The 69-year-old actor, who was recently admitted at a hospital here for a check-up, will be seen in the new ad campaign directed by filmmaker R Balki.
The Havells fans commercial features Khanna going down the memory lane, remembering how his fans used to follow him everywhere when he was a superstar.
"To be approached after so many years is indeed a great honour for me and I am delighted to reconnect with my fans once again. Shooting after a gap of so many years has definitely brought back fond memories and I feel that not a lot has changed at all. It's good to be back," Khanna said in a statement.
Balki, who has directed films like "Paa" and "Cheeni Kum", said, "When the ad was being conceived, we could think of none other than Rajesh Khanna himself who still commands a great deal of respect and maximum fan following... It was a huge achievement to direct Mr Khanna in his first ever commercial."
