There is a device much like a relay and that looks similar to a relay for the low beam bulbs in the under hood fuse block for the low beams. This is common for failing. There is another one for the engine fan. Swap these to see if the lights come on. The numbers on the top are 15016745. That is also the part number to order if that if the lights come on.
