Part needed:
A length of FlickStick = Clear Acrylic/Plastic Rod used for opening and closing window blinds/curtains etc. (Found at Spotlight or any Curtain retailer).
Diameter approx. 8mm. Length varies from approx. 60cm to 125cm.
Cost: for a 100cm APPROX. $4.99.
Ooooooh, now I have to live on strict budget again.

A Dremel.

2 x WHITE or BLUE, 5mm, LEDs. From 2 - 8000mcd (for each ring)
1 x Resistors 220 - 420 ohms. Depending on how strong you want the light to be.

1 x Oven.

Usual tools and some.

1- Cutting the correct length.

We need to create a circular ring out of the rod.
In order to determine the circumference of the circle, measure the diameter of your either Hi or Lo beam reflector. That is if you want to have Halo Rings around both of the reflectors.
In this case it comes out to be 10cm (or 5cm radius).
Using the circular formula (C=2πr, where π=3.14), cut the rod about 32cm long.

If math is not your thing.
Take a string or shoe lace, lay it carefully around the edge of the location you want to mount the Angel Eye.
Mark the ends and use the bit you marked to cut the lengt you need.


2- let’s get the rod to light up.

In order to make the ring to lights up like the true 'Angel Eye', you need to refract the light as it goes through the rod by making multiple cuts along the rod.

As you see from the picture there is not much light being reflected.

Use a Dremel and cut groves in the rod.
Each cut/groove allows the light to 'escape' the ring. Each cut should be about 2~3mm apart and 1mm deep. This will make your ring look like a continuous band of light.

DO NOT CUT ALL THE WAY THROUGH THE RING.

To get the cuts look perfect, use masking tape and draw a line every 2-3mm. Stick the masking tape to the rod and cut along each line to a depth of 1mm.

Don't make the cuts too close to one another.

You only need to make the cuts along one sided of the rod.

Make sure that the cuts are evenly space out.

It will take about a few minute to do the cuts using a Dremel.

If you don't have a Dremel, you can use a small saw, but then will take you a bit longer to do the job.

http://i120.photobucket.com/albums/o169/paulumbo/AngelEyes05.jpg

Here is few cuts.

http://i120.photobucket.com/albums/o169/paulumbo/AngelEyes06.jpg

Use a saw blade and even out the cuts so they are all starting and ending at the same place of the rod.
If you have access to an air compressor, blow the shaving off the rod. If not a brush would do.
To see the final effect these cuts have, turn the rod upside down, so the cuts are on the bottom side of the rod.

http://i120.photobucket.com/albums/o169/paulumbo/AngelEyes07.jpg

Now you can see how the cuts refract the light and how the rod hides any imperfection in the cuts.(Remember this is only an example to show you how. I know the cuts are not exactly perfect….(.


3- Making a ring.

Now, find an aluminium can or a glass jar (let’s call it a Peanut Jar) that has about the same diameter as the ring you want to make.

Heat up the oven to 150°C. When the oven is 150°C, turn it off.
Place the rod on an aluminium tray and then leave it inside the oven for 10 minutes.
Put on a pair of oven mitts or gloves and take the rod out.
Hold the two ends of the now VERY bendable rod with your fingers and wrap the rod around the peanut jar lid and hold it for few seconds.

MAKING SURE THAT THE CUTS ARE EITHER FACING UP OR DOWN (not sideways towards or from the jar). In the above picture they are facing down.

The rod will harden within 30 seconds or so.

If you did not succeed to make a perfect circle, repeat putting the rod in the oven and warm it up etc….. one more time.

Now you should have a nice circle. With the cuts facing up or down.

There is your ring.

4- The LED

Attach the resistor to the positive terminal of LED bulb, which is the longer of the 2 terminal leg.

Attach a wire to the LED first, and then attached the resistor at the end of the wire on the positive terminal. This will give you flexibility because the resistor will be outside your headlight unit and you can change it if you have a need to do so later, like changing to a lower resistor to make your Angel Eye brighter.

5- Securing LED Bulbs Inside Angle Eye Rings
To secure the LED bulbs into the rings, drill a hole in both ends of the ring, 5mm wide and 5mm deep.

http://i120.photobucket.com/albums/o169/paulumbo/AngelEyes10.jpg

Parallel connect two LEDs for the both ends of the ring together.
After soldering a 25cm long wires to the positive and negative legs of the LED bulbs, wrap black electrical tape around or use some shrink wrap on the exposed part of the legs and the wires to keep them apart.
Attach the resistor to the end of the wire later on and connect the wire to the parking light.

Make sure you connect the correct wire to 12V+ and earth.

Next, insert the LEDs inside the holes of the ring, and either wrap black electrical tape around them or use a drop of Superglue to fix the LEDs to the holes you made in the end of the ring.

DO NOT paint the rod, specially in black.

The black paint will absorb the light and will make your angel ring look dim.

If you plan to wrap the black tape around the uncut/unused part of the ring, make sure you wrap some aluminium foil around them first before wrapping the black tape.
The aluminium foil will reflect the escaping light back into the ring, making the ring brighter.

This is how it looks with ONLY one LED.



6- Securing the Halo Ring to the reflector

Use either JB Weld or Super glue to glue the Angel Eye rings to the headlight housings trim or the reflector edge or if you got a bezel. i.e. a suitable place.
Apply only a very small amount of glue to the un-scratch/un-cut part of the ring. The inner black frame acts as a barrier and helps protect the Angel Eyes from the heat coming from the reflector housing.

MAKE SURE THAT THE CUTS ARE FACING DOWN or ARE AT THE BACKSIDE FACING THE TRIM/REFLECTOR EDGE etc., WHEN GLUING THE RING.

Before reassembling the headlight lens to it’s housing, test that everything works OK.
If everything is OK, reassemble your headlight lens to it’s housing.

Permanently connect the LED wires to 12V+ and earth of your Parking lights.

Enjoy your Angel Eyes.

Enjoy. This is a very easy mod to do!

That is a pretty cool write up though.

Nice write up, but did you do it yourself or just pull the write up from somewhere else? I think the Halos would fit better on RLinBatonRouge's headlights with the HID unit.

agreed - if/when i go w/ a projector conversion kit, these would be a sinch to tak on right inside the housing....

I pulled the write up off of www.hidplanet.com I was looking for a way to make some footwell lights for the RL and I used that write up to make them, just didn't bend the acrylic in a circle.

agreed - if/when i go w/ a projector conversion kit, these would be a sinch to tak on right inside the housing....
They do look really good w/a projector retro. I'll post up some pics of mine-I used TSX projectors which are one of the best out there right now. Oddly enough I don't have any pics of my car. If I ever open the lights back up, I thought about doing them as DRL's which is what they're used of ron BMW's 'cept they call 'em City Lights.

Yeah...I know it's a Honduh, but at least you know how they look. He does have a good write up too and some pics with them in different colors.
