Anyone work with LED lights

Thanks all.

Trailbeast, I intend to go the same way but i have to get the car on the road first.

For the headlights, I am going old school with a set of Bosch lights that run h4s...and getting the headlight kit being sold on FABO.

At first I was going to use the two inner tail light section from a 2013 Mustang for my four lights, but HOLY CRAP they are pricey.
I would need four of them, and the average cost even used was hundreds each.
I used a modified bayonet bulb with magnifiers on the inside of the lense surfaces to spread the beam of the 9 LED bulb.
I would like something with more definition to the LED's like the Mustang lights but I'm not spending 800 bucks to do it.

That's why I had that calculator, to build my own.
LED's are cheap as hell, it's apparently the assy labor that gets ya and I can do that part myself.
