38 coupe,
Good point, as to the adjusting the beam. You are right, the LED's don't have the same pattern. I did that shot in the bay the car is parked in, with the cardboard set up against my work bench and was about 2' away.
Thought I would post a few more pictures taken at the same time showing before and after, with the old period correct sealed beam lights and the new LED's. The first one is against the garage doors, a bit further away. The second one is again with the cardboard leaning against my work bench. Up close, the difference in the pattern is very obvious, but in actual use, the LED's make a world of difference when you are actually driving.
It took me 3 years before I was able to actually able to see what they did on the highway (I had to get up early, before sun rise, to go to a show, the local club was putting on) I did notice I was able to see and read the traffic signs on the side of the road, unlike before. Like most of us I don't drive the 53' Merc at night.
Heck, for that matter, I never drive anything at night!
I think the video really shows the difference. For me it was a matter of seeing the road or not. Driving at night with the old stock bulbs was just too dangerous.
As they come out with better 6 volt pos ground LED bulbs, I can always swap them out in a few minutes.
