Modern Vespa

Hi Guys - bought these babies today

http://www.sportsbikeshop.co.uk/motorcycle_parts/content_prod/187453?r=GS&gclid=CP2Mu97InrsCFZHItAodMDMAiw

What is the best way to power them on the 500 - direct through to batteries or connected to some other areas like the live on headlight???

If I connect direct to batteries, where would be the best place to bring them out and leave out for connection?

I am sure some of you guys must have done it to perfection, would be great to pick your thoughts - did a quick search but couldnt find anything solid - if you know of a tutorial then please post the links.

Thanks

On my heated gloves, I used the glove mfr-supplied lighter plug and used the plug in the storage area. Didn't buy or install anything else, no fuss.

The wires snaked out of the storage into the handbrake lever and up the gloves.

Thanks guys.
