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 Ashton Dahmer

We bought these to replace the #921 bulbs in our Jayco caravan. It was perfect! They put a white light, not yellow and not blue. (See attached pictures, original on the left, new bulb on the right.) They will only work if they are oriented in the right direction. So if they don't light up, just flip them over. No heat dissipation like the original bulbs which we like as we usually live in warmer temperatures. Excellent quality, sufficient quantity to replace any light bulb in our installation. Very happy with our purchase.
