The rear brake/tail on the 05-06 hatchback is different then the sedan/wagon and is the 3057k according to my manual (please correct the listing).
That will make it a 27/7 watt instead of 27/8. That said, 3057, 3157 and 3357 are all interchangeable, and you can upgrade both to 3357, which is 29/8 watt.
The small wattage can't harm the casing or the wires, but the brake light output will be 25% more. This is one usefull upgrade IMHO.
