LED blinker troubles

I installed a Wipac LED light set yesterday. Today I installed the flasher and if I select left or right they all blink. I removed the bulb in the dash which solved the problem but now I have no blinker indication. Anybody have a fix for this?
 
Dave, I converted to the TD5 gauges and warning lamps. There are separate left and right blinker indicators on the newer setup. It separates the left and right circuits completely.

Not always. I am running that exact flasher in my current setup. Still flashes all the indicators if the bulb is in the dash.

I do like Adam's fix. I might swap to that one of these days.

Not to say that LR's don't have ground issues, ( and that is in fact the culprit for a myriad of problems on them)but that is not why all the lights flash, and if that fixed yours it likely means you just provided a better voltage drain due to some other voltage leak of which a Rover harness has plenty.

The stock wiring relies on the opposite indicator (signal) filaments to provide the ground for the flashers (the bulbs on the right side ground the left, and vice versa.) LEDs don't provide as much resistance as incandescents, so enough voltage gets through the dash indicator bulb to light the opposite side indicators.

This will happen on nearly every motorcycle you put LEDs on and it is the exact same principle. Single dash indicator allows voltage to flow both directions, thus lighting all LEDs due to the small amount of power required to operate them.

Trust Moss Motors to make a video. That is a very easy understand explanation of what is happening.

I have bought a boatload of parts from those guys, if you have other British heaps, they are a handy company to know.

Two load resistors at the front blinkers and I'm back to normal.
Thanks all,l! We are an awesome, knowledgeable, helpful community.

Will these work to solve this issue? I was told they were to stop a fast blink, but that isn't my issue. The issue is both indicators blinking with only one side selected. If so should I install these on all for indicators or just the front or back? I have the RDX LED indicators, not the WIPAC incase it makes any difference.

Whiule we are currently on this subject, will trailer wiring still work if you are running LED signal lamps?
