Questions about those round LED headlights -
5-3/4" or 7"? Do they still allow your hood to go back on?
What model LED headlights did you use? Have you seen the Morimoto Super7 BiLED headlight sets?Not cheap at $500/pr, but are recommended by Headlight Revolution as brightest and most-focused units available. https://headlightrevolution.co…-super7-bi-led-headlight/. I've been wondering about trying to fit a set for additional lighting during night rides, but not sure I want to spend that much money as an experiment when I'm not sure how well they'd fit in generic 7" headlight buckets. Currently, I'm thinking about removing the center nose piece that seems to block the lower portion of the center Hella headlights on my 2015.
