my passenger side headlight is not as bright as my driver side headlight on my cavalier. does anyone know why and how i can fix it?

...... now please take this seriously as it is a trouble shoot to figure out if its just the bulb or the lens or the wiring (which i doubt ..... my bet is the bulb)

Switch your bulbs out ..... left on right and right on left ..... let us kno if its the same ...
if it is then you narrow'd the answer down to 2 out of 3
when yoru lights are off .... is there a discolouration of the right side lens or chroming on the inside compared to the left side ???
if these 2 dont work .... next step is to get a real voltage meter and test the sockets to see if they are both getting the same amount of voltage ....(not sure whats the Exact numbers but im sure tsome gusy in here do )
if they are not u need to start tracing it back from the socket to the relay .... then to the fuse ......then to the switch itself .....

is it possible to take a pic and post it here for us to see ?

so what happened was it the bulb?
