How does this work? Plug and play shift light

[dickieandjulie]

Hi Guys and Girls

I wonder if anyone here can help? I have previously considered getting shoft lights but wondered about fitting. After today at Brands I definitely feel these could be beneficial and saw these on Demon Tweeks:

'Plug & Play shift lights'

My question is - how do they work? Surely they must have a lead that picks up the pulse from the HT lead like a timing light?

Hope you can help
