“Great product my only suggestion would be to inform customers that when switching from low to high beam then the low beam turns off and only runs the high and if you also offered a $20 relay to allow both low and high to be on when the switch is in high would be great. I had a single bulb in my last dual head light (not quad) and so when changing to this set up it reminded me a 90s chevy pickup. Lol. Plug and play for a dual set up sure but should state that info and or show it in the pictures (new trucks both stay on in high). I almost sent them back and went with the projector headlights and that required a $30 relay and pigtail until I found the relay that I needed to allow both to be on. So give the information and suggest the relay or better yet, have an identical option with the relays alreay installed and, 5 starts all day. Great product though I did upgrade both sets of bulbs that it came with and dang.”
