The bulb warning light came on and sure enough, one of the headlights (low beam) was out.  I contemplated the SilverStar bulbs that would give a blue tint to the lights but instead saved myself some change and got a basic replacement lamp, the GE H7-55 bulb for less than half the cost.  If I had gone for the SilverStars, it would have cost me nearly $100 because I would have had to change out all four bulbs.  Not on this rainy night!

Done and over for a fraction of that!  I put a new spare in the console for later...
