the bulb I put in is a 4000 kelvin bulb and is direct H4 replacement......and that is actually a tad towards the yellower side of the kelvin spectrum than the whiter vehicle industry standard norm of 4500k kelvin...it does put out higher lumens using the same wattage as stock but the light it puts out is dispersed more out to the sides and farther in front of the bike rather than just simply being brighter..Unplug bulb and turn to release?? I can't see it being any harder then this but I have only glanced under there.
I am adamant in my opinion that the stock setup is far more superior to 98% of any other halogen setups I have seen. You guys have to realize that the yellowish light is actually better for night vision because it provides contrast, also brighter does not = better. Brighter light usually makes it even harder to see anything that's not directly in the path of your lights. It's like when you turn the lights off at night in your home. It takes a while to adjust to the dark, too bright of a headlight makes it so your eyes are useless to anything but the lighted up areas.
(How can that be anything but safer ?)
The position lights are purely cosmetic..they add no light to the road what so ever..the light color in them means absolutely nothing except for a way to get you more visibility from drivers in your front..in that case..brighter whiter light is exactly what you want instead of dull yellow light...im going amber because my denalis are super bright white and i run them at high during the daytime anyway
