As usual at this time of year, the number of 'one eyed monsters' is clear for all to see : people who have one headlight out and thus try driving with the remaining headlight on full beam to try to compensate. It's irresponsible, it's not very courteous to other drivers, and it costs about $10 and 10 minutes of your time to fix. So go and get a replacement bulb - in fact get two and replace both at the same time - and swap out your headlight bulbs. Just make sure not to touch the glass part of the bulb or you'll very quickly have it blow again.
Caveat: if you have HID lights and one of those suckers is out, make sure to remortgage the house before visiting your dealership to get it replaced.
