Jack,

I was doing some simple adding in my head when I came up with the 30A number=
.  The unfused standard headlamps are about 4-5 amps each, the parking lamps=
 are probably another 2-3 amps.  I know from personal experience that you ca=
n safely replace the British 35A fuses with American 15A fuses and they don'=
t blow.

Maybe a better way to go would be to fuse the unfused circuits.

Rick
