Installed a mtn fit hood on my 9 last year and installed some aftermarket headlights from walmart in the hood. i wired them to the stock wiring and noticed my volt meter on my gauge dropped to about half maybe a little below, my gauge backlighting is also dimmer and the headlights are so-so. they are bright but not to the fullest as when I hooked them up dirrectly to a battery. Do some night riding here in mn and can see but not that great lol any thoughts or input? Should I install a relay or ?
