Headlights on the 5 were still functional, but seemed to be pretty dim at 67,000 miles. Installed Sylvania Xtravision H11s. Stupid easy installation, feel bad for the 2006-2010 folks for how bad their installation looks. On the 2012-2015 you just pop the hood, unplug the bulb, twist, remove, replace, replug, close the hood. Took about ten minutes total, would have been faster if I hadn't done it at dusk and had a screwdriver handy for depressing the tab to unplug the electrical line. So far the new bulbs are definitely brighter than the old bulbs (the OEM ones are Phillips H11 Long Life, by the way) were at the end. Not bad for $32 from O'Reilly.
