Cool White LED lights GREAT
I have been slowly getting rid of all the 921 bulbs in my fifth wheel. These bulbs fit great and are very bright. Wish they were a little less expensive. That's my only negative.

Cool White LED wedge lights are FANTASTIC!
We bought 2 of the cool white LED wedge lights and they were so fantastic that we are now ordering 15 more so we can replace the rest of the ceiling lights in our Itasca Sunstar. Price and quality are excellent. We have also ordered 2 cool white 1156 LED reading light replacements.

Wish I had bought these lights a long time ago
I bought 14 of these lights to replace the regular lights that came with my RV. They fit perfectly and I love the light they put out. With the old lights if more than two fixtures were turned on the fan on the converter would start. With these I turned on every light in the RV and no fan heard. One of the lights was defected and I emailed customer service. In the space of an hour I received a reply that they would send me a replacement bulb. Great Lights! Great Service!

Great Light output
I bought 6 lights/ 3 cool light and 6 natural.Being a senior citizen I liked the higher out put and the color of the cool white lights had.They were bighter and used less energy than regular lights by 2/3 rds. I plan to retro fit the rest of our trailer with the led bulbs as soon as I can afford them at a sale price.I have about 8 more bulbs to replace.I like the video on how the product is built better and the difference construction of bulbs makes.I want the best quality I can get for my money and these are the best.THX

Changed 5th Wheel over to LEDs
I replaced 34 lights with these Leds, they all work fine, really lite the RV up. I have some more I'm going to change over. M4 has the best prices on RV LEDs. You can't go wrong with these lights.
