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. <b>Do the headlamp bulbs loose the quality of light output deteriorate over time and would new bulbs help seeing the road better? </b> 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.
