Hello! I'm new to this forum and truly pleased to have finally found a group of people who understand the difference between color temperature and lumen output, who discuss the interaction of the eye and the light on the road and who can tell a beam pattern from a hole in the ground. I hope I can actually contribute, at some point, though right now I'm afraid I will be a consumer of information.
My personal Hell? Trying to see down the road using the standard lighting setup on our 2015 Mercedes GLK250. For whatever reason, Merc decided to use H7/reflector lows and H15 highs, coupled with a "string of pearls" DRL occupying the place where fog lamps lived on earlier versions of the trucklet. From what I've read here, uprated H7 lows are the obvious starting place. I've replaced the stock with Narva +50 that I had lying around but will likely go to the Osram Rally 65W. H15 highs are a giant pain: only no-name Chinese units and horrid HID and LED "conversions", none of which I would ever use. The only other alternative I've found is an Osram "Cool Blue Intense" "+20" bulb, sourced from the big-river-sounding-online place's .de site. I've installed them but the difference is minor; better than nothing but probably not worth cost plus shipping, in hindsight..
Making matters worse, I live in a community with very twisty, unlit streets; standard beam pattern does not give nearly enough light to see pedestrians around low-speed bends. My old VW had cornering lights. Merc puts cornering H7s on GLKs with bi-xenons which I don't have. Since they also don't offer front fogs with Halogens, I can't even turn these on. So, I'm debating adding aftermarket fogs of some kind but really don't know where to start.
