there's many ways, but it's a good way to kill your bulbs in a hurry. the glass isn't meant to be heated that hot, it's called a "pass" flash, it's designed to be used for less than 1 second at a time, use of longer than that will SIGNIFICANTLY reduce the life of the bulb, I would imagine that if you were to use that all the time, you're probably going to reduce it by something like 95%, which means that for every second you hold that on, you will take 20 seconds off the life of the bulb. This damage will be exponential for longer durations, so at 4 seconds, it's going to be something like 10 minutes of use gone for every second on... make sense? basically, there's a reason they don't just put that as your highbeam.
if you aren't putting out enough light, you might want to think about a) getting your eyes checked, b) making sure your headlight lenses are perfectly clear, if they are yellowed out, that will cause a huge decrease in light output, or c) putting on some driving lights...
