I tried them. The bases didn't fit, but they looked pretty cool. They don't really fit too well in the housings either, one of the arms will be slightly bent.
I would have still ran it had the bases not at all been 3157 spec.
Didn't get any pictures because of the bases. They wouldn't click in, they'd just launch out of the base from the spring force trying to put them in the wiring sockets. Then they'd end up getting lost in the housing. So you couldn't get them to actually work, when you tried to twist the base in they'd just launch out of it and get lost.
The arms all fit, but one of the arms would bend a little. Not sure if you'd notice it when they were on or not.
