I have the 9003 sealed-beam replacements as well - the type with the crystal-clear lens (no fluting) and the facetted reflector, but I have not installed them yet.
I honestly have not gotten to drive the truck yet. Soon, hopefully. I have driven enough older vehicles with sealed-beam lights, however, to know that those bulbs are absolute $#!+... Especially with old wiring causing electrical resistance and making the already dim bulbs dimmer.
Sorry,
@DoubleDingo, but I will be using the obnoxious LED plug-and-play 9003 bulbs.
My part of Texas thinks streetlights and sidewalks are of the Devil. I'd rather irritate another driver for a few seconds than hit a pedestrian walking on the side of the street.
The bulbs I use are only 10k lumens (about 5000 apiece) though - less than many new cars with factory LED or HID lights - and I actually take the time to properly aim my lights to minimize dazzling. While 10k lumen is about 5x brighter than halogen bulbs, it's more the pure white 5000K color I'm after than anything. The warm 3000K of halogen bulbs absolutely disappear in heavy rain to the point that I might as well not have my headlights on at all. Not a good place to be in poor weather. The bright blue 8000K+ bulbs are equally as bad, and in my opinion, because they are
BLUE, they should be an impoundable level of illegal. However, light color in the 5000-6500K range is the perfect color to cut through the rain and light up road signs and reflectors down-range.
