Why anyone would want to ride in a dust cloud is beyond me. Just the same, I think I'll get the magnetic base light just for those rare occasions I'm in those conditions. I like being able to move it from the truck to the Jeep.
Can debate the relative merits of what color a rear facing light should be, but in the Desert SW the color most often used is amber. Right or wrong it is the color that those expecting to see a light at all are expecting to see. That it could be or is different in other regions of the country or world is expected and I would suggest using the color most likely to be encountered in the region where you are driving.
For those who want a rear facing light, but don't want it permanently attached I found a solution a long time ago when chasing a desert race with my old dune buggy. I mounted an amber fog light on an old magnetic CB antenna base. There's an Aspect Ratio of sorts to pay attention to here, either a really low mass light or a very serious magnet, or both, is the way to go. I used zip-cord for the power/ground wire and plugged it into the cig... er, "Power Point."
I have driven a truck on paved roads with a rear facing amber light permanently mounted in the rear bumper for over 100k miles. Obviously rarely turned on. I have been stopped for other things. I have NEVER been questioned by any of the PRK's Finest about that light.
It is fine with me if people want to drive slow. It is fine with me if people want to drive fast. What isn't fine with me is either of those people failling to consider those around them, even when there aren't any others to be seen around them. Stopping in the middle of the road, if there can be found a reasonable place to pull off, is inconsiderate at best. Flying around a blind corner at light speed is inconsiderate at the least.
FWIW some of the desert racing sanctioning bodies require a BLUE light in addition to the amber light. These are required of the slower classes precisely so that the faster moving classes DO NOT NERF them accidentally. Legal considerations of having a blue light on a vehicle aside, ideally a slow moving vehicle would have both colors facing to the rear. However, that is not prevalent across all of desert racing in the SW, so not everyone within even the desert racing sub-community will understand the meaning of a rear facing blue light.
WOW!
Biggest stupid jerk idea you can come up with. Just because you want to play "Rickey Racer", and the PUBLIC trails are being used by those who appreciate the scenery, respect the land, and do not want to crush those protected tortoise, lizards, birds, and even kit fox, and reptiles. As I read this, I see a jerk trying to bash his way along, at UNSAFE speed, and UNSAFE behavior off road. I have been going off road since I could drive in 1963, and have a little RESPECT for my fellow off roader, and RESPECT for the conditions and environment of the desert communities.
If you MUST scream across the desert, move to Saudi Arabia, or maybe the Gobi Desert!
^^^ cheap enough too. Good find.
Something like that would be good for dust storms and thick fog on the highway too. Not to mention our wonderful inversions.
Regular red tail lights are often difficult to see in the powder dust of the Southwest deserts until you are almost on top of the rig in front of you. An amber light of equal lumens is visible to the human eye from a greater distance, which is why the race sanctioning bodies specify amber for chase lights and why the general offroading population frequenting the Southwest deserts is starting to adopt rear facing amber lights as "dust lights." No drama at all.
