THEY ARE from BIQU, they seem like nice units.no i did not use a resistor as i figured the led would light for a sec and blow if it got too much current

The problem is the LED may fuse and allow the driver to blow its output devices... Many semiconductor
devices failed shorted.  A series resistor to limit current is the most universally useful component
when debugging circuits.

Glad its working now.
