Some very informative comments about "DOT Approval" and "SAE Approval" for automotive lighting:

http://www.candlepowerforums.com/vb/show...-and-fog-lights

Quote:
The issue at hand is "approval". What I was pointing out to the OP is that "DOT approved" and "SAE approved" don't mean anything on any lamp, and "DOT" on a fog lamp doesn't mean anything.

SAE is not a regulatory body and has no means or authority to approve anything. SAE just issues technical standards, supposedly representing the best practices in whatever the standard is about (fog lamps, turn signals, headlamps, etc). These technical standards do not have any force of law, except to whatever degree a political entity adopts them. The Federal Motor Vehicle Safety Standards incorporate some (but not all) provisions of some (but not all) SAE technical standards for vehicle lights, and while SAE standards are updated periodically, every four to six years, these updates are not automatically acknowledged by NHTSA, the agency within the federal Department of Transportation responsible for the Federal safety standards. If you read the Federal lighting standard, you'll find it contains numerous references to very old versions of SAE standards, going far back into the '60s. That's a shame, but those are the provisions that have the force of law.

There is no such thing as "DOT approval". NHTSA and DOT are not legally empowered or authorized to approve vehicle equipment; that's not how the American system works. Instead, the responsibility lies completely with the maker or importer of the equipment. The "DOT" marking on a headlamp does not mean DOT or anyone else has approved it, it means the manufacturer or importer has decided the headlamp meets all the legal requirements. "DOT" on the lens is the maker/importer's own assertion, or certification, that the headlamp complies with the law. There is no particular pre-test required; lamps do not have to be sent in to the DOT or anyone else before the marking can be applied -- the maker does whatever they feel is necessary to satisfy themself that the lamp meets the standard. Reputable companies put their lamps through rigorous tests. Shady companies laugh and put "DOT" on the lens, gambling (often a winning bet) that their lamps will never be checked out formally. If an investigation is carried out and a headlamp marked "DOT" is found to be noncompliant, NHTSA can force the maker/importer to issue a recall and can issue penalties in the form of fines. Very steep fines, assessed on a per-violation basis, with each sold headlamp counting as one violation. But these enforcement actions are rare, and even when they do happen, the target is often a slimeball "company" consisting of not much more than a warehouse for unloading and stocking containerloads of pretend-headlamps from China, and a marketing department to promote them. Get smacked with penalties? Declare bankruptcy, disappear for a week, open up shop under a new name, continue business as usual.

You'll notice I've been talking about headlamps for the last paragraph or two. That's because headlamps are the only lamps required by law to have a "DOT" marking, and therefore the only lamps on which "DOT" actually means anything. There's nothing stopping anyone from marking other lamps "DOT", but it means whatever the maker decides it means, which could be anything from "It means this lamp meets the applicable provisions of Federal Motor Vehicle Safety Standard 108 as they appeared in the official legal text as of the date the design was locked in for production" all the way to "It stands for Dogs Over Tampa".

You'll frequently see "SAE" followed by letter/number codes, followed by a 2-digit year code, on many vehicle lamps. These markings aren't legally required, but they're allowed, and they mean that the maker says the lamp meets the requirements put forth for [whatever function codes are present] as of [whatever year is listed]. For example, you might find "SAE AI6RSTP2 97" on a multifunction taillamp. There's a breakout chart of the SAE codes on this page which explains what all those codes would mean. But it still doesn't mean or imply anything about anyone's approval.

Fog lamps are not regulated Federally, so states are free to regulate them however they wish, from no regulation at all clear on up to no fog lamps at all (not allowed to be used in that state). Front fog lamps can be marked "SAE F [year]" or "SAE F3 [year]" -- there is no legal requirement for any such marking, though some states say you can only have fog lamps with an SAE marking.

As you can see, it's more complicated than it seems on its face, and the lighting aftermarket's many scam artists are safely betting that most people will think "DOT Approved" or "SAE Approved" or "SAE/DOT Approved" is some kind of a meaningful assurance.

This is why I encourage people to buy aftermarket lamps from a reputable, North American company. As the above points out, there are little to no consequences for someone in an offshore plant who produces lights with fraudulent "SAE" stamping and sells them on e-bay.

As for whether SAE/DOT means anything in law, it does here.

fsdork, it does mean something up here, but only in a peripheral fashion. You put in garbage "Dot Certified" assemblies and law enforcement finds them problematic, you get the ticket. wink

So I guess I'm just being a whiner when I complain about people driving around at night with neon green headlight bulbs? Just last night I saw this [censored] little 80s jeep with spidered out wheels and the idiot put neon green angel eye type LED surrounds on the headlights and was only using those for night time illumination.

There's lots of lifted bro trucks around here that have a similar setup where you'd think they were sponsored by Monster Energy or something.
