Hi from Minnesota. Today I swapped out the factory halogen bulb in the porch light fixture with an LED. I've attached photos showing the original bulb, a side-by-side view of the halogen and LED, the installed LED bulb, and a snap of the part number.
Once you get the cover off it's a very easy install. Pull out the halogen and then insert the LED. The heat shield/reflector does need to be either removed or bent upwards. I chose the latter in the event that I go back to the halogen. Not sure why I'd need to do this but just in case I decided not to remove it.
If you look at the installed LED photo you can see the how it looks.
