I am answering Kevin in NJ comments below which are in the bold letters below;
What is not brought out is where the light goes. It gets glossed over.
I dunno where the light goes Kevin, ...the light probably evaporates into space somewhere.
Seriously, is this the "right question" you think we should all be asking ourselves??
The point to focusing the lamp is to put the light where it needs to go and not into the trees or the eyes of the oncoming cars.
Again, more misinformation. 'Aiming' and 'Focusing' are two different terms, -and you are confusing the two. 'Focusing' deals with making a crisp beam whereas 'Aiming' deals with keeping the light beam(s) out of the trees or oncoming traffic's eyes. Since an incandescent bulb only has one or maybe two filaments, the light of the filament is focused using the parabolic shape of the reflector to produce the furthest beam as possible with just that thin line of illumination. Focusing an LED bulb that has many diodes emitting in different locations is not necessary to concentrate a beam of light in a direction. The intensity of the diode(s) is what determines the distance and pattern.
A while ago someone did tests with a light measuring device and found the halogen solution did put almost the same amount of light where you need it to drive. But it also put a lot of light all over the place.
This all can be argued until Jesus comes back, but the bottom line is people need to trust people who have actually used them for their feedback, -and quit listening to people who have not even tried them. To prove my point, tell us all where you purchased your bulbs, and how long you tested them on your own car. My experience counters the opinions you are giving.
Pretty sure blinding oncoming traffic or be in the mirror of the car in front is (not??) a good thing.
This poor comment has been beat to death also. I am pretty sure I can blind oncoming motorists and/or motorists in front of me with an improperly aimed Model-A headlamp, -no matter whether it has an incandescent bulb or a halogen bulb. With that being the case, not sure how relevant it is to using an LED bulb when any bulb can be made to blind oncoming traffic or illuminate trees.
So a real test would be measuring the light in multiple places. I am pretty sure there are standards for light amounts in areas in front of the car.
I doubt you would like to compare a 32cp bulb with an original reflector in a modern DOT test where specifications are set for LED and Halogen lighting. Secondly, the "real test" is when someone here reports their findings when they have installed LED bulbs in their own Model-A.
Do these LED lamps meet these requirements when used in the A headlamps? We do not know and likely will never know. If you are going to ask the questions you need to ask the right questions.
Again, this same comment has been 'over-used' and it never gains any traction. Here are the truthful facts regarding this, ...most naysayers of the LED bulbs have never even used them, however they are full of opinions based on hearsay. Most people that have reported favorable results on this site and social media are people who HAVE used them and found them to be an improvement.
As I recall the original type bulb with a good reflector and properly focused did a decent job lighting the road. A direct fit halogen did better. Both work fine with factory electrics.
This I will partially agree with. The only thing is you left out one sentence. You should have added; 'Certain direct-fit LED bulbs have been found to produce more usable light than the incandescent and the retrofitted halogen bulbs.'. The LED bulbs have also been found to work fine with factory electrics.
The bottom-line in this entire thread is people should only give feedback on subjects they have first-hand knowledge of, -and not an answer based on hearsay, opinions, or possibilities.
