P45t adapter with LED headlight
The adapters are well made and fit nicely in the housing.
To make sure I didn't go off all half-cocked and make unnecessary modifications - I taped the LED bulb to the back of the housing and mounted it to the headlight bucket - it fits without any drama. So the issue is either with the P45t adapters (plastic bits), the H4 adapters for the LED bulbs or the metal bulb caps. I've looked at the assembly a few times and believe it's either the H4 adapters (tangs are too long) or the P45t adapters (plastic interference with metal bulb cap).
Follow up EDIT: After some additional monkeying around - it turns out that both the P45t adapter and the LED bulb adapter require modification. The LED bulb modification requires that the tangs are near flush with the P45t adapter (and they're still good to go in the H4 housings after modification) and the P45t adapters have to be shaved a bit with an razor blade to allow the cap to interlock with the housing. I did get one to fit. If I get time later this week - I'll get the other one done and test them out.
I'll call this a draw until I get a little further into it.
