I was always skeptical about these LED bulbs, however yours look promising. I know all the eBay china specials are no good, and the first runs of these types of bulbs (pre-projector lens on the front) were horrible for output. They APPEARED to be bright but did nothing in terms of lighting up the road/usable light!

 

LEDs in the fogs really don't give you much on road lighting.Stock halogen bulb's 1400 lumens will produce more road lighting.LED fogs 600-1200 total.Aftermarket high power bulbs around 2K lumens.
LEDs are great for aesthetics.That's why I have a pair installed.Matches the HID very nicely.
If you want more road lighting,you must go HID fogs.
