As usual, it’s not as simple as the lumens output. Certainly the HID on my car give me far better night vision than the halogens on my van! And the latest LED fitted to some cars appear to be even better. So a decent, high quality compact LED replacement for the RS is my holy grail. I do a fair bit of riding in the dark on secondary unlit road, but I really don’t want to hang some horrible side bars and expensive wind breaks to the side of my RS if I can avoid it.
