    Hi guys,

    I am trying to replace my H8 halogen bulbs on my DRLs with LED ones. At first I got some off ebay, but one of the drivers went bad and smoked one of the LEDs. Also, they weren't bright enough, so I decided to go for a DIY.

    The design is similar to this:

    So, on each bulb there are 2 LEDs, opposite to each other, currently they are on series.

    Initially, my plan was to use the Luxeon rebels (http://www.luxeonstar.com/Cool-White-Lambertian-Rebel-220-lm-p/lxml-pwc1-0120.htm), but then I found out that XM-Ls are much brighter at lower voltage at 700ma.

    The cut where the LEDs are positioned on the aluminum are approx 10x15 mm.

    What would you suggest for LEDs and a driver? The H8 standard is 12v, 35W, but since we are talking car power, it fluctuates up to 14.5 when charging. Keep in mind that I am a newbie, so please use simple words [​IMG]

    I am thinking of getting four XML T6, two in series for each bulb. I just need a driver that can run 2 in series, and that will prevent getting an error about my lights on the dashboard.

    A dirver I found is:

    Thanks in advance.
