I agree on the mounting clip issue. Be careful not to bend them excessively. The spring clips I've dealt with do have a finite life.
I think buying the entire assembly is a better option than just replacing the bulbs. We spent three days comparing LED 3157 "drop in replacement" bulbs and the stock 3157's. Finished the experiment by putting the stock 3157's back in.
It seemed to me that if the housing/reflector is designed for regular bulbs, it's very difficult to get an LED "drop in" to perform well in it.
