So I just received these $38 specials today.... https://smile.amazon.com/gp/product/B01 ... UTF8&psc=1
Don't even consider it....
The 'Garage Door Pattern' is all over the place. No matter how I tried to 'clock' these things they would not create a Low Beam Cut-Off pattern.
I have the amazon return label printed. They are going back tomorrow. I spent about 5 minutes of fiddling with one.
It's important to leave one side stock for comparison during the trial period.
As you can see the LED element itself is so big (compared to a filament) there can't be a focal point on the H13 headlight reflectors.
You can see they try with staggered element placement the way an H13 bulb's filaments are. Both sides come on with High Beam too! , but no cigar.
I think
H13 are such a unique bulb and reflector combo that it is starting to look like high power incandescents may be the only option for more lumens.
I think EldRitch is right.
edit:
So, just to get started,, I ordered one. Less than half a 2 pack: https://smile.amazon.com/gp/product/B005KDO8BY/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
