97 Ranger Fog Lights Keep Burning Up

[97Ranger3.0]

On my 97 with fog lights, this thing burns up the H3 bulbs like crazy. I'm wondering if this is a common/known issue and expected, or if it's because I have aftermarket fog light housings. When I bought my truck, the glass housings were busted so I bought a pair off ebay. It seems like water is getting in the housings or something, because they are super rusty inside even though they're not that old. It's frustrating though, because I rarely use my fog lights but when I need them it seems like one or both of them won't work, I replace the bulbs and it's good until I need them again lol. Again, is this just a known issue? Or should I spend the money on some better housings?

I've replaced a few factory fog lights... they take a beating down there. I'm sure mine were when driving the freeway. Seems I've replaced a few bulbs too... but I used mine pretty much all the time.

With the temp a halogen bulb reaches, any water will likely shatter them instantly. I would try led bulbs, just because they don't have a filament to break. But yes i would definitely fix the water issue first...

You making sure to not touch the bulb on install?

Are the H3 bulbs you're using 55W or 100W?

I have had great experiences with H3 bulbs in housing that's are well sealed from outside forces.

I am on my third set of OEM fogs. I have never had to replace a bulb until the glass would crack or break. What bulbs are you using. I have found Silverstars to have a very short life in headlights, and also in the H3 versions. However, their quality control is good as they will burn out within 2-3 days of each other. They (and any blue tinted bulbs) are not worth it in my mind. Those lamps are too small for 100W bulbs. They will make the lens too hot to touch and might cause a heat crack if hit by icy water. Small lights for 100W bulbs usually are far better built.

The OEM fogs are not the best sealed lights. I found that running a bead of free flowing, penetrating silicon sealer around the seam where the glass lens meets the metal reflector goes a long way. One of my fogs lost a lensed due to moisture compromising the bond. Also, I have found even a brand new set can have a badly placed bulb sealing boot. In fact, one off-brand 'replacement' did not even have boots. I have kept all the old lamps for spare parts. BTW, Ford Mustang fogs from the same period interchange, but you need to splice in the Ranger plug from the old light.
