To quibble, you can’t pop a HID into a reflector housing at all, usually. Halogen and drop in replacement LED have a different focal point than HID bulbs do.
This means if switching to HIDs you also need to replace the entire housing so it will focus the light correctly. No amount of adjustment will be correct if the beam isn’t focused properly.
Also last time I checked most drop in LED bulbs aren’t really intended for on-road use.
The headlights in my wife’s old car were a real pain in the ass to replace, you either had to take practically the whole front bumper apart or grope around blind from the wheel well. I debated on getting her LED bulbs to hopefully never have to do that again, but I noticed that they were marked as something like “for off-road or motor sports use only”
