Convert Daytime Bike Scene to Cinematic Night Scene (with VFX)

I need to transform a daytime bike scene in my short film into a night scene. The scene features a hero sitting on a bike on a road with moving vehicles.

Requirements:
- Night color grading for a moonlit look with minimal artificial lighting
- VFX to make the bike's headlight appear turned on
- Add light reflections for added realism

The final scene should look natural and cinematic, as if it was actually shot at night. Ideal skills and experience:
- Proficient in color grading and VFX
- Experience with night scene enhancements
- Strong attention to detail for realistic light reflections
