Agreed...that's the best first step. But even the LED programming could not solve the plate light issue for me.Just my 2 pennies worth.
I too fitted the Club S indicators with side mounted licence plate/light. I had to fit the resister's that came with them as my bike came as standard with normal bulbs in the indicators.
I then found after adding the resisters there was way too much wire to make a neat and tidy job under the rear seat.
I decided it would be much easier and neater if I just took the bike to the dealers and asked them to change the cambus to run LEDS and get rid of the resisters once and for all. I knew it would cost a bit more money but did it and really pleased I did.
