Tell me about this modular filter system? They look like they are just a plastic cover? Surely they will just shatter or crack with a severe impact?

As standard all current LIGHTFORCE driving lights are supplied with a CLEAR SPOT CLIP-ON filter. All LIGHTFORCE driving lights are designed to be run at all times with a filter in place. We use polycarbonate as used in fighter aircraft canopies, security screens etc. If you have any doubts about durability just check our ‘LIGHT LOGIC’ video! Literally thousands of people worldwide have stared in disbelief when we display this at trade shows. The filters install with no tools required and in seconds you can change the beam pattern and or colour to suit your situation. Customers tell us how much they love this feature! Check for yourself on many offroad internet forums. Fog, rain, snow, desert silt or Australian bulldust you have the ideal solution at hand!
