I put Hella H4 lights into my cars and trucks from the 70s that had the old style sealed beams. H4 was an upgrade at the time from the crap that was available back then. My 63 BMW uses head lamps that use H4 bulbs. H4 bulbs do not have the sealing rings and can let in dirt, dust and debris, I would look for bulbs that drop in and work like 9007s. Watts and candle power is what counts, shop for that. |

VooDooMan, I sympathize with you... I have the IPFs in my TJ, and wanted to try to match the KJ... best I found was a "Nighthawk" bulb via Amazon. Bright, clear, but not quite as much candlepower as the IPFs. And by comparison, when I had an "emergency" replacement dropping in a Silverstar bulb on one side of the TJ, it was still not as bright brand new as the 3 year old IPF on the other side. |

well, I think the route I'm going is thus. I found an IPF housing that accepts H4s that is the same size as the KJ housing (and is aimable  ).
then all I have to do Is get some H4 sockets and cut apart my wiring harness. |

The Carello retrofit headlights I got for my Challenger had a large rubber cup/boot that sealed against the back of the headlight housing and around the three prongs of the H4 bulb. I put dielectric grease at both locations. No problems with air/water/dirt infiltration. Of course I wasn't offroading the Challenger, and the headlights only got underwater once (no water got in though). The Hella retrofit units also had a rubber boot. Perhaps those boots can be located separately if H4 units end up being used. |
