I have a full size 1993 chevy blazer with sealed beam headlights, high and low beams are totally separate. So I have 4 headlights total. Does anyone make a aftermarket package for this?

Daniel Stern is pretty knowledgeable about lighting http://www.danielsternlighting.com/ Your car uses 9005 and 9006 bulbs. There is an upgrade called H1R and H2R or 9011 and 9012. They are expensive but seem to make a huge improvement and on this forum it has been discussed. http://www.candlepowerforums.com/vb/showthread.php?313028-H11- and-9005-upgrade These guys don't advocate using an HID kit because the light filament may not be located in the correct position for you stock headlamp housing to work properly.
