How to add lighting to any ebike for cheap.( best guide 2023)

Where did you get the fender tip on your seat.

I thought about doing the same for my bike but in the end I just added another battery pack purely to run the lights and not sacrifice range and if the worst happens and I lose main power at night travelling I can still see

Link for the stepdown & light kit please.
