brake light fuse keep blowing

hi all my 15amp fuse keeps blowing after about 5 mins of driving. its got to be earthing against the metal somewhere just wondering if anyone has had the same problem and can tell me where in the harness they found the brake.
oh i have one bulb that's been blown for ages thanks all

weekest part = the rubber sleave that passes from the right rear wing to the rear door, the wires are single core and very briitle (if this is where the problem is then suggest replace/bridge all wires using flex cable as they're likely to all fail, I used cable stripped from an old iron)

do you mean it keeps blowing or you've just left it for ages :whistle:
if it keeps blowing then maybe that's where the problem is, can you see any fish swimming around in the light fixture.

Did you sort this as I had a very similar problem but found it was one of the other items on that fuse circuit. When I went in to reverse in fact; the sender was flattened and in the wet the current arced across. It only happened in the wet and when I used reverse but at first I blamed it on the indicators!! :silly:

its strange a fuse will last for about 20 min then pop a checked the lights there is no water in them will try turning on other lights if it causes a trip

That's exactly what I had and it was because the rain took a while to short out.
