So you read the DIY for a demon eyes mod with the stock projectors...

http://www.ft86club.com/forums/showthread.php?t=25740

BUT, what if your not running stock projectors and went, or are going to, retrofit.. Well for the most part if you can do a retrofit, you probably don't need a DIY for demon eyes, but HARDROCK, got me thinking about running the painted plates and LEDs..

I don't run autozone LEDs or anything like that, as a electronics tech I make my own circuits and stuff.. So a quick trip down to radio shack and picked up some parts

I already had the big 10mm LEDs for my sons science fair project, but they wasn't what I wanted for this project.. Most should k ow that LED stands for light emitting diode.. And they have a very narrow angle of light dispersal.. Head on they are bright, the more you move off center the less the emit.. Hence why the technology is expensive for use in headlight and other auto lighting applications.

I bought a pair of 5mm LEDs for this mod. Now I. The led world size doesn't mean much, the 10mm has a intensity level of 400 mcd and a viewing angle of 16 degrees. The 5mm has a intensity level of 3000 mcd, so it is much much brighter, but in these perticular LEDs the viewing angle drops to 12 degrees. That's all they had or I would've went with a border viewing angle as I want to fill the housing with as much red light as possible.

Now you can't just hook up these LEDs to a 12 volt source both have a max volt of 2.4 and 20 mA and hooking them up to a 12 volt source, well they won't last but a second, so you need resistors, in my case I went with 1k ohm 1/4 watt resistor.. I could've used 500 ohm but they didn't have them 1k will be just fine.

I also bought a switch and fuse holder and fuses

I like to do a lot of testing, no reason to hook everything up then find out it didn't work, so I picked up this cheap pilot brand cig. Lighter acc output to test everything, also used a lith. AA batt to test on my bench

All good builds need good tools

Just a quick wire up to make sure everything works

I hooked up both LEDs so you can see the difference

It might look like they are both the same brightness, but they are not

As you can see the 5mm is much brighter

So I drilled a small 5mm hole in the bottom center of the light housing

My drill bit walked some on me... I should've used a smaller sharper bit then I did

I used a good RTV adhesive just to make sure it doesn't fall out

And just mocking things up

And just a teaser

Now I wanted this subtle, I wanted this to be able to stay on all night if I choose because LEDs hardly use any power, and I don't want it to look like I left red headlight on

I'll finish the rest tomorrow, I got everything lined up and aimed properly. Just need to wire up a switch and everything
