To each there own, but if you are involved in an auto accident that your vehicle lighting comes into scrutiny don't think for a minute that you will have any insurance coverage for it:
However, when it comes to the lights that work as your main forward illumination in the U.S., they must remain as fitted from the factory be it sealed beam, HID, or replaceable halogen bulbs in a housing. If your car came fitted with LEDs from the manufacturer, then, and only then, are they legal.
Aftermarket LED Lights
Yes, LED replacements are available via the aftermarket. Installing them is technically modifying your headlights and not allowed by national law through FMVSS. Yes, you only changed the bulb, but the headlamp no longer conforms to factory—i.e. legal—specs.. The reflector and lens of American vehicles' headlights are designed to work with those halogens, which is why using an LED replacement bulb is both illegal and typically results in crappier lighting than the OEM units.
Before you suggest changing over to an OEM LED housing, that's potentially illegal as well. If it doesn't have DOT or SAE markings on the part, that would also be considered an illegal modification according to FMVSS. However, it's also federally illegal to swap an LS7 into your Mazda MX-5 but federal law really hasn't stopped that from happening. Sort of.

OEM LEDs In The US
LED lights are not illegal, except where the headlight is concerned. You may use LEDs in unregulated auxiliary lights. Side markers are A-OK. Brake lights? You'll potentially blind the driver behind you, but they are legal. Fog lights are also fine, as are those super-bright LED off-road lights you installed on your mall crawler.However, when it comes to the lights that work as your main forward illumination in the U.S., they must remain as fitted from the factory be it sealed beam, HID, or replaceable halogen bulbs in a housing.

LED bulbs are now much more common in cars, including brake lights, fog lights, and interior lights. LED headlights are increasing in popularity, too. However, the legality of these bulbs can be questionable.The general rule is if you have a halogen bulb currently installed and you want to upgrade to LED, it won't be road legal. It's classed as a kind of headlight modification, as you're switching halogen technology to LED technology.
In theory, LED headlights are a great idea. However, because of their issues, it's difficult to find LED headlights that are safe and road legal.

As of 2/2022, LED headlight bulbs are not legal modifications for cars registered for on-road/street usage.
"In the United States, lamps, reflective devices, and associated equipment are regulated by the US Department of Transportation (DOT). Even though these types of LED lights can be used in place of an original halogen light bulb, it is not legal to use on vehicles registered for on-street use. This type of modification can only be done when used in a fog lamp application, dedicated off-road application, or in jurisdiction outside the USA where this is allowed. For more information on how to determine if this typeof product is safe to use, and legal to use on public roadways in the USA, Click Here for a more detailed breakdown of compliance."

I agree with conanski that the proper light will work ok.
But, in my experience, the LEDs dont seem to keep their original brightness long. I had a set of Lasfits and for the first month and a half they worked fantastic. But after that they seemed to only be mildly better than factory low beams. Maybe i got a faulty set or cheap set. But the Hella halogens i have now seem just fine.
