The tail light on my car burned out recently. When I opened up my trunk, I realized I had no idea how to access the light bulb. It was not obvious or simple. Still, it was only a light bulb. Then I went to buy the light bulb that I had no idea how to install. The same Sylvania light varied from $3 at Walmart to nearly seven dollars at Napa. I was shocked at how this could be so. The same part number and everything. And, you can get a package for two bulbs for about 30 cents more than a package with one bulb. So, bulb in hand, I re-visited my trunk after finding this nifty car repair web site. With my new found knowledge, I realized that the evil geniuses at Ford hadn't made it as tough as I feared, it was just in knowing where to look. I changed the light bulb in three minutes. Yay!
