DSP: low pass filter

I need a simple (doesn't have to be really accurate) filter to cut all
high frequencies (say > 120 hz) from a stream of samples. This way I
want the peakmeter to react only on the bass tones.
I already have dynamic backlight dimming linked to the peakmeter value,
but it flashes at high tones too now...
Can anybody help me out?
