After reading a bunch of threads about what LOOKS best, I have to ask what WORKS best. Now I'm not talking about brighter, I mean better. This might be common knowledge but the lines on the glass (even the curvature of the lens) of the sealed beams focus the light into a usable beam. I've seen lots of model A halogen conversions that at night emits a large, bright flood beam.....NOT a focused beam (on low beam) and older kits that need to be used on high beam because the flood pattern is so wide it defuses the light. I like the look of big original lights, but I also drive a lot at night. So I have a few questions. The sealed beam conversion and all 7" aftermarket headlights are lumped together because the output is the same, the only difference is ascetics. With only one to ask a question about. -What about the sealed beam conversion BEHIND the stock glass, anyone used one?. I would assume that it would suffer the same or similar issues because it still has to shine through the stock glass. I also have a question about the stock lights with halogen (or led) conversions. -I see that the later headlights ('32 and up) have a decent setup of lines on a curved glass. How do these compare to sealed beams (again light beam vs flood) and that includes '34 commercials. Basically I want to know if there's a stock light that can be as good (beam wise) as a sealed beam or do I suck it up and use the Guide lights I have on my '28.
