It was enough of a projection of gravel so that the "Mini" is one-eyed. Like many models, the glass is sealed on the reflective parabola which forces to change the whole optical block. An operation accessible to all handyman, but it must proceed with method.

Replace a lighthouse optic

Practical advice

Make sure that the locating pin of the base of the main bulb is lodged in the notch of the reflector. This avoids mounting the bulb upside down. Do not touch it with your fingers, especially if it is a halogen bulb. Otherwise, clean with alcohol.
● This replacement mode is applicable to other makes of cars, the basic principles remain the same.

The optical block has a chrome reflector whose bottom is open to receive the base of the main bulb (high beam and cross), which is held by a spring clip (or circlip) wedged behind three pins. Located just below, a second smaller hole lets the pilot light (4 W). The block is mounted between a chrome strapping (placed at the front) and a metal shell with two notches (at the back). The whole thing is tightened by three Parker screws.
● You can order a brand new dealership for a brand new dealership, or recover it in a "breakage" as it is the case here: it is in excellent condition. If you choose new, you will need to keep the strapping and the shell. In the second case, you will probably leave with a complete set.
● The block is housed in a plastic bowl with a large flange, riveted to the bodywork. Two special screws mounted on this flange are used to adjust the light beam. It is also on them that are placed the notches of the shell, held in position by a large coil spring.

What to do

Start by removing the chrome trim. Retained at the top by a lug and fixed at the bottom by a Parker screw, it is pulled forward. Without touching the two adjusting screws, release the notches from the shell by rotating it. Be careful not to hurt yourself with the pieces of glass (wearing protective gloves is not useless). Pulling slightly, the block is detached from the bowl but is still solicited by the large coil spring. Using a pair of long nose pliers behind the headlight, detach the spring that is moored to the shell.
● Once the block has been released, remove the spring clip holding the holder of the large bulb and remove it. Then pull the bushing of the night light, the defective block is then completely separated from its environment. It remains to replace it by proceeding in the opposite direction of disassembly. Normally, if care has been taken not to touch the two focus screws, adjustment of the light beams is not required.

Unscrew the Parker screw

Unscrew the Parker screw

The broken lighthouse glass is all the optics that must be changed. Start by unscrewing the Parker screw that holds the hubcap in the lower part, then tilt it forwards.

Clear the indentations

Clear the indentations

Print the block with a rotational movement so as to clear the notches in the shell of the two screw heads of the bowl. One is at the top, the other at 90° to the left.

Detach the coil spring

Detach the coil spring

At the top of the reflector, we distinguish the notch released from his screw head. With long nose pliers, loosen the ends of the coil spring connecting the shell to the bowl.

Remove shell and base

Remove shell and base

The back of the lighthouse shows the shell and the base of the main bulb. To remove the latter, first remove the spring clip which secures it to its support.

Take out the night light

Take out the night light

Located under the main bulb, the pilot goes through a hole lined with a rubber ring. Its support being claws, just pull on it to take it out.

Install the recovery block

Install the recovery block

The recovery block, pre-equipped, can be installed. Reconnect the base of the bulb and the pilot and then, with the pliers, hang up the end loop of the spring on the shell.

Upper and lower screws

Upper and lower screws

Each headlight has two adjustment screws. One (upper) is used to focus the beam in the vertical plane, the other (left) to adjust in the horizontal plane.

Fit the hubcap

Fit the hubcap

The chrome trim covers the whole. In the upper part, hook its rib to a lug provided for this purpose and center it on the strapping, also chrome, of the headlight block.

Replace the Parker screw

To complete this reassembly, it remains to replace the lower mounting screw of the hubcap. Before setting off again, check your headlamp settings one last time.
