LED flasher unit

[Marden]

Hi. New member here. I have a strange problem with a new LED headlight installation on my very old VW. I've recently installed a set of ebay LED headlights and tail lights on my old buggy. They're the ones with an outer ring that swaps white/amber for the turn signal. They're running through an LED flasher unit and the problem I'm having is that they function fine when used by themselves, but when the outer ring is lit. the front will remain solid amber while the rear continues flashing. They're both on the same circuit running through the same flasher, so how on earth can one remain solid amber while the other continues flashing? It's driving me nuts, so any help would be greatly appreciated. Thanks in advance. Mark.

Have you checked the earth connection(s) on the front lamps

I didn't really trust the chassis for earthing, so I've run dedicated earths for all the lights directly from a negative bus under the hood.

Hi,when you say negative bus,is it the circular ring,with multiple male Lucar spades?

It may be worth confirming it's full connection with the vehicles ground.

A diagram or link to the system wiring you have,may assist.
