03 Tahoe Headlight problems

[Ankster]

My 03 Tahoe left headlight works intermittently, it is on when I initially start driving then it goes of for a while then comes back on. I replaced the bulb but still have the same problem. I can sometimes tap the headlight and comes back on sometimes.

Thanks

Is it the headlight or the DRL? Maybe a burnt socket?

How to determine if it is the socket
