it is normal for the lights to get brighter with rpm due to the increase in voltage by the charging system. at idle, however, the bike is running only on the battery. how dim is it? if it seems very dim, it could be a battery issue. you can check this by taking a standing or idling voltage reading (this would be good time to take a charging reading also). take a voltage reading at the light socket itself too. if your readings are low, have the battery tested. if there is a significant difference between the battery and socket, look for bad wire or connector. if it tests all good, try replacing the bulb to see if that helps. dont forget to check resistance across the bulb adapter too. other than that, it must be normal.

oh wow, I thought I was the only that experienced this. I guess it's a pretty common thing and some members are even saying its normal. I was concerned about my headlights because I have 2003 R6 projectors in the F4i housing. Everything works great except for the dimming when I rev the engine. I also have Tacho/Odo problems. My tacho wont pick up any reading and will remain a 0. But I think this is a totally different problem. Maybe ECU or Ignition Pulse Sensor?
