Because I don't ride at night I never thought about installing LED headlights, that is until I rode the Blue Ridge Parkway in Sep. and the first tunnel I went through I wasn't sure if my lights were even on. So, I now have have LED Headlights. Having said that, I have the Arc LED Daytime Running Light / Fog Light kit from another vendor and since installing the LED headlights, they now work a little different. Now, both the DRL and fog lights work with the head lights on dim. Only the fog lights work with the headlights on bright. Strange but that's how mine are working now. I guess that's what happens when you combine two different aftermarket products. Knowing what I know now, I would still buy the LED headlights.
