    So I recently ordered new fog lights because my old driver side fog light was not turning on and I have HID fog lights installed. When I was their taking them off I notice water on the oem plug and on the HID plug. Would I have to replace the wire of the fog light to get it to work?

    You have HIDs installed in your OEM fogs? If so please remove those and place them all in the trash, don't invest time in fixing it. HIDs in halogen assemblies cause dangerous levels of glare to oncoming drivers, they are a major safety hazard and illegal. This thread covers all the correct ways to run high performance fogs that have an SAE compliant pattern with optics specifically designed for LED, meaning no excessive glare to oncoming drivers.

    Fog does not glare to oncoming drivers, because the fog lights are glaring downwards to the pavement. And yes I’ve had HID’s on all me vehicles and never had an issue with them.

    Putting HIDs in your reflector halogen fogs is one of the most egregious and dangerous lighting mods possible, not to mention illegal. I realize you are new but you will not get support for such an inconsiderate mod here. It is a fact that HIDs in halogen reflectors causes levels of glare vastly over legal limits, they pose serious danger to oncoming drivers, and they do not produce the appropriate beam pattern. HIDs do not work the same way as halogens.

    Read this article by one of the worlds top automotive lighting experts as to why this does not work:

    Fog Lights can't create glare in the eyes of oncoming drivers. This means no part of the main beam can strike the body of a person, vehicle, screen or other object higher than the fog lamps centers 25 feet or more ahead. Fog lights, properly aimed, should not blind oncoming drivers. But they also should only be used for foggy conditions, and even then it doesn't seem as if they help much.

    i mean i can explain it more if need be I came here for help not criticizism nor arguments.

    If you read the referenced article you’d see that your assumption is incorrect. Halogen bulbs in halogen fogs work the way you describe, but because an HID arc does not replicate a halogen filament light source, it isn’t compatible with the optics that are specifically designed for the halogen filament. In short, while the beam pattern should be low with the fogs, it isn’t with HIDs in halogen housings and creates massive dangerous glare to oncoming drivers.

    But to answer your question, some water in the connector isn’t ideal but it should still work. Swap your bulbs from left to right, if the same side remains out it is likely your ballast has failed.

    Quite a few things at this point..
    LEDs don't shine light the same way as halogens, and thus need a different housing to control the way the light propagates. In the wrong housing LEDs become very blinding. It's pretty simple physics, easy to Google.

    Glare, in layman’s terms (relating to automotive lighting) is uncontrolled or mis-directed light directed at oncoming driver’s eyes. A good fog light – properly aimed – will have no glare because the flat, wide beam pattern does not send any light at oncoming driver’s eyes as you stated. Glare is undesirable and can even be dangerous.

    That said, a good fog light can have its beam pattern significantly altered by changing where the light source is. And that’s exactly what @crashnburn80 was referring to when he tried to school you on what happens when you put aftermarket HID bulbs in a housing designed for halogen light sources. The placement, size and orientation of the light source is a critical variable in light design. Get it wrong and bad things happen. Both HID and LED drop in aftermarket bulbs get it wrong.

    I will add a qualifier in that a fog light that depends on a fluted lens to correctly distribute light can somewhat overcome minor changes in the position of the light source. If your fog light relies on flutes in the reflector instead of the lens to properly distribute light, all bets are off.

    BTW, you stated that your fog lights aren’t very effective anyway. This could very well be because your HID bulbs with their incorrectly placed and oriented light source have messed up your beam pattern. Mike drop.
