When I first got my Prius, I noticed that the fog lights were cracked and had the repair priced it at the dealer. Then I started searching on the forums and read alot about how common this seemed to be. There was no shortage of different opinions and speculation about causes. I decided to believe that the bulb gets too hot and will crack under the extreme heat. Regardless of what I believed, however, I still needed them replaced. So, I purchased a set on Amazon, and I also purchased a set of Laminx "shields" to put over them. The install wasn't that hard to go through step by step (thank you forum!), but accessing without a lift was comical. I'm no skinny minny and my head and shoulders wedged at just the correct angle under my car to view and then to reach in to remove/plug in was an adventure. Price for bulbs was a total of about $80.00. Mechanic was going to charge $150 for labor, a deal in itself, but I decided to at least give it a go. 8 months later, the fog lights are intact, no cracks. It's the little things.
