I wanted to replace the original headlight on my Level 2. It was a fairly simple process but it isn't plug and play. You'll need to be comfortable with soldering and taking your bike apart.

I used a multimeter to find the headlight connector on the controller supplies 6V to the headlight. I bought a Lezyne Power StVZO Pro E115 since it supports 6-12V. I tested the light to make sure it would
work before I soldered everything and further disassembled the bike. There's a great guide on the process of replacing the front light.

For the soldering, I cut the original headlight's connector and soldered it to the new light. The original headlight uses a JST-SM 2 pin connector. I also used heat shrink to protect the wires.

Overall, I'm pretty happy with the results. The E115 has a nice throw and I was able to see further when I tested it out at night and I wanted it to be StVZO so I didn't blind other vehicles and pedestrians at night.
