intermittent headlight issue

Passenger side headlight is no longer working. Had issues that self resolved about a week ago. I didn't do the install and cant seem to find a brand name? Anybody recognize these lights? All other lights within the housing still work except the headlight. Just a bulb replacement?

 

Look like 'no see 'um's' to me.

 

Here’s some pictures of the headlight

 

Dunno what they are, as I'm not hip on all that glam stuff.

However, you could

1) test the light socket that's out with a DVM to be sure that it's hot when it should be

2) put the DS bulb in the PS socket and see if it works. If yes, a bulb seems likely.

 

Try swapping the ballast/igniters from the working side to the other. If that doesn't fix it then swap the bulb.
