  1. Great bulbs! 5 Star Review

    Posted by on 2nd Mar 2019

    We had fourteen 921 and 912 bulbs in our motorhome and these are perfect replacements for those incandescent wedge base bulbs. One caveat: these bulbs are longer/taller than 921/912 bulbs, so they may appear a bit obtrusive in downward-facing fixtures. We ended up exchanging four of these LED bulbs for a smaller version also carried by M4 that cost a bit more but look nicer when the entire bulb is visible (and are still very bright). Thanks to Steve for helping us out with the exchange.

  2. Great Discovery 5 Star Review

    Posted by on 9th Dec 2018

    While searching for LED bulbs for my RV I came across M4. Their company and products were highly recommended by several RV users and companys that sell RV products. Their website is very user friendly, informative, and made selecting LED replacement lights for my RV easy. Customer service is outstanding. They shipped my order the same day. The bulbs fit perfectly and look great. Thanks for being an outstanding American Company.

  3. Going to LED lighting in my RV 5 Star Review

    Posted by on 6th Nov 2018

    Decided to switch out the standard bulbs in our RV to LED bulbs. The difference is great on three points. Better lighting, way cooler than the standard bulb, and the use of battery power so lights can be left on longer. Don't have to rush to do something and then turn off a light.

  4. Great quality! Happy we finally transitioned to these LED lights! 5 Star Review

    Posted by on 5th Nov 2018

    Natural color, very bright and we can leave the lights on without worrying about draining the battery too quickly.

  5. Upgrade RV lights to LED's. 5 Star Review

    Posted by on 28th Aug 2018

    New to my RV, folks told me to get rid of the power hungry incandescent light bulbs in my RV and get some LED's. Everyone on the RV forums said to use m4products to get quality LED's. I bought 13 of the Warm White 5050 SMD light bulbs. Very quick shipping and well packaged. Bulbs arrived in perfect shape and are all installed. Very tight fit, you must be careful installing. Thanks m4products. Will do business again.

  6. LED Rerofit 5 Star Review

    Posted by on 3rd Aug 2018

    I swapped out the incandescent lights with LED's in my RV. What a difference! Very little heat output(and I'm sure reduced energy consumption). No regrets with the purchase. M4 was very helpful in making sure I got the right replacements. Would definitely order from them again.

  7. Now we can see! 5 Star Review

    Posted by on 25th Jul 2018

    The LED bulb under the range hood in our trailer was useless. I saw a review of M4 LEDs in my Trailer Life magazine and ordered this. Excellent price and superb performance!

  8. Great colour 4 Star Review

    Posted by on 23rd Jun 2018

    The colour of light of the bulbs pretty much matches the replaced incadecent bulbs!! Now to see how long they last...

  9. 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.

  10. Excellent product! 5 Star Review

    Posted by on 13th Jun 2018

    Love the new lights, brighter and easy to install, using less energy, and service was great! Thank you!
