I have a 99SL2 Saturn with fog light. I have replaced the fog light bulbs when they burned out, but never the low beam headlamps. Do the headlamp bulbs loose the quality of light output deteriorate over time and would new bulbs help seeing the road better? My main problem is when it rains. Even with headlights and fog lights on I have a hard time seeing the lines on the road. I use my fogs always so I have no time seeing when the weather conditions are good. I had a Sentra that had poor lighting, so I replaced the headlamp bulbs with Extra Vision ones. They made a noticeable difference, but would last less then a year. I don't want to use a bulb that has a short life, so my understanding an OEM bulb would be better for my needs. Thanks in advance.
