Do those LEDs work correctly with the H3 reflectors as far as directing the light down the road, rather than all over the place and blinding oncoming drivers? Some LEDs look bright, but don't actually work correctly with the stock housing reflectors and scatter light all over instead of correctly aiming.

 

That was the exact problem I had when I tried to LED bulbs in the stock reflector. They looked bright when looking at them, but not so bright looking down the road. Installed 7” LED adapters from Lased Design and the improvement is literally a day/night difference. Been running the LD 3D printed parts on and off road for 3 years and they have held up fine. Too bad the company is “a little” flakey.

 

LED bulbs have come a long way. I too was a skeptic, until I did the research and saw what the difference is between cheep old tech bulbs and the better improved technology. I thank wfturner for sheading some light on that. (Big old pun!!!)

You have to buy a model that places the LED emitters (more than one since our H13s are Hi/Lo beam) in the same position as the filament of a Halogen bulb AND avoid any LED model that has domed emitters. The flat emitters put the light directly at the angle the light from a filament would to use the OEM reflectors. Note the S-V4s above. Domed emitters spread it out and provide poor performance, too much splash on areas of the reflector that do not focus the light down the road. Also stay away from headlight bulbs with COB chips. Even though they are flat, their illuminating surface area is way too large and floods the reflector with too much light, all in the unfocused regions.

You also need to adjust the headlight aim after placing in an LED which is also why so many Clowns with cheap azzed LED replacements blind on coming traffic. I have had mine in for almost three years, never been flashed yet.

Are the OEM H3 reflector enclosures crappy? Yes. Can you put out much better light in a focused beam superior than any Super Duper Halogen? YES.

The problem is everybody and their cousin's brother jumped into the LED replacement bulb industry with crappy, poor designed cheap product to sell to the masses that do not even know how to adjust a headlight, let alone know what they are looking for. If a excellent proper functioning replacement LED is $75-$150, but you can buy a $30 model, we know what happens............ all the Clowns come out at night.

 

I just took pictures of the light output in my driveway at dusk,foggy night, and my driveway has a positive grade. Fogs front and rear and fogs with headlights front and rear. My 3 is pointing at the house across the road(approx 150ft away) and the light is weak drivers side(prevents blinding oncoming traffic) yet you can see the light beam drivers side points UP, not at the garage door pointed at,yet light beam show on the right. The oem enclosures work with these led's and I've never adjusted them:

fogs from the rear:

fogs+headlight from the rear:

fogs front at 60ft(note light beam ds upwards & ps down):

fogs & headlights front at 60ft(note light beam ds upwards & ps down):

 

Yea! Lol! I'm definitely a clown... haha. I have and had led headlights in the past and got rid of them. Trouble is I have to send $75-$150 to get a decent product but can spend less than $50-$75 and get a boat load of halogen products on fleeBay or Amazon market place. A lot of them come from Europe. Germany is very popular. So, NO ling long dingdong products.
