  1. Great color and output 5 Star Review

    Posted by on 19th Jun 2018

    Only negative is they were very difficult to insert in the bulb socket. On the other hand, they will NEVER fall out from road vibration!

    M4 Note: Some sockets can be tighter than others. The best method on tight socket is to press firmly on the top of the LED and at the same time rocking it back and forth along the length of the tab (not against it). They generally drop right in. As noted on the packing list, you can also use a little dielectric grease if necessary which will also protect the connection in the socket.

  2. Excellent product! 5 Star Review

  3. Overhead RV Replacement light 5 Star Review

    Solid product. These lights are brighter than the original bulbs and the warm white give off similar color tone to the incandescent bulbs.

  5. warm light LED 5 Star Review

    Posted by on 29th May 2018

    Replaced two previous led lights over my dinette that were inadequate. These lights are perfect and shed the light I need over the table. I like the warm color in this area instead of the bright daylight type which for eating I found to be too white and not warm enough. The light were received very timely and in good condition.

  6. New Camper Light Bulbs 5 Star Review

    Posted by on 12th Mar 2018

    I purchased these bulbs as a replacement for our standard #910 light bulbs in our camping trailer. I was instantly impressed about how much brighter they were. I was told about 10%, but in my opinion these bulbs are at least 33% brighter. They have a very nice bright warm color and when I finally get all the bulbs replaced (winter for us) and working I think our trailer inside will look so much better and brighter. At this point I have to feel they were worth the money, especially if they last a long time. We have battery issues when dry camping like everyone else so I'm excited to see if these bulbs can be left on without running the batteries down each night. Was told that these bulbs have only 10% of the draw. Very easy to install and all of my 16 worked perfectly. I was impressed.

  7. Replacement from Standard to LED 5 Star Review

    Posted by on 21st Feb 2018

    Could not be happier.
    Great light, warm white color now getting the rest of the 5ver changed over.
    Will alway deal with Steve(M4 Products).

  8. Replaced original bulbs in camper 5 Star Review

    Posted by on 29th Jan 2018

    We noticed that the original lights in our camper put out so much heat. These new led bulbs are just as bright, do not feel like you’re standing under a heat lamp and they do not pull nearly as much power from our battery when we’re not hooked up to electricity. I hope they last a lot big time.

  9. Great fit, quality, and price! 5 Star Review

    Posted by on 9th Jan 2018

    Love these LEDs. They really brighten up the dining area where I installed them. I'll be back for more M4 products in the near future as I get my trailer ready for extended boon-docking!

  10. Love! 5 Star Review

    Posted by on 7th Nov 2017

    Love the light and reduction in energy use!

    Even better than these bulbs is the customer service and of M4! So helpful in assisting us in determining the correct bulbs and type to replace all of our bulbs with LED and got them so fast! THANK YOU M4!
