don't buy these. All you're going to do is blind other drivers without giving yourself better vision.
If you want to join the cool LED guys, buy a housing made for LED bulbs. LED bulbs in a housing made for halogen bulbs is crap

The shill is real. Also these are illegal for road use.

AFAIK there are no DOT approved LED halogen retrofits.
That makes them illegal, not that the cops seem to care but the other problem with this junk is the light distribution is terrible and they fail frequently. And they could cause damage to your vehicle for the favour.
In Japan, the hand can be used like a knife.
But this method doesn't work with a tomato...

It's cheaper to drive with your high beams on.

It doesn't matter that they are not DOT approved for halogen housings.

What really matters is that these 2 things make it completely useless.

1) Blinds other drivers (LEDS were NOT designed to go into halogen projector housings)
2) The light emitted actually reduces your OWN visiblity

NOBODY should buy these for halogen reflectors. if you want to do it right, retrofit with LED or HID *Projectors*. Still not dot approved, or technically legal but at the very least you are making it safer for yourself and others.

You can see these people from miles away when they put LEDS in, glare all over the place in your rear view mirror and substantially decreased useable light out front as they drive by.

Don’t think a stock projector is taking H4.

These H4 bulbs visibly have the same cup around the LED in the exact spot the cup is around a regular filament H4 bulb. The light pattern should be the same as an H4 Halogen bulb. Earlier versions of H4 bulbs did not have this cup so it was basically like driving with your high beams on all the time. These new versions have very similar beam patterns as Halogen H4.

I put LED H11 bulbs in my 2018 Civic factory projector housing and they work great. Beam cutoff is extremely sharp.

I skimmed your link and i am basically saying the same thing but in far fewer words. So if what i say doesn't matter then saying the same thing would not matter either so you and your link are wrong by your logic :rolleyes:
The point of being legal is that they have the correct beam pattern and don't blind oncoming drivers. At least your link has details. Not damaging your housings is also a nice benefit of using certified bulbs. Not to say all LEDs will but bad designs can have the heatsinks overlapping the install points. The housings are often rubber or plastic.

NB
I use them for the high beams and aux lights. They do give more light than the stock bulbs but WAY too much glare when used for low beams.
I AM NOT A BOOMER, but I wish i was.

If the light bulb you are replacing is used as a Daytime Running Light (but at a lower voltage), the LED bulb may very well cause you problems. Google is your friend.
