Included Parts:

Step 1: Insert the bulb into the main headlight unit, and secure using the plastic collar. 

Step 2: Use the 4 included short screws, secure the plastic side lamp holder onto the metal bracket. Pay attention to install the holder onto the correct side (as shown in picture)

Step 3: Install the side marker light onto the plastic holder. 

Step 4: Insert, using moderate force, the 3 bigger plastic nuts into the rounded sockets of the metal bumper. The plastic nuts should click into place. Please pay close attention to the side of the metal bracket where the plastic nuts are inserted. 

Step 5: Insert the long screws first, then sleeve the small plastic insert along the long screws onto the main headlight unit. Use moderate force to clip the 3 plastic inserts into the rounded holes of the main headlight unit. 

Step 6: Using the long screws, screw the main headlight unit to the metal mounting bracket. The long screws act as adjusters that can be used to adjust the lighting angle of the headlight.
