AT one time, Cabelas AUTO/TRUCK catalog offered a clip on LED strobe running light to replace the red flag on extended loads at night.
Might be a good investment IF your hauling canoes at night with a smaller vehicle/trailer.
 G01, I worked with commercial trailers for a dozen or so years in the building trades. Besides the bearing issue, it was amazing how many times people lost a wheel due to "tight" lug nuts coming off :-?
 Culprit was usually the person who mounted the wheel, NOT crisscrossing the lug pattern as they tightened the lug nuts.
 If you go in a circular motion, you risk the wheel not being tighten flush with the drum. AFTER X amount of miles you get a wobble and eventually lose a wheel, or break off the lug bolts :'(
