I think just tossing an HID kit into the stock headlights sucks because they have the worse beam pattern I've ever seen. HIDs would only enhance this.

 

I've had my Denji halo projectors for almost two years now and never had any of the LEDs go out on me.
Then again the TYC set I had before that sucked(light output) and one of the LEDs flickered occasionally even though it was wired directly to the others...

there are a couple of pics where you an see 'em over here.

 

yeah, I've never had a problem with my halos. After 2 years, the led's never burnt out or anything. With the supplied wiring harness, you can have all 4 beams on at once which makes for some bright ass high beams.

 

HID's in stock headlights are unsafe and blind the shit out of everyone else on the road.

Stock beam pattern with a halogen bulb is fine.

 

I even felt the stock beam pattern with a halogen bulb was pretty bad. That's just me though.

 

How would one go about replacing the LED in the halos? Is it hard? I got my halos off ebay for 130 shipped. I guess that might be why the one of the halos burnt out. The overall fitment was actually really good. Also im interested in have all 4 lights on at the same time. How would i have to go about wiring the headlights for this.?

 

replacing the LEDs isn't difficult if you know how to get the headlight apart. (search headlight baking procedure)
then it's a simple as replacing the stock LEDs with ones of your choice. BTW matching colors is more difficult than you think, LEDs are seldom the same color even if they are supposed to be.

projectors come with a harness setup that makes the low beam on with high beam operation work. If you don't have the harness you will have to make one.
It takes four relays, a some 12gauge power wire, some 20gauge wire and two 1Amp diodes. (all generic parts) Let me know if you want me to draw a schematic of it for you.

 

Here is a pic from mine. The light output does suck from the projectors. I bought catz bulbs for the highbeams and aimed them down for normal driving. Probably going to retrofit the projectors this summer b/c I still like the way that the 1 piece looks with the hood.

 

Retrofit is the way to go, these halo projectors make retrofitting easier.
The LED's aren't plug and play, you'd have to do alot of chopping.

 

i figured i had to take the headlights apart. i think i'll leave them be untill all the LED's burn out.. no sense taking it apart to fix just one. I'll bear with it.
