I installed driving lights on my 2010 street glide and now driving lights work but low beams will not work. I wadded 2nd acc switch so I could run driving lights on high if I wanted. So I ran the O/R wire from first acc switch to 2nd acc switch tgen spliced orange wire from that acc to driving lights. The driving lights go off with high beam but have no low beam at all?

 

Either one of your splices has a problem or your low beam filament just happened to quit at the same time as your mod. Use a volt meter to confirm power on the low beam connecter in the plug on the bulb. If that is hot, you need a new bulb. If the low beam connecter isn't powered, re-check all of your work related to the low beam power wire. I suppose there is a very slim chance the hi-low switch has failed on the low side, but more likely the bulb or one of your connections. Check for a plug behind the headlight not fully seated if you separated any of them while working.
