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 Brockington Zuniga

These "light bulbs" were a great energy saving upgrade for our camper. There was enough in the pack to replace all the bulbs plus a few extras. Just take the old one out and put the new one in. If you can change a lightbulb, you've got it. Note that LED bulbs are very sensitive to voltage. When your battery's DC voltage drops, regular lightbulbs 💡 simply dim and turn amber. The LEDs dim a little and then don't work at all. Just testing these lights on my battery, I found I had a bad battery that was only outputting about 10.5 volts and not lighting the LEDs. They turn back on at around 11V and of course work fine with an AC/DC charging voltage of around 14.7V. The more you know! I would like to repeat this update!
