Only if the LED isn't created properly. I have dropped in LED bulbs in tons of cars\trucks with no problems. Sometimes there is a second module you need (should be included) but most of the time there isn't.You can’t just switch to LED you have to enable LED via AlphaOBD or TazerDT. There are different setting to enable LED depending on bulb location.
Illegal?Yes, there are downsides (crazy glare, illegal - even if people do it all the time).
This is from Virginia but references a national standard (under the notes section):There are no downsides but also sometimes not upsides.
You will get a betters color light but it might be angled incorrect or not throw as far despite being a clearer light.

You can adjust the volt reading to LED so it doesn't throw an error if you just put in an LED not designed to be in-place of a halogen bulb.
Illegal?
Please provide proof that simply replacing halogen headlights with LED break the law
That's insane.This is from Virginia but references a national standard (under the notes section):

H7 refers to mounting socket of the bulb to fit the reflector. Sure, H7 LED bulb will fit in a H7 reflector, the only thing will be the focal point will be off. Look at the pic.That's insane.
What could the reasoning even be?
Section 6 says
Approved headlamp bulbs: HB1, HB2, HB3, HB3A, HB4, HB4A, HB5, H1, H3, H7, H8, H8B, H9, H9B, H9C, H11, H11B, H11C, H13, H13C, H15, HIR1, HIR2, H18, H19
You can buy an LED bulb that is marked as "H7" so therefore it's an approved bulb imo.

Dangerous glare to oncoming drivers resulting from the use of bulbs not specifically designed and tested for the contours of a given housing. Brighter isn’t better if light isn’t focused correctly, so small variations matter, especially when LEDs have very different light spread from halogen bulbs.That's insane.

I know H7 is the fit.H7 refers to mounting socket of the bulb to fit the reflector. Sure, H7 LED bulb will fit in a H7 reflector, the only thing will be the focal point will be off. Look at the pic.
If you move the red rectangle, Filament or LED forward or backward, you change your focal point. Light pattern will be different.

Even people with halogen bulbs can easily blind oncoming traffic if using the wrong style\size\not aligned properly.Dangerous glare to oncoming drivers resulting from the use of bulbs not specifically designed and tested for the contours of a given housing.

Don’t get me wrong…I appreciate the LED projectors in my Longhorn! But I’ve also been in many “I can’t see the road” situations with oncoming light glare. It’s much worse with a crazy bright LED bulb than with a misaligned halogen bulb.
Agree with all of that.Misaligned halogens are as bad as mis aligned LED's but technically on an LED bulb depending on where the chips are it can change the beam pattern in a reflector housing. LED's seem worse because we are more sensitive to blueish light than soft yellow light. Regardless I say run what you want no one is going to stop you and people will do it anyway. I have run HIDs/LEDs in refelctor housings in every older truck I had I liked them much better than the halogens. I never cared what others thought. Technically LEDs or HIDs in halogen housings are illegal, but so many people have them and thats the least of a cops worries now a days.
I agree it wouldn't be worth the time to prove. Blueish white or white is good but like you said, green or purple or red yes. Like the Ford super dutys for example they have LED's and the housings for them, are they still bright? Absolutley lolAgree with all of that.
I don't think a cop can even do anything, would need to be on your states inspection.
A cop has no way to know what kind of light a housing should or shouldn't have and they know it would never hold up in court.
Maybe if you got like purple LEDs and threw them in sure, but anything whiteish
