replacing bulb?

[rfuree11]

i know this sounds dumb, but i bought my PIAA 520 smr's used and dont have a manual or anything for them. A bulb burned out in it today. i was just wondering how you would go about changing it? Do you just unscrew the two screws on the sides of it and the front pops off?
edit: also, what kind of bulbs are they?

Just loosen the screws on ea. side & pull the lense off the light body. There is a little nut thats sort of a pain to put back on if you screw it out too far. It takes an H-3 bulb. I really like PIAA 85/130 watt superwhite bulbs.

i just got some silverstars and the difference from the bulbs that were in there is amazing
