  5. Change for the Best !! 5 Star Review

    Posted by on 31st May 2018

    Bulbs installed very easily. Provide excellent lighting for my trailer. Reduced the number of lights that were needed for proper lighting to just a few of these. I purchased as a test and will be replacing the rest. Thanks

    The difference between these lights and the factory ones I can with my truck is unimaginable. I knew there would be an improvement but I never imagined it would be this great of an improvement. I highly recommend these bulbs.

  7. Travel Trailer LED'S 5 Star Review

    Posted by on 14th Feb 2018

    Super Fast Shipping , I ordered 18 of the 5050 warm white and 1 of the 5630 natural white to replace all the 921 bulbs in my travel trailer. The M4 bulbs were all individually packaged and well made. I replaced all the bulbs in the camper within 10 minutes and it is the brightest i have ever seen it on the inside. One final note prior to replacing the 921 bulbs, my inverter was running with just one light on with two of the incandescent bulbs in it. After replacing all the fixtures with the M4 LED'S, i turned all 18 bulbs on at once and the inverter never came on.

    M4 Note: Typically what you hear (or don't hear in this case), is the battery charger cooling fan. With less load, the fan does not come on, which is very nice when camping on shore power.

  8. Excellent Product well made and lasts. 5 Star Review

    Posted by on 7th Nov 2017

    Product meets specifications and throws out alot light. Well made and not the cheap china made like other LEDs I have bought via Amazon. Delivery was prompt.

  10. 100% Working upon installation and bright 5 Star Review

    Posted by on 9th Aug 2017

    M4 Products is the best company to do business with. Not only do they have a first rate product, their customer service is beyond any company in America that I have dealt with. My product was missing from the mailbox (USPS said they delivered it there). After a lot of checking with USPS and getting no where, M4 sent a 2nd batch to me for no cost on my part. Can you believe that? Owner is awesome.
