Installation & Compatibility Guides
Select 20C-S5OS by the lighting task, beam, complete mounting assembly, supply and confirmed package contents.
Match 20C-S5OS 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 delivered drawing for the full assembly, support points and aiming movement. The source lists a 23-inch bracketed width, while other assembly references vary; measure the supplied brackets before modifying an opening or replacing a light. Review the light and harness voltage ratings separately.
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.
20C-S5OS is the black 20-inch single-row combo model. 20CM-S5OS is the white version. Both listings specify 100W and include mounting brackets plus a harness with fuse, relay and switch.
Confirm the finish and exact mounting arrangement before ordering. Their source listings give different bracketed widths, so neither nominal size nor the shared electrical rating establishes interchangeable bracket centers or identical installation clearance. Review the Black Oak Pro Series 3.0 Single Row 20" LED Light Bar - Combo Optics - White Housing MPN - 20CM-S5OS as a separately sold option.
Choose a lighting family by the task, mounting arrangement and electrical requirements of the actual installation.
Compare beam pattern, mounting geometry, electrical requirements and confirmed package contents for each model.
