BCDrums, did you have any experience with the old Daytime Red? I'm curious how that compares with the new D6. I have the old Daytime Red, and consider it the best red tail light out there, by far. I also have the Daytime Yellow, but don't use it much anymore, although it is very effective also. My original batteries are about shot, so I contacted DiNotti to see if my old charger would work with the newer batteries. He said yes, but recommended the new D6 red tail light. I would consider it if it was anywhere near as bright as the old DT Red. But as I said before, nothing compares to that light. I would be hard for me to switch. Thank you.
