Denali S4 2.0 LED Light Pod With DataDim Technology The S4 lights were built to reduce cost without losing performance, quality or durability. Actually the S4 features the same high intensity LEDs as the D-series lights, but uses a single piece optic and sealed beam construction to reduce the number of unique components. Mounting brackets are sold separately. S4 light pods mount using a single 8mm bolt, 20mm long. Common mounting options are bike-specific Denali Auxiliary Light Mounts, Denali Auxiliary Light Crashbar Mounts or other solutions that accept 8mm lighting hardware.
