flashing!!!

hi their
i noticed last night the indicators on my 200tdi discovery have gone a bit mad! the front and side are flashing like a perv, but i have nothing at the back, it also doesnt show up on my dash, but my trailer light comes on if i put my foot on the break, ive checked bulbs ect all ok, its geting a bit dodgy joining a motorway esp when you have a lorry up ya back side, so help is their a quick and easy answer to my flashing prob xx

if yer say yer bulbs are ok then yer probelly gort bad erff

how easy is it to find the bad earth, xx

depends how hard yer look. if ah have a bad erff problem ah usually clean up all the contacts in the rear lights and the ones where the erff is screwed onto the body. ah dint even bother wasting time looking fer it ah just do the lot. that way yer sure of having done it and it stops any more going in the next few weeks

thanks, ile give it a go, hopefully ile stop flashing soon!!!!
