Are the 9011 hi-beam HIR bulbs designed for continuous use (ie as low beam bulbs)?

There is no reason that the 9011 HIR can't be used continuously, as high beams are designed to be used that way. They do have a shorter rated life, 230 hours (they used to be 350) vs. 1000 for the 9012, but that is still far higher than overwatt bulbs. Also, if you look at an H1 bulb, which is used for many auto headlamps applications (the LX 470 low beams for example), it is rated at 350 hours for the standard output 55 watt bulb and 150 for the 100 watt overwatt bulb.
So in short, they can be used and the life expectancy would not be out of line of other lamps used in low beams.
