Product Description

Click Image for more pictures and specifications.

H3 bulbs are common to Weekend Warrior(tm) and other trailers with external spot lights and have a replacement LED light just for you.  If you never use your outside flood lights because they draw too much power, you can get 75% of the light out of these bulbs while using 1/4 of the power of the standard Halogen H3.  5050 SMD LED bulbs are not recommened for these housings because they put out less light, and they will overheat.  This bulb has an oversize aluminum heat sink to last in the sealed housing.

This does not replace full sealed beam halogen lights, if you housing looks similar, but you have a sealed beam light with wire lugs on the back, click here.

These are a single circuit high power LED for ON/OFF housings common to these trailers.  They can also be used in HI/LO housings, but you will only have one setting and will need to add a pig tail ground to the base. 

  • 5 high power LEDs at the end and sides to light up a large area
  • built in aluminum heat sink
  • standard H3 base plate
  • Cool White Color
  • housing is cool to the touch, even after 12 hours of continious use.

  2. Great replacement bulb 5 Star Review

    Posted by on 2nd Jun 2017

    When I received these retrofit flood bulbs I needed help with how to wire them I to my trailer. I contacted m4 and got an immediate response and the guidance I needed. The install went very well. I'm very pleased with the brightness compared to my old bulbs and look forward to not having the battery draw I had with the old bulbs.

    Easy installation and excellent lighting. Was exactly what I was looking for in a low power lighting application to save RV battery usage.

  4. Great Retrofit Light 5 Star Review

    Posted by on 3rd Mar 2017

    This Retrofit Light seems to work very well and was easy to install. I have not had a chance to field test, but in the driveway test it performed excellent. I was most impressed with the service I received as (Steve) was very patient and therefore I received all the correct lighting I needed as I ordered several different bulbs. I am very happy with all the M-4 products I have used so far.

  5. H3 LED retrofit works great! 5 Star Review

    Posted by on 14th Sep 2016

    I had difficulty locating replacement H3 bulbs for the docking lights for my Lance truck camper. I had already replaced all of my interior lights with LEDs from M4, so I was happy to see an LED replacement for the H3. Like an earlier review noted, the bulb is just a little larger than the original, so I had to modify the opening in the fixture. It took no more than two minutes with a Dremel tool to make the adjustment in each light fixture. They are plenty bright for my purposes, and using only 1/4 of the power makes my battery happier!

  6. WOW WHAT A DIFFERENCE!!! 5 Star Review

    Posted by on 2nd Oct 2015

    I changed out my docking exterior docking lights on my 2008 Monaco Dynasty with the H3 LED retrofit light which Steve brought to my attention. I use my docking lights often and thought lets see if there is a big difference and boy was there ever!!! Very pleased with them. The only small issue I had in replacing these was the LED bulb was just a tad bigger in diameter than the 12 volt bulb in the fixture and in order to get them in I had to make the opening slightly bigger by use of a small round file. A little more work trhan I had hoped for, but well worth it in the end.

  7. a little disappointed 3 Star Review

    I was hoping this bulb would be brighter
    It works and I appreciate the lower current draw but not quite what I expected

    M4 Note: Please note our product description above " If you never use your outside flood lights because they draw too much power, you can get 75% of the light out of these bulbs while using 1/4 of the power of the standard Halogen H3"

  8. H3-HP75-CW 5 Star Review

    Posted by on 28th Mar 2014

    I just installed these on my Weekend Warrior and really like light. Easy retrofit and light emitted is just as described.

    Look forward to lighting up my camp with "new" M4LED flood lights!

    I would highly recommend to anyone who is considering switching out from old "yellow" bulbs.

    Steve, Thanks for answering any questions I had with these.

  9. 7.5w LED replacement for Weekend Warrior 5 Star Review

    Posted by on 8th Aug 2013

    Replaced the HID in the outside spot lights with this replacement LED bulb. Very simple conversion only had to solder a ground wire to it. Looks great at night and uses a lot less power.

    -M4 Note. Added ground is necessary for fixtures with original high/low bulb. Fixtures with on/off bulb plug right in.
