Its still reflector and lens adapters for modern form factor LED lamps OR, stuff from Cree or more anonymous asiatic fabricators in the 5.75" N006 or N001 form. I've washed my mind of any plans to install LED headlamps after seeing how manufacturers have pandered to piggery, making DANGEROUSLY OVERBRIGHT lamps exceeding the dangerously high current Federal limit of 2513 lumens per lamp. 800 lumens is MORE than adequate for lighting the roadway before one at night. HELL! We used to cringe and put on sunglasses when HALOGEN lamps first spread around in the late 1970s. I admit not all eyes are so photosensitive as mine, even 40 years later, but this whole ugly business of weaponizing automotive headlamps illustrates the terminal psychopathology of latter day consumerist capitalism brilliantly.
I use NOS 400x bulbs I scored several years ago for the C body rides, and will stick with conservative lamps for the recently acquired 1983 D150 Dodge Ram Miser. While I LOVE LED lamps for reducing the current load on the aging wiring and charging system, AND the superior light, I refuse to be party to blinding people on the road at night with headlamps. If I must resort to light weapons, there are cheap lasers available....
