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.
