Fuses

I plan to fit some led lighting, in my bay, probably's under the dash and in the engine bay, I'm wiring them directly from the battery, via a toggle switch on the dash, what size of in-line fuse should I use for this ?

 

You will only need a small fuse, 5A will be fine

 

...also fuse lower than the rating of the cable.

 

Fuses, switch and l.e.d lighting now ordered, thanks !
