Dash light issue

[gavL]

Sure someone will point me in the right direction

Got a problem when I put my full beams on the lights on my dash all go out. Tried a new light switch to see if its that, if I pull the stalk only a bit back so it doesn't click and the full beam comes on the lights do not go out though.

Any ideas on what it is?


Cheers

Poor earth or faulty switch

After the initial googling its coming down to I've either missed a Fuse or a Dodgy Earth. Will report back when i crack it, but if anyone wants to put something forward to test please do

This sounds a bit like what was happening 2 me a couple of years back, When i put lights on everything would go off, And then i found it was the original dimming wire that is fitted 2 the original stereo that wasnt being used anymore but was earthing out somewhere behind dash, 
Unfortunately i found out when it nearly burnt all my loom out, Smoke coming from underneath dash, Pitch black at nite and 15 miles from home, Had 2 drive home with no lites on and sh7t scared my car was gonna set on fire,
