Headlight problems - with video

Hi all,

Having problems again! (does it ever stop:doh

My 90 is due for it's MOT this week and I've only just had my indicator problem sorted, I've now found that my headlights are not working properly; getting a little bit fed up with it now...

Dimmed and normal work fine but when I switch to the high beam only the left side works and the right side switches off completely.
When I use the "flasher" (not sure what the proper name for it is, sorry) the left light works fine and the right one stays on Normal:

- Low/dimmed: works fine
- Normal: works fine
- High: Left works fine, Right does not work at all
- Flash: Left works fine, Right stays on Normal

I have also found that the interior light has stopped working, not sure if this is related though

I've made a quick video of it:

Any help would be much appreciated

Looks like live feeding back.
I would check all the earths and all the connectors.
Gonna be time consuming, but worth it.

more than likely an earth or a connection behind the headlight bowls,theese get adapted and alterd over the years and scotch lock connectors arnt un common

I found a nice mix of twisted together wires and parcel tape behind mine. Some people shouldn't be allowed to work on their vehicles!

Thanks guys, I'll take the headlight out tommorow; just hope its something simple.
Spent £190 last month on getting my indicators sorted; which turned out to be a something shorting behind the dash:frown:
Will update as soon as I know more.

It all looks absolutely, perfectly normal to me!

Your drivers side high beam is out, A because the bulb is knackered or B because there is a loose wire to the high feed.

When you use "flash", it momentarily switches on the high beam circuit, as it's just a quick flash, but the relay that controls the dipped beam also stays on. Thats normal. Then when you switch your full beams on, it switches OFF the dipped beam and switches on the high beam only.

In your case the high beam on the drivers side is out, hence why you never see it, but the passenger side behaves as it should!

A modification that is often made is people will rewire their headlight high beams so that they can burn both filaments at the same time, lamps don't last as long and you need to beef up the earth wire as it's not rated for the full continuous current.

Discomania...where is this relay? I have dipped beam only...no high beam...but my 'flash' works fine...so i reckon the relay is fubar.

Now I think about the control aspect of it there is no relay, it's all done from the switches - well it is on mine and according to the wiring diagram I have. My above post remains correct, only it should read, "When you use "flash", it momentarily switches on the high beam circuit, as it's just a quick flash, but the switch maintains the dipped beam circuit."

If you only have dipped or flash, then take a look at the contacts on your dip/high switch. When you pull it towards you it simply makes contact for the high beam to come on too, when you push it away it disconnects the dipped beam and connects only the high.

Look at the switch, the contacts can get dirty and or the metal fatigues and doesn't push up against the terminal hard enough.

Hmm..have looked there...will try again and see if i can avoid setting fire to it.

Why don't you fit a new bulb in the right headlight?

Looks like the main beam filament is broken.

Put relays in to protect headlamp dipswitch[if thats what you call them over the pond] chees

look in Q's and A's section for wiring diagram.

a quick solution would be to run a wire from one headlight over to the other, as long as the single feed to one head light will take the amps for both

WHY? Nothing is broken! And the wiring wouldn't cope, it is only rated to 7.5A, 120W @ 12v = 10amps.

His drivers side high beam is out, A because the bulb is knackered or B because there is a loose wire to the high feed.

Fixed now!
Took both the lights of and reconnected them again

Glad it turned out to be an easy one for once.

Thanks for the replies all!
