Left headlight not burnt out but doesn't light

When I turn on my flip up lights the left one will light up for about 2 seconds and then flicker and turn off, I have beamer HID 6000ks. I have searched for some answers and found a write up which I followed the steps carefully but still no results but it did make one tiny difference. Before I did the fix the whole left side wouldn’t light up including the white light which is on the front bumper but after I did the fix it turned on but my left headlight will still flicker and die.

Here’s the write up I followed.

smack the headlight

also if you used taps incorrectly or didn’t ground properly you’ll get bad contact aka flickery headlight.
