I have a 2006 F250 KR and after I installed my Z1 it seems that my headlights are not near as bright as they were before. anyone had this happen or know what it might be?

Thanks

I have to admit...that would make me nervous. Just to be sure, I would completely disconnect the Z1...including the reverse wire...and check your lights again. I wouldn't use "seat of the pants" determination...use a volt meter.
