H3 bulbs are common to Weekend Warrior(tm) and other trailers with external spot lights and have a replacement LED light. If you never use your outside flood /docking lights because they draw too much power, you can get 80% of the light out of these bulbs while using a mere fraction of the power of the standard Halogen H3. This bulb has an 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.
This is not intended use as a replacement for forward facing driving lights as it is not made to be brighter, but made to be efficient in side docking and flood lights. For forward facing headlights see our Headlight/Fog Light HEADLIGHT-H3-BLADE
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.
- Draws only .18 Amps at 12.8 Volts (2.3 Watts)
- 42 Bright 4014 LEDs at the end and sides to light up a large area
- built in aluminum heat sink
- standard H3 base plate
- Cool White Color

Second order
Ordered lights for half the RV a few months ago. Very easy to install/convert with the Youtube video and the provided instructions. Made another order a few weeks ago and now RV is 100% LED. Thanks M4:)

Great replacement bulb
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.

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

Great Retrofit Light
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.

H3 LED retrofit works great!
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!

WOW WHAT A DIFFERENCE!!!
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.
