About Design My Lights

Every year, millions of homeowners spend hundreds — sometimes thousands — on Christmas lights without knowing what the finished result will look like. They guess at colors, guess at spacing, guess at how much they need, and hope for the best.

We built Design My Lights to fix that. Upload a photo of your house, drag lights along your roofline, and see a photorealistic nighttime rendering before you spend a dime. Pick your bulb style, choose your colors, add wreaths and bows — and know exactly what you're getting.

How it works

Our design tool uses a photorealistic rendering engine that simulates how Christmas lights actually look at night. It darkens your daytime photo, then renders each individual bulb with accurate glow, bloom, and light spill. The result looks like a real photo of your house at night — not a cartoon overlay.

What we believe

We think the best tool is the one that helps you make a decision you're confident in. That's why Design My Lights is free, requires no account, and works in 30 seconds. We make money through advertising and affiliate links to the products we recommend in our guides — not by charging you to use the tool.
