Any advise on Sapph rear lights issues 😞 (rainbow effect)
The problem is the rear lights go funny if I have the indicator on side lights and press the brakes they sort of dim between each other I have today cut the rear plugs off and attached them with separate little plugs and soldered it all in and added an extra earth from the body on each light and has made no difference also if I press the brakes and the handbrake is on the light on the dash dims too as well as the other dash lights this also happens if I turn the indicator on any warning lights on dash slightly dim anyone had this issue and managed to resolve it ? Are there any earths on the rear before I start tripping it all out
I have also today taken the speedo out and cleaned all the earths behind it and found an Earth on the passenger side footwell cleaned that too.
Any help much appreciated
Regards
Tony

Too many posts.. I need a life!!
I've only ever know it to be bad connections or bad earth on the rear lights themselves.
I remember years ago have this problem on a mk3 escort and no matter how much a cleaned up the connections it wouldn't cure it. I fitted new 'bulb holders'?? And soldered in new plug connectors and it was all fine

If you take your side carpet out and follow the wiring loom back. There is some joins in the loom. I had a problem with one of my reverse lights and i cut one of these joins out to fix it.

I have noticed if I use the hazard lights instead there is no rainbow effect at all and everything works perfect ! But if I use one indicator only say left or right then I get the rainbow madness ! Looks like I was using the correct wire for earth too

I have stripped loads of loom out of my pug and I have noticed a LOT of the ford wires are corroded a long way back in the loom, I suspect you have the same. It is the copper corroding I expect. Best solution may be to pull the interior and get an auto elec to replace the rear of the loom?
