Thanks for the additional tech details.
Yes, my idea was to share the housing, although I don't think I'm that skilled and wouldn't want to create interference, neither mechanical nor electronic. Since the circuit board is the full width, I don't know if an inch of depth is enough.
Another question since you seem to have good knowledge of car electrics. Since I have a hybrid, do you think installing fog lights which bypass the BCM, just simply wired to battery, ground and switch, would negatively (npi) effect the electrical system in general? People have mixed opinions as to whether or not to mess with a hybrid system but as I see it, it does just use a regular 12v battery for regular electrics and the Lithium Ion to drive the electric motor for the drive wheels.
And to Tiger-Heli, yes the SEL model has fogs standard so the parts are available.
