Help with fitting LED indicator bulbs

[KevinB]

I bought some LED bulbs, but as we know, they don't work with the original flasher unit. They don't flash.

So I have got this new flasher which is supposed to work with LEDs.

Can you please help with how to connect this in? The B, E and L.
I have also asked the seller.

Per the old wiring diagram, I have currently a green power wire, a green/brown to the indicator bulbs and a light green to the switch warning light.

Here's my current flasher unit.

PS Thanks to who brought back the message board tonight.

PPS I have my Morris back after the welding and brake work, with a fresh MOT.

Initial thoughts would be B is positive power input and E is negative earth for the flasher itself. Then L is for the lights. I'd suspect that the switch indicator light will need two inputs with diodes on each. The supplier should confirm.

I'm not particularly inspired by the Chingrish on your flasher unit......IF it follows normal convention then

B is battery so that is the plain dark green wire

L is lamps so that is the green with brown trace wire

E is presumably earth so there is no connection for the pilot lamp on the indicator stalk (light green wire)

Conclusion: the unit is not suitable as for the MoT test there must be a tell-tale lamp for the indicators. It is also only suitable for negative earth it appears.

Get one of these which I can personally vouch for. They work perfectly. Note: must be connected to earth which you can do to the mounting bolt. The bracket will need the hole enlarged with a rat's tail file. Purchase the correct polarity unit as they are not interchangeable.

Thank you jaekl and Stephen.

I was not encouraged by the language on it either! I shall have a play with it and try to understand. Hopefully without doing any damage to the car. And then almost certainly follow your advice Stephen.
