I noticed the pattern difference on the garage wall. I’ve been waffling between the sealed beams and the Koitos. They don’t take long to swap out, so I might try different bulbs with them to see what the beam patterns and brightness look like.

Check out the second to last picture at this link - https://japanesenostalgiccar.com/hella-7-halogen-h4-conversion-headlamp/ -- it's a comparison of the beam pattern/cutoff from sealed beams vs h4 halogens. With the H4s, all of my light is focused on/across the road ahead, while with sealed halogens the light is limited to smaller/discreet "blobs." Magic came for me once I followed H4 headlight aiming instructions -- switching to brighter bulbs didn't hurt.
