(1) Purpose: Improve near-field & peripheral vision during inclement weather. Does not need to light up much farther than regular low beams.
* Easy mount --> Projector units are more compact for a given wattage and equivalent lighting effect
* Fog beams that do not cause glare in fog/rain/snow --> sharp cutoff
* As small as possible
(3) Choice: Hella Optilux 1802 (Black housing, slightly blue lens). Comes with clear 55W H3 bulbs that emit deep yellow beams. The projector unit has a plate that permits a nice sharp cutoff. Retail price around US$30-60 (depending on where you buy them). Slightly smaller than the Optilux 1002s.
(4) Materials required: Metal brackets, screws, washers, & nuts.
(5) Mounting method: Cut a bracket from any rigid plate to mount the lights to the front clip or the headlight frames. Picture below shows a smaller aux light, but the idea is the same.
