Review on Ultra Bright T10 921 912 LED Bulb For RV Indoor Lights Camper Trailer Motorhome And Marine Boat 12V Interior Dome Light (Pack Of 10 by Eric Garron

I looked for bulbs that work great, but only 12 bulbs worked perfectly, the bulb on the left in the picture. The other 8 bulbs do the same as the right one, they "turn on" but clearly aren't working properly. I am only trying to return 8 defective bulbs but I think Revain will require that I return all 20. I will let you know when I resolve this return issue. Update: Revain instructed me to return only the 8 defective bulbs and sent a full replacement in a pack of 20.
