I do want to share a success story re visibility improvements....not wanting to dive into running any electrical wires I got a completely wireless review camera. Completely. There are 2 on the market that I have found, this one seemed more water proof (based on comments) and solar power...rechargable via USB (but that remains to be seen ...the USB port is way in the back and may have to take the plate off to recharge...will see and cross that bridge when it comes to it. Supposed to last for months on single charge)
Here is box
Camera was designed to fit on top of the license plate..it arrived already stuck to the license plate backing plate...you could take it off of that which is what I did. Note, I had gotten after market Tesla labeled plates for fun so this may fit differently on your plate frame.
I had to drill a couple of holes in the plate frame (it only had 2 at top) the frame was stainless steel but no big issue to drill holes. It was too thick along the sides to fit in the groves with the provided back panel from the camera kit. There may be another solution (eg design/use another back panel ) but this is what I did: I trimmed off the edges of the license plate outside frame and then everything fit fine. Note I don't have my final license plates yet (just the paper ones) so may have to revise when they arrive.
the solar chargers fit fine.
The camera instead of going on top as pictured on the box (as the tesla bumper light is in the way there), I flipped to go on the bottom. While it was stuck very securely with the tape they provided, I am a bit of belt and suspenders kind of girl, so added a thin stainless bracket I made to go from each of the bottom screw holes in the license plate/holder, and bent to provide an edge support to the bottom of the camera
The mount stuck securely using a suction cup in the spacious front seat area (ha!) of the roadster. just plug in to the 12v lighter spot . It comes on automatically and then goes off (user defined 30,60 or 90 sec "on" period...I also unplug after backing out so I can use 12v for phone).
Good back up image, Not 170 about 140 degrees. But good enough. With helpful back up lines.
