Nice job. Not sure if I would tackle it. Not as go for it as I used to be. Great post though.

Halos are not really a case of you get what you pay for. install yes, product NO. Multi color rings have led drivers on the back of them and when said drivers go bad sections go out. HID heat will turn white leds blue when hot. Xtremeledsonline.com offers an alternative. External drivers!. and for many makes and model cars. If a section of LEDs goes out you can be sure its a driver issue and with the external driver kits they offer all you replace is a affordable driver module and not re open your headlights or remove them from the car. just plug in a new driver and done. I have had mine for 2 years with zero issues and installed several since. they also offer pre installed in after market headlights and drl/fogs. Best design i have ever used and cheaper then others. 92% of led failure is due to drivers. it pays to know

Halo LEDs

Good info, but I'm confused. Is that the little black squares with tiny numbers on them on the back that your calling drivers? I thought that those were "diodes" a electrical check valve in a sense. My halo LEDs that I am selling don't have a driver that I am aware of. The led its self uses 12volt unlike others that use a small power inverter or transformer to lover the power from 12volts to 3-4volts.

There is the control box "maybe that has the drivers in it?" I thought it was to split the power from one 12 volt line to four 12 volt lines, to control the led colors, flash mode and dimming feature and to house the Epistar microchip? Just not sure what you mean drivers?

I know my HIDs have a small transformer that ups the 12 volts to 35 volts. That is more of what I think about when you say driver, but on my LED Halos I sell I think the battery itself would be considered the driver.

A LED driver is an electrical device that regulates the power to an LED or string(s) of LEDs. What makes a driver different from conventional power supplies, is that an LED driver responds to the ever-changing needs of the LED, or circuit of LEDs, by supplying a constant amount of power to the LED, as its electrical properties change with temperature.
Think of an LED driver as ‘Cruise Control’ (like in a car) for the LED, and the temperature changes of the LED are the hills and valleys it is ‘driving’ over. The power level (or ‘Speed’) of the LED is maintained constant by the driver as the electrical properties change (amount of ‘gas’ or power needed) throughout the temperature increases and decreases (or ‘hills and valleys’) seen by the LED(s). Without the proper driver, the LED may become too hot (driving too fast) and become unstable (out of control), causing poor performance (engine problems) or complete failure (crash!)​
