Default 2007 WRX D/S Fog Lights Keep Burning Out

My driver's side for lights keep burning out after about a month of almost daily use. My passenger side works fine. When I go in to change the light out I unplug the first cable from the fog light housing and liquid will spill out. I'm assuming that this is my main problem. I'm unsure where the liquid is coming from as there is a splash guard under it and I even taped the bottom up to prevent water from getting kicked up by the tires. So I'm guessing it's coming in from above somewhere.

Is there a diagram or video showing the route of this cable so I can follow it and seal the cable housing, or try to replace the wire (most likely splice in a new one I guess)?

Thanks all.

Just order a replacement light assembly itís 12 yes old. Likely the housing or the seal to the lens has gone bad from heat cycles and impacts. Moisture builds up inside the lamp then thermal shocks the bulb. Unless you can find and re-seal the moisture intrusion ; this will happen over and over.

The moisture isn't getting into the housing, as far as I can tell. It's happening to the wire that connects to the outside of the housing. The housing acts as a bridge between the bulb wire and the wire that goes up into the car. The inside is fine. The wire that connects to the outside seems to be the problem.

Thereís the seal around the wire to the housing and the weather pack seal inside the connector. You can try and replace just the back cover if it still available. But likely youíll end up with the whole light. (Pic for illustration purposes only (not valid USDM part numbers))

So that 84931G*B is the back piece. On the back of that (not shown) is another connector for a wire that goes up into the engine bay area. The wire that connects to that (not shown) is where the moisture is occurring.

I forgot I made a video of it. Go to 3:20 to see what I mean (
