Quad headlight upgrades?

[BigAlVB]

I have the quad headlight setup (with the cool grille) on my '91 Suburban. They are halogens and I have the relay kit that allows the high beams and low beams to be on at the same time.
Heck, I can't hardly see at night with the low beams and, of course, can't use the high/low combo all the time around town. Are there any kits out there to replace the stock headlights with something that has a replaceable bulb? Our Grand Prix GTP has Sylvania Silverstars and aftermarket driving lights and WOW, what a difference!
Please help. I wouldn't want to accidentally destroy my beautiful truck, and especially that grille , just because I can't see at night!
