I bought a 12V rear light off aliexpress so that I wouldn’t have to keep taking my SL-300 off and on.

Pretty cheap, but I hot-glued it to a go-pro clip so that it can live on my rear mudguard where the shredlight used to be.
I also got really fed up with the light-switch I was using to turn my 12V buck on and off (it kept accidentally going off and on), so I bought this very nice metal handle-bar switch:

I have it wired so that the first on-off switch toggles the 12V buck. Red rear light is always on if the buck is on, and then the 1-off-2 toggle switch currently turns the super bright front light on. I plan on wiring an additional white ring light as the 2nd option, so that I still have some front light I can use that doesn’t blind pedestrians on the sidewalk or car drivers in the mirror in front of me 
The rear light is equivalent to the SL-300 shredlight on the 2nd brightness setting (1st one was too bright anyway I think), and has good side visibility as well 
This bike has been pretty decent in winter. The front wheel drive is very deadly in snowy conditions (have already wiped out twice lol; you can’t steer if you lose traction in the front), but it does actually work as 2wd for more traction if you’re careful! 
I do low-key wish I had gone rear-wheel drive, because then I could try drifting with this thing 
Btw, this is how I avoid melting muddy snow dripping on my apartment floor
Unfortunately though, after leaving my bike outside in ~ -8C weather, the throttle broke! 
I guess I’ll try to drill a screw through it as a temporary solution. Maybe I need to find a metal throttle, but I really liked how this one felt 
(Although it still was pretty jerky to control. Not sure if that’s due to vibrations in handlebars being inevitable, or if it’s the chinese ESC)
