Hi guys,
regarding the heat: Yes, they do heat up. But so do the original bulbs.
For the poor people whose bulb fell into the housing: Yup, happened to me before. However, since I didn't want to take off the front bumper etc., I took a metal coat hanger, bent it in the shape required to fit inside the housing through the socket and put some sticky double-sided tape on the tip.
Took me around 5 minutes of extreme patience, but was able to fish it out eventually.
Maybe that also works out for you.
Cheers,
Len
