unscrew the two plastic nuts with the 10mm wrench

remove the fire by pulling back the inner part

clean the body part

put the fire in place by passing its two threaded rods into the locations of the bodywork (it's very simple, no chance of making a mistake)

hold the fire with one hand and reconnect the ground and the fire plug with the other hand

check that all bulbs are working before continuing

tighten the two nuts securing the light with the 10mm wrench

position light

flashing

stop

reversing light

fog light

We have the right light plate but this diagram is not necessary. We can visually inspect the filament of each bulb. A broken filament is usually very visible.

Avoid touching the bulbs with your fingers. It is best to wear gloves to avoid leaving greasy marks on the glass.

press the bulb lightly

and turn 1/4 turn counterclockwise

remove the bulb

Not all tail light bulbs are the same. Any defective bulb will be replaced with an absolutely identical bulb.

insert the bulb with its lugs in the housings of the plate

press lightly

and turn 1/4 turn clockwise

reconnect the board alone, by inserting the plug (you should hear a "click") and the ground wire

turn on the ignition and test all bulbs

Once you know that everything works, turn off the ignition and unplug the board

Place the plate on the fire and press it to lock the 5 clips

check that the 5 clips are properly locked

replace the foam seal, remembering to fold down the lower part
