Hello Puneet, Contiuing what Ice-wise said,
1> Proper 4300K HID kit in Fog housing should work well. As IW said, they do work as second set of Low beams and are very helpful in spotting ditches, Speed breakers, Broken roads and stray animals.
Please check my XUV thunderbolt thread, i10 Blue Boy thread, Genuine 4300k AC HID kit review. You will see plenty of Pics at how the Beam pattern is preserved and there is no blinding effect. However, you WILL need to aim them a bit lower due to sheer power of these bulbs.
2> Opening the Fog housing is Invitation to trouble. If you have spare fogs lying, these could be a try. However you will need VERY small Projectors. Usually the lens size is not a problem, its the depth where you have to cut the back side of Fog housings to accomodate these. And thats where water/ Moisture seeps in. They're pretty low and prone to splashes.
Also, I do not know that the Projectors you have are FOG oriented. Search of Hella Micro DE. Low beam oriented pros won't work well due to step cutoff. Fog Projectors use a flat cutoff.
DO NOT remove glare shields and run them as high beams. Defeats all purpose.
3> The So called LED projectors available in market are a total mess. The beam pattern is useless and will do nothing but Blind Other people. Only decent LED fogs I respect are OEM ones with BMW X5 or X6. The price is close to 1 or 2 scooters though.
