I was driving last night (out of town) and have trouble seeing at night. The headlights on my car were so dim (original light bulbs, about 15 years old). No way would I want to go through that again. So today, I went ahead and bought a new pair of headlights.
Amazon.com: Sylvania 9007 XV BP TWIN XtraVision Halogen Headlight - Pack of 2: Automotive
Got the lights at Autozone. Also, bought the bulb grease (didn't know they had such a thing) in the little packet. My car doesn't make it easy to change the bulb. Didn't have any tools so didn't remove the light casing. Instead, fiddled around and around with it til finally changed. The bulbs are a lot brighter. In full sun, I can still see the hightlights on where no way before could I see them on.
I knew to wear gloves to avoid putting hand oil on the glass of the bulb.
But in my fiddling around to get the bulb in place, I may have got a little bulb grease on a bulb. (I did go ahead and wipe the bulb with a napkin) Would that be just a bad as had oil? Hopefully, that won't shorten the light bulb's lifespan.
