Wow, I had no idea you could make one of these yourself. You have some pretty easy-to-follow instructions on here too. I've been considering starting up a tow truck business. I would definitely need a lot of these lights for that. I could probably save a lot of money if I could make them or find them at a cheap dealer. The light you have on this post isn't exactly what I need, but there are some on this site that are similar to what I need: <a href='http://www.ledqusa.com' > http://www.ledqusa.com</a> Is it possible to make lights like this?

Hi Rahib you can draw power from "Disconnect CFL connection" point as i marked in my circuit diagram

You mean directly, from the positive pin of battery?
