OEM Fog Lights.....wattage?

Anyone know what the wattage is for stock OEM foglights? These are on a 2000 Cherokee Sport. One is burned out, the other is cracked and I want to replace them with something aftermarket. I don't want to exceed the existing wattage of the OEM lights so I can safely use the existing switch/wiring.

A set of Hella 450's will pretty well fit in the stock location. They are 55w. This is what they will look like. I have them on my 98, the 550's will also work but they are bigger and I tended to bury them into dirt banks, hence the 450's...

Pilot sells a set of lights that are identical in size to OEM.
They are 55 watts and run $30 at Autozone.
Mine worked fine and I never had any issues with them besides a broken lens here and there.
