Just recieved a Slot.it Sauber C9. Thought I would at least set it up ready for the In car Pro lights. So headlights, one or two LED's each side? What is the recieved wisdom, one LED caus you can't tell or two to look good. How do you mount them drill out the "glass" completly and just hot melt in the LED? Would the board take the load of 4 LED headlights. Thanks in advance.
