Installation & Compatibility Guides
Select 20C-D5OS by the lighting task, beam, complete mounting assembly, supply and confirmed package contents.
Match 20C-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.
Compare the listed bracketed envelope of 21.4 inches wide by 4.125 inches high with the exact drawing and planned support points. Check rear clearance, wiring access and aiming movement. Confirm the 20C-D5OS light and supplied electrical ratings before installation.
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.
