unit

far more consistant remedy & makes no alterations to wiring harness

Hope it helps

Yes... I did swap the flasher unit for a LED specific one and as I have it would be home and dry if the amazon had 2 tell tale bulbs on the dash.
The guy who supplied the kit came back to me and concluded sight unseen that the single tell tale is being used as a route to earth for opposing sides and allows for the lower LED to leak to all indicators (or somesuch).

So the answer seems to be either replicate the original resistance of the old bulbs with new resistors in circuit or, which is what I will try first I think, stop the flow of current both ways by placing diodes inline with the circuits touching the tell tale bulb and earthing that directly!

Thanks to both

Jim;

"The guy who supplied the kit " had it right!...the single Indicator Lamp design makes use of an electrical trick, and this trick does not play with the LEDs. If you post one of those diode circuits, or post a link, I'll have a hard look at it and let you know if it can be used as is or what mods it needs.

Waiting for the "kit" to arrive but understand I am wiring a diode (1N4001?) inline with both the blue and green respectively which feed the bulb at the present... Then joining those wires together to feed the bulb and also providing a new earth to the bullb.

Pulled the bulb out this afternoon and without it flashers now work so hopeful of the logic and access!

If a diagram arrives will post for a confirmation if you'd be kind enough... Getting the diodes around the right way being imperative.

Update:

Received the diode loom as per attached and installed which seems to have worked.
Kit came with crush connectors which I never have any luck with so substituted some spade ends which I also soldered.
The wiring was cut and inch south of the bulb, and diodes inserted on the green with blue going to earth (I made up a longer black earth line and tethered this along with the new flasher earth by means of the screw which holds the original flasher clasp).
Used some insulated spade to spade connectors to install so its easy to remove etc.
Working under dash was made easier in the first instance by unthreading the bulb connections towards the left side of the column (RHD).

Objective with the LEDs was reliability, longevity, and improved vision.
Former remains to be seen; but certainly their are a significantly visual improvement over the incandescent versions.
As per photos, I used amber bulbs for the indicators and red for the stop lights along with bright whites.
I also did the headlights and managed a concealed fitting solution by cable ties to the back of my plastic inner bowls and some additional heatshrink on the now exposed connector block (although these are shielded also by inner arch protectors).

True to current luck, after a couple of time merrily switching between high and low beam via the footswitch that broke....so waiting on a replacement from Brookhouse.

best

I think that you'll find that using white bulbs/leds will always give much brighter lights when used behind coloured lenses.
