how much does it cost to replace the headlght

dont but a headlight, just dis-assemble it take you bulbs out and you can drain it

not more than ten dollars.. get the bulb out and find the model number. make sure the inside is totally dry first. be sure to put/twist it in using a towel/glove or something; finger residue can wreck the bulb because of high heat in operation.. this is for a modern car.. 70s and 80s cars have a sealed headlight.. different.
