I sure hope nobody held their breath for this how-to. JoeWorksTooHard (JOE), helped me greatly in this process. If you have any questions ask him, or myself. But here it is:

1.) Own a Cobalt
2.) Have the projector halo headlights
3.) Have most of these materials:


They are: Soldering Gun/Iron, Rosin (to Solder with), 10 MM Ratchet (to take out the headlights), Needle Nose Pliers (to pull out the led's). 3MM/T1 LED's. They are either called 3MM or T1. There is 2 LED's per halo. In this case, I put WHITE LED's in there. You could also use a De-Solderer if you have one.
4.) Pop hood. Remove headlights using 10 MM Ratchet. Take the headlight out.
5.) Use a screwdriver to un-pop the rubber grommet to which halo you are replacing.


6.) Get your Needle Nose Pliers and grab onto that rubber grommet inside, and pull up


7.) You should be able to wiggle it out.



8.) Unhook those spade connectors, flatten it out and remove the rubber grommet. It looks like this


9.) Heat up that soldering iron/gun and put it on there to liquify that rosin on both sides.


10.) You will have to cut the legs on the LED that you are putting in there. Here is approximately how long the legs should be


11.) Here is what the LED's are supposed to look like on it


12.) Solder those back on and replace the rubber grommet


Here is what it should look like with WHITE LED's:


Here is what it should look like with BLUE LED's:


Let me know if you have any questions. You could also talk to JoeWorksTooHard. Hope everybody has fun with this, and I hope to see some different colors!!!

 

Approved. It's "grommet" by the way, not garment. That's something you wear.

 

You're the shiznizzle JPizzle. Nicely done. Blue looks sick.

 

will have full blue ones as soon as i get my leds from mkulrey

 

Nice Write Up.

 

jpizzle forgot to ask man. what was the Ma on those leds???? Ma would mean miliamps

 

damn...that looked easier than i was thinkin it would be. good write up guys!

 

Looks good, i need some leds!

nice

 

i am guess those are the same as what i ordered from you????

 

Nice write up. I'll be contacting you(Mkulrey) soon for some LEDs.

 

Thank you so much for this how to!

 

can you change the halo's to red??? I would get them but they only come in blue and a have a red SS. so thats not going to look all that good

 

Red halos would look nice but your gonna get pulled over as soon as you get off of your driveway.

 

Nice write-up JP. Lookin' good!

 

very nice man

 

tag this for later. nice rite up

 

quick question, how did you unhook the halo led from the spade connectors.. did you take the heatwrap tape off? i could never get those connectors off so i just soldered the new ones in with them connected.. this is like the 3rd time i had to solder new ones in because they keep burning out on me.

 

i have a quick question i actually had the chance of watching oneof the l.e.d.'s go out. it was flashing and i was like wtf then it just went out. do you think this a loose wire or connection or did it burn out?

 

Some tips for doing this.....

Make sure you keep positive to positive and negative to negative. When you buy the LEDs the longer one is positive, shorter prong is ground. The red resistor is positive on this model and you can see below on the breadboard that it states positive. The other side is yellow and says negative. Try not to cross them.

Prongs:
I broke a prong and had to solder it back on until I realized it was easier just to slip the halo lights in BACKWARDS. Slide the forked prongs in first, then guide the leds in the little hole last, then spread the prongs to help situate it in place.

If your leds keep going out you have a bad resistor. Replace it.

 

did all of my leds with UV 3mm LEDs....they are fine for the angel eyes but the halos are gimped. Probably because the MCD is only 3000 and seems that ultra violet is naturally ALOT lower than others. Cant wait til my 5mm 7k UV leds arrive. Looks like they could fit (bit snug) ill post when i get them.

Ill post a pic later but seems completely dark at night my camera blows. Only good during the end of a sunset at most



see?

 

^^where do you get these leds. i'd be interested but like stated above would like to get some red leds.

 

theres someone on the site that sells the LED's (all kinds) i forget his exact screen name but hes selling the rear koni struts (in the FS section) and it says the LED expert on either his sig or under his name

lol there you go... i forget sometimes
