2 x35 watt at 12 volts equals = 5.83 amps. They are less than the halogen bulbs draw but they still draw a fair amount.
The bikes battery is 12 amps with the alternator putting out 18 amps at 5,000 rpm.
At tickover during periods of high load you will always see some voltage drop.
At tickover during darkness waiting to turn right the electrical draw would be as follows,
Indicators 21w x2 + 3w = 45w (3.75 amps)
Tail 5 w x 2 = 10w (0.83 amps)
Brake lamps 2 x 21w = 42w (3.5 amps)
2 x 35w = 70w (5.83 amps)
Instrument panel lamps 3 x 2w = 6w (0.5 amps)
Ignition circuit including fuel pump at a guess around 10 amps (correct me if I'm wrong but it's protected by a 20 amp fuse)
A conservative estimate of 24.3 amps. I would guess that at tickover the alternator puts out around 10 amps, add to that the 12 amp battery and you're on the limits of what is available.
The system was wired in perfectly and worked without a problem for three years. The mate I sold it to had no problems with it either.

Never underestimate the ingenuity of an idiot!
