Review on 🔆 BRISHINE 10 PCS 921 RV Interior LED Light Bulbs - Super Bright 36-SMD 4500K Natural White T10 922 912 194 LED Bulbs for Camper Trailer Motorhome Marine Boat Indoor Ceiling Dome Lights (12V DC) by Shane Miller

I read to change the light on my caravan so I tried it and it's the best I could do. With old bulbs you would hear the inverter working and the more light the harder it will work. The lights were easy to install and make a huge difference. You can see the difference in brightness in the picture. So if you're wondering if they matter, I'd happily say they do! I also wanted to add that I measured the surface temperature and you can see the difference.
