MINI LF Housing Operation 

Page 45 

 

Lighting Systems  

 

The MINI LF Housing has provisions to utilize a variety of lighting systems. Ball mounts 
for the light arms may be located in several locations on MINI LF Housing: a) threaded 
into the top of the Handle Grips:  b) on the Foot Rails; or c) onto accessory mounts that 
slide onto the same dovetail slots as the handle grips.   
 

Controlling Reflections  

While it is unlikely, you may encounter reflections from within the port area of MINI LF 
Housing from anything shiny.   

To control such reflections Gates recommends two easy measures: 

 

Blackening the shiny area 

with a black permanent marker; or

  

 

 

Install a mask over the lens, as shown in the photo.   

This measure is rarely 

needed, but if necessary black neoprene makes an excellent, flexible masking 
material.  Cut to your specific lens and cut the outer ring diameter to fit the port.   
 
Note: Lens masks are not provided by Gates. 

 

 

 

If reflections are encountered, a 
mask can help minimize the 
problem.
