Finished headlight mods: HID + De-Amber + LED turn signals, city lights & fog lights

[ohhh my]

I would never recommend using LED's for headlight or fog lights, unless they were specifically designed and research for the application.

Believe it or not, the factory filament halogen light bulb and housing had many hours of research go into it. The point of the filament where the light is produced is strategically placed in a certain spot inside of the fog light housing, so when it illuminates, it perfectly reflects off of the reflector providing light in front of the car and a clean cut off line.

When you replace it with an LED, it's nothing more than a circuit board with a bunch of LED's placed on there with no calculations or consideration on which direction these LED's are pointing. So when you turn on these LED's they're just shining everywhere, in most cases, just lighting up the housing and producing no usable light on the road because very little of the light is correctly hitting the reflector inside the housing to project the light forward.

This same thing applies to people trying to use HID kits inside a halogen housing. The filament(where the light is produced) inside a halogen light bulb is a different location(further back) than where a HID bulb produces light. The difference is just a few millimeters which is why you get decent light on the road, but there is a lot of glare because of these few millimeters...

Yes, and no. The "fog lights" are just not practical where most of us live. For most, they end up being a cosmetic look. And the OEM bulb just doesn't match HID lights. The LEDs look better. As a functioning light, they are worthless.
