When my headlamps are on the front and rear off side indicators glow constantly and stay like that even if I indicate right, the dash tell tale also glows constantly. Near side indicators work normally. With headlamps on the offside sidelight also goes dim.
If I switch the headlights off the off side front side light goes bright again and the off side indicators will work correctly.
I suspect it may be the earth to the off side front headlamp but before I delve in (lots of stuff to remove to get at) would appreciate confirmation as to my thinking.

Even though I completely rebuilt her it was 17 yrs ago and I forget where the headlamp earth's are

Sounds like feedback down the earth side, you're gonna have to find those erfs ...

As a above, a typical symptom of an iffy electrical earth, fortunately you will only have to to check the light & indicator earthing points.

As I thought, cheers.
Still haven't had a chance to look at her yet except for a quick look and I couldn't see any earth points looking down at the light bowl.
Would it be easier to remove the headlamp and bowl to get better Access I wonder..?

bad earth on headlights causing the electrical pixies to back-feed through the indicator earth, path of least resistance.

Wouldn't happen with LED,

The earths for all the front lights are on the steel inner arch, around the top corner, right at the front.

if you have a length of wire, connect it direct to the battery neg, turn the lights on so the fault is present, then touch the wire onto each earth point. You should see that one, or more, earth points cause the fault to get better, or disappear completely.

When I done my rebuild, I ran separate earth wires from the bulkhead earth point to each of the front earths, to make sure this problem never happened again.

What happens with just the side lights on?

You can never have too many erfs on a Landy ...

Same, rear indicator glows all the time even without moving the stalk, moving the stalk to indicate right and nothing happens, just glows. Front off side side light also glows when sidelights or headlamps are on. Indicators act normally when no lights are on.
Rear and front pics. Rear indicator glowing.

and dull front sidelight and glowy indicator.

Had a quick look today and I can't see them using a torch but I've got lots of stuff blocking a clear view, block heater, leccy fan gubbins etc. I should get a better chance to look at the weekend hopefully. Probably gonna take the headlamps out and maybe upgrade the headlamp bulbs while I'm at it.

If your gonna do it proper like upgrade the wiring ...

@The Mad Hat Man has a great fred - help file for this ...

I've already upgraded wiring with relays same time as the rebuild 16 yrs ago. Just posted on general with a bulb query cos search don't work.

Oh yeah! Complete dismantle and refurb of everything. New chassis bulkhead steering suspension brakes everything. Suppose after 16 years things will start to play up again.

It's a Landy, it doesn't know any different ...

One of the holes in this photo is the original location of the earth screw. I can’t remember exactly which one it is though.

This photo shows the concept of how I made the new earths. Two repair washers, one ring terminal, and a nyloc nut. The earths on the loom just go over the threaded portion, and are clamped on with a couple of washers and another nut. Simples.

(if you zoom in on this photo, you may be able to make out the marks from the original earth location, directly above the new earth bolt).

Nice to see that you are replacing with Stainless fittings
