Little problem with the headlights, side lights work, full beam works, dipped headlights don't.

Going to look at it tonight but thought we could have a game of guess the fault and I'll let you all know what the issue is.

I'm going with either the headlights are low on oil or it's upset that I briefly looked at a jeep that was next to us at the lights.

(No serious guesses we all know it's either an earth or the switch has failed)

Failure to use the dip, not much point anyway. No one will flash you even if you remain on high with series sealed beams.

Headlight upgrade on mine to halogens but if it had sealed beams i wouldn't bother using dipped at all - id just put a couple of candles on the front

Bulbs?
I have had two go at the same time although they were sealed beams, no relevance really.

That is one of the things I will check, although I went in the garage today and one of the tyres was flat so knowing land rover if your bulb goes it probably deflates one of the tyres as well
 
If you swap the bullet connectors over for main and dipped that will tell you if bulbs gone but both is unlikely so check you have 12v on the positive feed before they split to both , maybe just need the connectors cleaning / remaking

I think its most likely the switch as the main beam on both is working

same bulb but they have two filaments and 3 terminals as in pic

a cheap multimeter is useful when tracing voltage

So a "fun" evening with the multimeter playing why the **** aren't the dipped beam working.

It's either just upset because the other day the Mrs was in the landy and said it's noisy, smelly, slow and there's much better rides out there (it shouldn't be upset, she was talking about me)

Or
There's a break in the wire somewhere between the switch and the point it branches off to the headlights, bulbs are fine, switch is fine. No damage to the bits of wire I can see and no damage to the loom. Everything else is working fine.

So I have 2 choices rip open the loom to find the break, or just run a new wire from switch to the point it branches to the headlights 😔
 
Won’t it be the bullet connector near the radiator?

Usually is.

It’ll either be hanging under the rad panel or stung across the top of it between the lights.
 
Just realised I didn't check the stalk, the wire for dipped goes to the stalk first doesn't it, then to the headlights, so the most likely place for a problem is there.
