Installation & Compatibility Guides
Select 40C-D5OS by the lighting task, beam, complete mounting assembly, supply and confirmed package contents.
Match 40C-D5OS and its combination flood / spot pattern to the actual target area. No road-use or navigation-light approval is established by the product name.
Assess the specified combination flood / spot beam and planned aiming position. A curved housing or a higher raw-lumen rating does not establish the illumination at a particular target.
Check the listed bracketed envelope of 41.4 inches wide by 4.125 inches high against the full model drawing. Confirm the span and strength of the supports, rear lead clearance and aiming range. Match the supplied light and harness ratings before connection.
The light’s published input range is 12–30V DC. Verify the delivered light label and the voltage ratings of the supplied harness, relay and switch separately. Follow model-specific circuit-protection and conductor requirements.
One light bar, mounting brackets and a wiring harness with fuse, relay and switch. Check the delivered package before selecting any additional installation parts.
Follow the exact mounting and aiming instructions. Check secure support, cable protection and reflected glare before operating the light under its intended conditions.

Choose the profile by actual assembly geometry and desired beam placement. Confirm the complete drawing, circuit requirements and supplied parts separately; a matching nominal length is not evidence of a direct swap or identical illumination at a target.
