Review on 💡 Super Bright T10 921 922 912 LED Bulbs: 12V RV Interior Light Trailer Camper Dome Lighting, Pack of 20 by Brad Russell

I just pulled out the old glass bulbs and they fit right into the socket with no problem. What difference do these headlights make, they put out twice as much light and it's pure light (e.g. outdoors during the day instead of the usual yellowed indoor light) but they only use about a fifth of the energy (4W vs 20W). I have replaced all the original bulbs in my camper and having LED I know they will last 10 times as long. As you can imagine I am very happy with my purchase.
