How does this work? Plug and play shift light
Discussion
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

It works by picking up the very small oscillations in frequency from the charging circuit output diodes. Variations in alternator speed due to pulley sizes varying are cancelled by the adjustments on the control box, you set the lights to come on as you want them to.
Well thats what I reckon, and if someone else says otherwise then one of us is wrong.

Yes, they definitely work off the alternator ripple, that's why they also work on diesels, I used to sell loads of these, and never had any probs or comebacks. If anyone wants one I could be persuaded to get some more, and they'll be a lot cheaper than the price cited... chris@chriswilson.tv
