Forked Bracket Installation With Visor Clip
1. Insert one of the carriage bolts through one of the washers. Please note that washer is
used as a spacer on the square neck of the carriage bolt. Slide the bolt and washer
through the back of the right bracket.
For the 274-ULB21-U1, be sure to select
the correct bracket. The flange with a
single slot should be located towards the
center of the light.
2. Remove three of the #8 x 1/2" self-tapping Phillips pan head screws
from the left side of the light. Using the #8 washers enclosed and
assemble as shown to the left.
CAUTION: Take extreme caution not to over tighten the screws!!!
3. Install one of the forked “L” brackets onto the attaching bracket,
using the carriage bolt, a washer, and a serrated nut. Leave the nut
slightly loose to allow for minor adjustments during the remainder of the
installation.
CAUTION: Take extreme caution not to over tighten the screws!!!
Over tightening of the screws can strip the holes.
4. For the 274-ULB21-U1, repeat steps 1-3 for the right
attaching bracket .
5. Locate the two visor clips on the vehicle.
The style may vary from vehicle to vehicle.
Some styles use only one screw each, while
others may have more. Verify that both
visor clips are a minimum of 3” from the
center of the window, and a maximum of 8”
from the center.
