Continuing the story, since I now have an H4 setup, I removed the Halogen H4 bulb and replaced it with an inexpensive H4 LED that I already had. It’s advertised as being much brighter and clear light than Halogen. It’s definitely a much whiter light (different light temperatures, or colors are available), and possibly illuminates a little further down the road, but only on low beam. On high beam, the halogen does a much better job of lighting up further down the road. Looking at the bulbs, I suspect this has to do with the design of the elements inside the bulb. Maybe a more expensive LED would do a better job on High beam, but I’m thinking I might just put the halogen back in. It does a significantly better job than the original sealed beam light at both low and high beam, and when I turn on high beam, I like halgen’s performance better than the LED.
