Automotive Headlight Projector Mod V1.2

Out Dated Mod:

The projector mods I did are out dated at this time. There are projectors with much better optics, brightness and throw distances. If you looking for a long use projector, with inexpensive bulbs, like I was when doing this mod, I would suggest getting an LED based projector. They provide superior brightness, rich colors, and most of all ridiculous long life spans over using a bulb based projector. Most of all there very inexpensive. Seriously Check out Amazon for LED Projectors. Just remember to find the Native Resolution, Brightness, Inputs and check the user reviews before making your purchase.

Considering what you can get NEW and at a reasonable price, modding is just not worth it.

Modding your projector on the cheap!
With the simple use of a 12V Automotive headlight and a power supply.

The OEM replacement bulb for my projector cost ~$300! More than what I paid for the projector it self. And my power supply that powered the original bulb was almost toast. Using this guide you can use an automotive head light bulb for about $15 dollars.

WARNING: This mod involves modification of a power supply, projector, and a high power bulb if you are not comfortable with moding on this level, DO NOT attempt this mod. The writer is not responsible for any injuries or damages resulting from these instructions.

Gathering Parts and Supplies

For this mod you will need the head light ($7), power supply (old PC supplies work well $5), and some good gauge wire ($2), thin bare craft wire ($1), pliers and other tools. And oh yeah, one projector with a burned out bulb (E-bay).

Finding a Bulb

First begin by estimating the amount of space allotted for the normal bulb. If you have one that takes a bulb cartage youll have to find a bulb that fits into the cartage if possible. The standard size of the auto bulb fits mine well. Now you know about what size bulb you can buy. (I recommend a 9004 XV from Sylvania, others may work as well. Youll want at least a total of 110 Watts).

This mod "should" work on all projectors that can fit a high power headlight bulb in the area that would normally hold the original projector lamp. Most all newer projectors use a lamp cartridge that houses both the bulb and the non conductive reflector. You would have to find a suitable bulb and insert it into the cartridge. Most automotive bulbs are of the size I used in the instructable. Remember you need A LOT of light output, so a wattage of 110+ at 12v is recommended. (Add the high and low wattage values).The nice thing about my projector, the MVP800 is that is has no cartridge. It uses a glass bulb shaped like a rod with a ball in the center. The reflectors and lens are all part of the projector. (The round reflector closes around the bulb witch has been removed from the projector in this picture)

Extracting the Bulb!

Next youll mostly likely have to remove the base that holds the actual glass bulb. This is the most difficult part of the mod. Youll want to wear gloves and use lots of patience when extracting the bulb from the base. I broke the prongs out of the bottom of the base then used side cutters to free the bulb from the metal holder toward the top of the base. After it was loose I worked the bulbs thick leads back and forth until I was able to cut them at a reasonable distance. You dont want to break off the power leads to the bulb or you will ruin the bulb.

Wiring the Bulb

After it is extracted you need to use butt splice connectors to tightly connect both the standard and high beams together to a +12V and ground lead to be strung out the side of the projector. There will be three or four leads. Look through the glass to find which lead goes where, and activate both the regular and high beams at the same time. I used automotive connectors so I can change the bulb out if needed. To hook the PC power supply to the bulb connect a +12v lead (yellow) and a ground wire (black) to the automotive bulbs contacts. You will need to crimp, solder or use wire nuts because your dealing with a good amount of power. To power the bulb you either need a big 8+ amp 12v supply or use an old PC power supply. If your using a PC supply you will need to manually activate it or hot wire it.

Wiring Some More

Then youll need to use a little bit of thin wire to hold the bulb exactly where you want it to get the best projection. And you'll also need to run the projectors fan to keep the bulb cool.

Optional: You may also want to reset the bulbs timer. The one in this projector counts down from 2000 hours, but is not necessary to operate the projector.

Lights, Projector, ACTION!

Close the lid and fire up the power supply. I can get an eight to teen foot screen using this bulb. Add a medium to large stereo system in the front or back of the room for the perfect theater experience. Invite your friends and family to the Movies. Pop popcorn, have some drinks and turn on one of your favorites.

I chose this image to show how light and dark areas will show up with the projector mod. This image displays very well on screen, however is VERY hard to take with a digital camera.
