Best described using the diagram below, the side brackets should be assembled in order of components: Bracket Arm > Washer > Spring Washer > Bolt.
The bracket is easiest assembled prior to installation. Using the wider opening in the channel of the light bar, insert the bracket and slide to the desired position for mounting. Once the bracket is in position, tighten down the 2 cap screws to the locking plate firmly to secure the position in the channel.
Note: When installing the sliding bracket into the light, the foot may need to be rotated so the lobe clears the opening. Alternatively, the bracket can be assembled once the track insert is on the bar. Once the bracket is fitted and the light is angled to the desired position, tighten the 2 locking grub screws on each side of the brackets to secure the light firmly.
Due to the high current draw of this ST3303 Pro light bar, STEDI insists you MUST use the included wiring harness. The included wiring harness is sized specifically for the extremely high-power consumption of this light bar, we DO NOT recommend the use of any other harness. Strong earth and power connection are necessary for maximum performance. If poor earth or power connection is encountered, symptoms such as low brightness, flickering, or fuse failure may be encountered. Always use lubrication on all stainless hardware to prevent stainless locking upon itself. This phenomenon is known as “galling”. WD40, Vaseline, or even saliva will save any possibility of a stainless bolt seizing.
