This is true. However, it is also true that even if your lights are perfect in all aspects, they are still illegal if you made them yourself.
Quite right.
I don't have the know-how to make my own automatic leveling system (yet?).
You could always cheat and buy the ready-made Hella retrofit auto-levelling system, then all you'd have to do is adapt its actuators to fit your headlamps.
I don't think most people understand all the work that went into these
I think you're right!
I could show pictures and comparisons and cite all sorts of safety standards, but if it ever came down to it, they would never pass as legal. No retrofit will.
Yup. That goes with the territory of most of the lighting regulations in the world. Whether we're talking about a brake light reg, a headlamp reg, a bulb reg, whatever, all of them allow some bad lamps and prohibit some good lamps. It's a matter of practicality, really -- at some point you have to pick where to draw the line in the sand, and just hope it gets the job mostly done, pretty well, most of the time. And that's just thinking about OE lighting! It gets a lot harder to regulate aftermarket lighting. Much of it is junk to one degree or another. And it's even harder still to regulate lighting modifications (homemade lights). You obviously put in the time, money, and effort to really
understand the technical and legal requirements and make lamps that come as close as possible to meeting them, but I feel very confident saying 999 out of 1000 people don't. The only regulation that makes sense, given that reality, is "No homemade headlights". The few who know/care enough to make safe and effective modifications and keep a careful eye on them to make sure they remain safe and effective, probably aren't going to get caught.
Scheinwerfermann, do you have HID lighting in your car?
One of 'em is factory HID, but not my present daily driver. I don't have occasion to drive it fast or far enough at night to miss them; when your night drives rarely exceed 30 mph, you never get to use high beam and there are always bright street lights around, the advantage shrinks in a hurry.
I can't believe I've not seen you around hidplanet.com
Ohhhhh, you might've without realizing it! ;-) I have had a screen name or two on there over the years, though you're right, it's quite awhile since I ducked in. Herman & co. still running it?
the place prides itself in trying to convert people who want HID kits
Yup. I remember for awhile Rich Van Iderstine (who was in charge of FMVSS 108 for 25 years or so) was on there as "Mr. 108", and sometimes the fireworks were amusing to watch as ignorant knowitalls would try to
argue with him about what the regulation says and means (that's the regulation he wrote...what a hoot!)
Oh, and btw, my setup is FX35 projectors that comprise high and low beams in one projector, so as long as I aim my low-beams correctly, my high beams are in the right spot.
Yep...that's a good way of getting around the relative-aim problem if you have the space in the housings. And if you happen to be lucky enough to be working with a headlamp from which the (halogen) projector can easily be removed out the back without having to break any seals or cut anything, and there's an HID projector from the same maker with the same mount points, that's easiest of all! Doesn't happen as often as would be nice, but it does occasionally happen.
