Pass. Front Headlamp (low beam) won't work

[dukbludvl]

Hi all - I installed the R&D headlight and foglight controllers yesterday and noticed today that my right front low beam headlight won't work. It's not the bulb b/c I tried installing a new one and that didn't work, adn I put the old bulb on the left side and it still works.  Does anyone have any idea what might be wrong and how I can fix it?  Do I have a short somewhere?

 

The weird thing is that it worked fine after I did the two R&D controller installs yesterday. This morning when I turned the Yukon on I noticed my battery was running high at 16v instead of the normal 13.5-14.7 range.  It returned to normal after driving a while throughout the day.

 

Any suggestions would be really helpful. Thanks!
