headlight housings for a 2004 Honda Odyssey for $80. I'm not sure what make your 20 year old van is, but I checked a few other 2004 vans. A pair of headlights for a Caravan is $62. A pair of headlight housings for a '04 Ford Freestar is $60.50. Nissan Quest headlights are the most expensive of the bunch. You can get new ones for $160 for the pair, or you can buy OEM used ones on E-Bay for $100. Toyota Sienna headlights are higher than the others, but not as high as Nissan's. They're around $130 for a pair of new replacements (or $100 for used OEMs on Ebay).
