I tried searching and could not find much info.

I have a silvia front end on my S13 and am wondering if there is a DOT Approved headlight I can use(aftermarket or whatever) or if there is a way I can fab something up so it will be DOT/SAE approved.

Thanks in advance

JDM silvia head lights are NOT DOT approved....they were never in the U.S. and never recieved DOT approval, plus the cut-off is designed for rhd so mostly u will blind oncomming drivers.....there are write ups on how to modify using differnt projectors......most places that do inspection wont care of even notice....

I'll tell you right now. You won't find much info because most people don't know. Good for you for trying though.

First, let me explain to you how the process works. I got slapped before so I'll try to be gentle.

The USDOT does not approve anything. The USDOT publishes a series of specification. Maufacturers self-certify that their product complies with DOT specifications.

If a manufacturer's product doesn't comply and the manufacturer self-certify anyway, if the DOT finds out the product gets yanked and the manufacturer gets a fine.

It's like the honor system with severe penalties if you get caught.


Second, any exterior light that has "DOT" or "SAE" stamped on the lens has been self-certified by the manufactured as DOT-compliant.

Check your lens. If you have the stamp on all your lights, you're good to go.

If you do not have the stamping, you have to find something that does. Otherwise, it's not legal.

The best way is to look at the part itself. And remember. Just because they self-certify doesn't mean the light is compliant. I remember a bunch of aftermarket Civic headlights getting recalled and the manufacturer got a huge fine.


The best way is to stay with US-spec lights. Some Euro/JDM lights also have DOT/SAE stampings. I remember my new S13 Silvia corner lights from Courtesy having DOT/SAE written on the lens.

I think another problem is the height. The silvia headlights are too low to the ground, which is why that front end was never sold here.

Headlight beam adjustment generally falls under state jurisdiction, although most states defer to DOT specs for beam pattern requirements.

I was referring to Federal Motor Vehicle Safety Standards, Sec. 571.108 Standard No. 108; Lamps, reflective devices, and associated equipment:

Table IV - Location of Required Equipment
FMVSS


I think the center of the Silvia front end's headlamps are below 22 inches, therefore they were never DOT legal and even if you found housings stamped with the DOT, they would not be up to standard due to the height restrictions. Unless, of course, you put a lift kit on your s13.

There are also standards for cutoff in the above section.
