I actually did this just last night. It is somewhat complicated to explain, yet easy to do. The headlight assembly is well secured, that's for sure. I failed to take pictures, so I will do my best to put it all in words. The bumper cover will need to be removed to gain access. To start there are plastic trim fasteners that expand when the plastic screw is driven into them (Like what you would use in sheetrock). There are 3ea in each fender-well that attach in the forward portion securing the bumper cover. Remove these by backing out the screw and pulling out the stud. If the screws do not come out, you can use a flat prying tool of sorts to pull them thru the layers. There are 2ea tricky ones that are between the bumper cover and the fender. The easiest way to get them out is to slip a flat prying tool between the fender and the bumper. Now for the bottom of the bumper cover. There are 2ea more of the plastic fasteners under the lower portion of the grill of the bumper cover that will also need removal. Next are a series of 10MM bolts that will need to be removed from the under side of the bumper. If I recall correctly there are 9ea of them to be removed. Now for the top of the cover, there are 2ea 10 MM bolts to be removed. The bumper cover should be ready for removal. It is best to have some one aid so that the cover does not fall and get scuffed. Slide the cover FWD from each side, there are receptors that they fit into. If you have fog lights and an air temp gauge, they will need to be unplugged after the cover is pulled away. Now you have access to the light assembly. On the headlight assembly there is a bolt and a nut on the top that get removed, a bolt on the side of the fender and a bolt almost directly below the main bean portion (recessed a little). To put it all back together is relatively simple now that you know what makes it tick. Hope that this helps!

To change headlight in a 1994 Mazda 121, undo the top mounting screw. Slide a flat screwdriver behind the assembly abd pop out the fitting. Repeat with the other side to pop the other bayonet fitting and remove the old headlight.
Open hood and remove the hard plastic cover over the headlight and radiator; this will expose most of the mounting screws. Then remove the corner lamp by removing the retaining screw at the top corner of the headlamp; this will expose the remaining mounting screws.

Open the hood and look at the headlight assembly. There are three 10mm bolts holding it it. Remove these and unplug its wiring harness. Now you can remove the assembly from the car . On the back you will see three circular covers for the lamps. Unscrew these & replace lamps & reassemble! Hope this helps!
