85 S-10 Blazer Problems

I Have two problems with my blazer. One My left head light goes out occasionally. Two My clutch makes a clicking/ rattleing sound when the peddle is pressed. can anyone help me with this?

check the wiring and the plug socket it's probably coroded. clutch noise could be a few things most likely bad release bearing. does the pedal bounce/pulsate when light pressure is applied? if it does you might have a warped flywheel/ warped clutch disk/ bad pressureplate diaphram
