Bell Avenue Lights

Visit Our 2020 Show

The last day of our 2020 season will be Friday, January 8th, 2021. Stay safe and have a great new year! Visit our Facebook page for the latest updates.


Our home is decorated with thousands of LED lights, each individually controlled by a computer. The lights turn on, off, and change color in perfect time to music that we transmit on 106.5 FM.

Our show has been running every season for over 10 years and has become a tradition for our family and others. We invite you to stop by and enjoy the show.


Our show begins every night at 5:30PM. Most days it ends at 9:30PM, but on Fridays and Saturdays it runs until 10:30PM. When you arrive, tune to 106.5FM to enjoy the show.

  • Traffic gets heavy on the weekends, especially as we approach Christmas. Consider visiting on a weekday night to avoid the crowd.
  • For safety, shows may not run during bad weather.
  • Please do not block our neighbors’ driveways or use them to turn around. Feel free to use our driveway instead. Also, keep in mind that Bell Avenue is just a small circle. Instead of turning around, go straight by our house and around the block to see some other lights!
  • Be respectful of our neighbors and try not to make too much noise. This is a very quiet neighborhood and we’d like to keep it that way.
  • Please don’t roll down your windows with the music playing.
  • We suggest keeping your parking lights on for safety.


We’re located at 1716 Bell Avenue in Chambersburg, PA.

If you go west out of Chambersburg on Route 30, look for a Sheetz on your left just before Route 30 traffic becomes two-way. Turn right on Sollenberger Road at the red light. Go exactly two miles (stay left to avoid Johnson Rd) and then turn right onto Bell Avenue just before the entrance to Majestic Ridge.


Mike owns a computer service company, CermakTech. Heather was an elementary school music teacher for 15 years before becoming a stay-at-home mom. We both come from families who were known for hanging a lot of holiday lights. I guess this is what happens when you combine computers, lights, and music!

We’ve been running our holiday light show for over 10 years — longer than we’ve had children! Today, we are a family of five, with kids ranging from 2 to 9 years old.

We hope that our display will bring some joy and entertainment to members of our community. No matter what you celebrate during this wonderful time of year, we thank you for making us a part of your traditions.


Obviously, these aren’t store-bought lights. Each LED light has a microchip, allowing it to be individually controlled by a Raspberry Pi computer that runs the show. Programming each song is a time-consuming process and usually takes hours for each minute of each song.

We have a low-power radio transmitter running at 106.5FM. To abide by FCC regulations, it’s not very powerful and you’ll only be able to pick up our station when you’re near the house.

Assuming that today's winds don't cause too much trouble, we're hopeful that the light show will begin tomorrow evening. Keep an eye out for an announcement tomorrow to confirm. 🎄 ... See MoreSee Less
