headlight switch
 

Does anyone know wether or not the headlight assembly from the 95-99 eclipse/talon will bolt up without making mods to the 95-99 sebring coupe?

It's essentially the same car, so the chances are very good it will work. On the other hand, if your lights are getting yellow and dull, you might try polishing up the lenses first. A kit will run you a lot less than replacing the lights. Be prepared to apply elbow grease.
