Get conversion headlights. Any of my sealed-beam lights get replaced with Hella E-code conversion lights. Get Hella E-code. yes, it matters. They put the light where it belongs, so you get the most out of your bulbs.
They use a removeable H4 (halogen) bulb and plug into your factory harness. They look close enough to original that they don't look out of place; the beam spread is MUCH better than the sealed beam stuff; and they're about 3x brighter than the sealed beams.
I also add HID H4 bulbs from ddmtuning.com to any of mine - they come with their own harnesses, easy to install, mount the small ballast somewhere, and enjoy the view. I run 4300k color temperature - it's the closest you can get to daylight, without turning blue (higher numbers are more blue; the human eye is least sensitive to blue light, so blue lights are the least effective for visibility), or yellow (lower numbers are more yellow; if you have a lot of fog in your area, go more towards the yellows to cut through it - I run 3000k lamps in my fog lights on my 2001 Ram and 2500k in the fogs on my 2014 Grand Cherokee).
You can get hi/lo H4s from DDM, as well as hi-only, depending on which location you're using them in (if you have a quad-headlight car). The HIDs are about 3x brighter than the halogens, so compared to stock sealed beams...the stockers will look like candles. The Hella lights are metal reflector/glass lens, so I run 55w HID's in them. My 2001 Ram 2500 has factory "Sport" package lights with plastic lens/plastic reflectors, so I run 35w hi/lo HIDs and 35w LED high-beams in it to keep from overheating and distorting the housings.
And, car-off? The Hella H4s are basically invisible. Looks like stock. At a car show, nobody will ask "why did they change those lights?" - because unless they're REALLY nit-picking...they won't even notice. I'm ordering a set for my '70 Charger as part of the list for this winter...once my budget recovers from buying the car itself (and my Grand Cherokee is paid off in January, so that frees up a good bit of monthly dough)!
