On Alibaba.com (amongst others) you can find LED units that produce over 2000 lumen ussing in excess of 20 Watt. Some have a metal housing that extends from both sides of the plug. Some even have an inbuilt ventilator.
Reliability of these figures or the LEDs themselves remains to be seen, might be shady
None of these can replace the low beam as they emit light from a rather large area, as they always do.
Get a HID set, a 2x35W set saves you 40W compared to halogen and produces 3 times as much light. Got to keep them well aligned as not to blind other road users. HIDs typically last 6000 to 8000 hours of usage, chances are you won't ever have to replace them.
You might replace the fogs with LEDs to use them as DRLs instead of running low beam by day. They need to have more oomph than the 3W units I tried.
Better still, buy a set of LED DRL strips. They project most of their light in a level plane so they are more noticeable for the same watts than the fog replacements. I would do that if I had to do it over, and might just anyway.
