We've pretty well run through this LED topic but I'd like to add one last thought and it's not about LED brake lights.
When I first bought my 1981 R65, it needed some love. I spent quite a bit of time fixing, replacing, tuning and inspecting the entire bike. This post-buy work is always a good idea.
Upon removing the plastic tail light lens, I spotted a melted area adjacent the always 'on' tail light. The PO had fitted a larger 21 watt bulb and the generated heat had done a serious melt down on the expensive plastic lens.
The stock tail light bulb is a small 5 watt #67/97 that's about one-forth the physical size of the #1156. The larger, hotter bulb was in very close proximity to the plastic, hence the heat damage.
I run the SuperBright 1156 LEDs as tail lights in both R65s. They are much brighter than the OEM 5 watt-ers, plus there is no bulb-generated heat damaging the pricey plastic lens.
