While I don't know for a fact, I would guess that the Bentley is
wrong on this.  You would certainly not want to do a high-watt
headlight upgrade and have the current flowing through your stock
wiring and switch.  That *will* spell disaster.  Even if the
wiring or switch doesn't melt imeediately, there will be so much
voltage drop through them to completely diminish any advantage that
the new bulbs might provide.
