Keith, I run a very similar set up but reverted to Halogen bulbs in the spots after the LEDs began to disintegrate internally (vibration??). I also have a heated vest.

I find if I connect the vest along with everything else that it is just too much for the alternator, turn off the spots and there is more than enough capacity for the vest. I have a 35w HID dipped beam fitted so tend not to use the spots so much as there is plenty of light coming off the front of the bike already.

One thing I have noticed is that if battery voltage begins to drop the orange EMS light begins to flicker on before it drops too much - time to turn something off. There is usually still enough juice to start the engine again providing the engine is warm.

I love my heated vest this time of year, good investment.

Cheers.
