Well, heres the whole scoop on that light rack and the visor with the zip ties:
I wanted to make a rack that can hold some lights and also serves as an extra storgae space for long trips, but can be removable when not needed since this is my daily driver.
So i fabbed up the rack and attached it via 4 yakima mounts which are commonly used for all their systems. Everything worked out great, although i overlooked one crucial detail....
I forgot about the glare facotr that the lights have, the way my rack is designed i was getting a lot of glare from the 3 lights even though they are pencil beams, so i had to add that visor underneath them, where i also over looked a crucial detail...
I used fairly thin sheet metal, and bolted it to the 3 studs of the lights, at street driving it was fine, but at about 75-80, at starts flapping uncontrolably, and scared the **** out of me the first time it happened, which was on the way to san felipe so i had to engage the good ol zip ties.
As to the wind factor, yes with the lights and stuff in the rack, the wind drag is def a problem, grades that i did in 5th gear before i put it on, had to be done in 4th. But im sure all these other rigs have similar problems especially with those tents up top.
But the 3 pencils up top and the 2 euros on the bumper are a great combo and work really well on the trail at night. When i go on short trips i usually dont bring it with me, so the flexibiltiy of being able to take it off works out fine.
