bad grounds and you need to relay your lights.
If you take a meter and measure the voltage at the light pins you will usually find between 11, and 11.3V
After relaying you will see 13.75.

They make kits on ebay that are good and fairly cheap.
don't pay over 20 bucks and make sure the headlight sockets are ceramic.

What do Divorces, Great Coffee, and Car Electrics all have in common?

They all start with GOOD Grounds.

Where are my DIY Links?

I've used the relay kits on several mk1 and mk2s and can confirm they definitely helped. Couple of hours to fit and you're good!

I have, make sure it is all inclusive as a water proof fuse holder and relays (there should be 2) one for the high and low.

Here I did a search of the uk ebay.

This is one that I've used before:

I also ordered a cheaper one at around £11 in May 2020 but that listing doesn't exist anymore. Seemed similar.

Couple of sketchy photos below:

First shows how I installed relays in a 1990 mk2. I added the zip ties because I was concerned the relays might jump out. Probably unfounded. At bottom right see a purple-ish bent bracket that I made to hang the relays from slam panel. Not waterproofed, still working after ~1year.

Second shows same thing in my 1989 mk1 cab. I used some metal strapping to make the bracket. No zip ties or waterproofing and working fine after ~3years.

I could have done a neater job especially with the cable routing etc but it is how it is :D
