I'm replacing the 4v LEDs in my headlights with 12v. They aren't wired in a series but they do have this black box connected between the wires. Since they aren't wired in a series then that small black box must be reducing the voltage right?

https://www.cobaltss.net/forums/show...ange+color+ledI've used this post which has helped but mire LEDs are already wired like the second picture yet the new 12v LEDs won't work. I'm guessing that black box before the LEDs reduces voltage but I would like to know first before I remove it.

Well II could only wait for about 5 minutes and then I tried and removed the box from the LEDs. Now I have 3 12v high power LEDs instead of 4v.

I'll post some night pics tonight.

 

post pics. i wanna see

 

I took the pics in the daytime but in the shade. They are brighter than before and whiter.

 

you changed out your halo's too?

 

Yeah, I did that a while back.

Did you keep the stock diode or does these LEDs have diodes built in? I remember the many times I replaced my halo LEDs I connected a LED to a battery charger which is 12v to test and it blew, duh no diode...Just curious as to how you wired yours.

 

On the single LEDs or the LED halos. With the halos I kept the original resistor box so they wouldn't be too bright and the single LEDs have built in resistors.

 

Where did you get your led Halos?

 

Ebay 90mm and 100mm

 

Those look good! I have 3rd gen projectors and I am having a hard time modifying them for HID's.

 

I finally gave up on the Halo LEDs...there junk, and I was asking about the single's that you bought and thanks.

I had to modify my 1st gens, had to dremel out a small slot for them to fit.

i hate reviving an old thread. but how did you dremel out to fit hids? im terrible at figuring out why my hids suck. the bulb goes in perfectly. but the light output is terrible, any tips?
