I think that would just widin the hot spot area.

If you look at the hot spot now it's just one area but if you use the wide spread I think it would make it a bigger hot spot area.

there would prolly still be a dark area around the 40 to 90mph area..

If you get what i'm trying to say

what if you painted the tip of the led that way you only get indirect lighting i'm guessing a lot of the hotspotting is from the tip ... i might play around with this
