MIDNIGHT: I'm following that thread as well as the amp upgrade thread. Two mods that I am considering making that are important to me. I had LED's on my last bike and I had no problem riding at night. I am not happy with the set up for the RG, never was and it's the only single fault I dislike between it and the batwing. If you end up trying something before me, please post it and i will do the same.
When I was at the Maggie Valley GTG last fall, I noticed that Randy's (Otis is his handle on here) RG had HID's. I didn't get a chance to ask him about them (I think we had both had too much "Berry Juice" at night), but somebody told me he was selling them...you might try PM'ing him. Randy is a good guy and will help you out if he can. His were a bit blue, but that's just the bulbs...anything over 6K is too blue for my tastes.
Another great source of information would be Jim (hddude). I am 100% confident he would know what product to recommend, and he will give you a discount. The BEST HD tech (does not work for HD), period. I've bought several things from him over the years, and most of the California crowd here use Jim for ALL their wrenching. I have so much confidence in him that if I ever wanted serious motor work done on my bike, I'd probably ship it to him and let him do the work, then fly out and ride home.
As nice as the LED's would be, I have a hard time coughing up $600+ for some lights, even though it is probably the best long term solution.
