Are you talking about the roofline lighting?

Are you thinking they are lights that are sphere shaped stars to give that effect? I'm wondering if it isn't just the way they are photographed that make them look like stars/satellites, because if you look in the window reflections they seem to be plain lights.

Christmas light photos

They look like the lights that 'custome home decorators' use. They decorate homes for a fee. Likely just oversized round bulb lights. Might be commercial grade? I would search online, for sure! Every year they have a new dream. Now things are LED....which takes alot less power! So if you want to go all out, LED Bright would be something I would think to look for! They also have magic lights...you can control the color by remote...so if you have a yard lamp out front...you might want to see if you can get those bulbs for the yard lamp? Fun??? !! Yes. So many new things to learn about it seems like! https://www.amazon.com/myCozyLite-Waterproof-Perfect-Transformer-Extendable/dp/B07233B261/ref=pd_sbs_60_1?_encoding=UTF8&pd_rd_i=B07233B261&pd_rd_r=7f26a358-cf4d-11e8-a1fa-3b320cf86cd1&pd_rd_w=tvZpl&pd_rd_wg=2FQ3G&pf_rd_i=desktop-dp-sims&pf_rd_m=ATVPDKIKX0DER&pf_rd_p=7d5d9c3c-5e01-44ac-97fd-261afd40b865&pf_rd_r=86G3MG5DBFK0NYXA0C3D&pf_rd_s=desktop-dp-sims&pf_rd_t=40701&psc=1&refRID=86G3MG5DBFK0NYXA0C3D and here you go..Commercial..https://www.amazon.com/Commercial-Outdoor-Christmas-Wedding-Lighting-Uzexon/dp/B074WT2SMS/ref=asc_df_B074WT2SMS/?tag=hyprod-20&linkCode=df0&hvadid=232831470222&hvpos=1o3&hvnetw=g&hvrand=6603963049941058667&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9027311&hvtargid=pla-392038723602&psc=1

Wonder if you could just rent them from a local rental business? Must be heck to store and take down without breaking? Good luck!

To me, they look like waaaaay too much climbing and work for a look intended for only a couple weeks out of the year.

If I were still lighting up the exterior of my home for the holidays, I'd be considering "projection" -- something like

They look like globe lights to me, too. The starburst effect is due to the photography. You can find them with either clear or frosted glass. The ones in your photo are hung with hooks that keep them straight/even. The lights should be easy to find. The last ones I bought were at Target. I've seen them in different sizes. Mine are about the size of a golf ball.
