Review on Debonauto-10 x T15 LED Light Bulb: Super Bright 6000k 12V T10 921 168 194 Trailer, Boat, RV, Landscaping & Camper Interior Wedge 24-SMD (Pure White) by Cody Wuol

Received a pack of 30 bulbs to replace 921 bulbs in my 28ft trailer. I'm so tired of old lightbulbs getting so hot. These are amazingly bright lights. Minimal heat, more light and pure bright white. I wish I had done this many years ago. For less than $1 I suggest you try them. They MUST be set correctly for polarity, but they are so easy to install that this is not a mistake. I recommend, I will buy again. I've seen some reviews saying they're quite difficult to install, but they went in very easily for me and my 11 year old son.
