Problem Statement

A significant section of India lives without lights – even during the day their mud walled and thatched roofed houses do not get day-light.

We therefore decided to make a significant dent during Diwali by reminding everyone, that there is a part of India who needs us to come together & brighten up their Diwali.

Identified Objectives

Our task therefore was to bring alive the brand promise of “Maximizing Moments” in a way that it effected society.

The Strategy/Execution

We tied up with a global foundation Liter of Light & installed empty Pepsi bottles filled with water & bleach on rooftops of houses which enabled absorption of solar energy & illuminated houses.

With the help of LOL technology team, we also created street lighting with Pepsi bottles attached to a night solar panel & installed in GJ, MP & TN where Pepsi’s plants were built.

The content was brought alive via moving digital film that spread organically across the YT world & we retargeted them by several other testimonial videos of villagers & urged consumers to volunteer & join the cause by donating.

  • Vernacular dissemination: Used native platforms like GajabPost etc to geo target our audience on social
  • Google programmatic native social: was used for the first time which resulted in 52% CTR
  • YT Programmatic Approach: For the first time, Pepsi used programmatic tool on YouTube to target audience layered with the intelligence of ad engagement during previous campaigns.
  • Real Time Optimisation: was done on YT using high engaging affinity genres/days during the weeks/and festive keywords resulting in maximizing views during peak festive season.


This Diwali was special & it lasted a lot longer than 4 days not just for the ones who celebrated it but this time India came together to extend the festive season & spread the joy to the dark side of India as well.
