I will shortly have a field shelter, 12"x24" with an apex roof, for my two horses. Running mains electic to the shelter is not practical just at the moment, so I want to rig up a 12 volt system using the 85Ah leisure battery that I currently also use to power the electric fence.
I seem to recall having similar setup to this when I was a kid, so I think it works, but what I was planning was this: a) Purchase 2 car headlamps and fis them in the apex of the roof at each end, which should hopefully give sufficient light coverage. b) Utilise the sidelight and headlight circuits so I can control the lightling level. Maybe even the full beam for emergencies?! c) Use a car headlamp switch (one of the dial ones not an indicator stalk one!) to control the lights as this will also look quite groovy. Poss even a Vaux one so I can pull it for an external light outside the shelter?
Questions:
1) Are there any bits of the plan that are a bit blonde? 2) Does the -ve connection on the headlamp come back to the battery, or to ground, in which case do I also ground the -ve on the battery, and can I use the same earthing rod? 3) Are there any bits of the circuit I'm missing? No relays or anything for the switch? Do I really want to be fusing the circuits? 4) Do I need 12v wire or will 230v cabling do?TIA for any help!
