(9.525-mm-) diameter eyebolts and carry the light assembly to
the base. Align the light assembly with the runway for proper
light direction.
3. Place the light assembly beside the opening in the L-868B base so

base. Align the light to the runway centerline. Make sure items
such as spacers, shims, and gaskets are installed on the light base
per site plans, specifications, and drawings. Remove the eyebolts
and lifting rod.

Operate for a minimum of five minutes.
CAUTION: The light assembly will be hot after this test.
Allow time for assembly to cool before proceeding.
