Night photography

I just started night photography. I owe a Rebel 350D with Manfroto tripod and I used a Canon EF 50mm 1.8 lens. I would like to know what kind of filter can I used to avoid the glare of street light on pictures.

Thanks for the cue

A lens hood.

I cannot see the exif-data. Can you make this available (in particular aperture).

heres some insperation for you http://www.arinahnell.​com/

No. But it will cut flare from side lights.
Leave the UV, or any other filter off. Clean the lens. Make sure that your focus is DEAD NUTS ON! Go out at night & take a pic at each f-stop & see what they look like on your computer. There should be a combination of f-stop/shutter speed that will reduce the flare.
