can reccomend fitting relays to the headlight high and low
beam . vast improvement on light output the easiest way is fit two
new fuses and cut in the relays at the headstock if you are doing
the other wiring upgrade, then fit a new three or fourway fuse
holder and splice off the battery cable to supply the new fuses
then run new cables to headlight via the relays. dont forget to
run a new earth as well. you may need to replace the exsisting
headlight connector with a new one to accommodate the new
wires as i did.
