Discovery 1 Head Lights flicker when the car gets wet

Hi everyone,
Got a 97 Discovery 1, it has HIDs on the headlights.
The issue im experiencing is everytime I wash the car, a few hours after the headlights start turning on the brights/high beam on and off by itself, even when the car is not being driven.
Does anyone have a circuit for the headlights so I can follow all the wiring and hopefully find a resolution to this.
Thanks in advance

On the D1 all the headlight current goes thru the in car stalk. I have only experienced having no headlights other than high beam / brights. I don't have the HID's you do and I drought you are washing the interior .

I also cant turn the vehicle off if the lights are still on in mine

97 300 tdi

Some may say be thankful for having headlights

HID headlamps are a non-standard addition therefore the LR circuit diagram won't be applicable, but u can start checking the additional HID kit that will be installed somewhere at the front near the headlamps I suspect.

Then as HID are not legal on a D1, so restore the headlamps back to factory and then u will find a wiring diagram in the D1 workshop manuals… Haynes or online.
