Let me start by saying I think the stock headlight is decent, but the lumens power of halogen lights only goes so far. LEDs are far superior and will also save you wattage should you want to add battery draining items. For example, I replaced the 55 watt H7 low beam with a 25 watt H7 LED light with 3x the lumens.
I bought the H7 plus and H9 plus kit from advmonster
. They're not super cheap, but this was after trying cheaper sets on AMZ first. At least at this point in writing the kits available either have heat-sinks too large to fit in the H7 enclosure with the seal on or have fans (which can go out) with no where to vent the hot air.
1. Wanted to be seen and see more as it's getting darker earlier. 2. Wanted to free up wattage to run more heated gear, possible fog lights. 3. Looks more premium
: You'll need to actually remove the gauge cluster, front fairings, etc. to get to the H7 (lowbeam) bulb. It's kind of ridiculous you can't change a bulb without doing all of this, but then again how often do you need to do it?
: DO NOT UNSCREW THE H7 RETAINING CLIP. I removed mine and had a bear of an issue figuring out an alternative. If you can't get the heatsink (rectangle box) in, John at ADVMonster recommended using an extended seal cap found on AMZ here:
The H9 (highbeam) is easy, just twist off. I also opted to replace the parking 5w bulb with a 2w LED to match.
: If you do everything right it'll probably only take you 1-2 hours max. If you lose the clip, drop something in the headlight, etc. you'll need to take the headlight off which will take you longer. However it goes for you, it's a worthwhile upgrade for sure. I think I remember reading from the amazing Greywolf that by lowering the running wattage drain on the bike more heat will be put into the charging system (stator, etc.) which might shorten its lifespan. Not sure if it's applicable with our bikes, but just FYI of a possible con.
