I recently changed my low beams and after reinstalling the head lamps, both side markers are now not operating...additionally, one of the positioning lights also is not operational now. I cant identify a fuse for these lights and I dont think its a coincidence that both front side markers went out while I was removing the headlamps. Any ideas?....I have a 2012 elantra touring

Thanks in advance

 

If you didn't pinch any wires in the process it is unlikely a fuse would blow.
It might be a good move to go through the steps you did previously and recheck your work. Remove everything as done earlier and look for a loose or disconnected wire. Sometimes a ground wire gets loose or disconnected.

 

What bulb is this....the one below the high beam in the same housing

 

That's just the "city light". It's not really required in the US.

I can't find any info on the bulb though....one is out

 

It should be the same as the side marker bulb

 

Its actually a tad shorter and rounder than the side marker

 

Ok so I call the dealership and they have no idea what this bulb is. Any assistance would be appreciated.....again it is in the same housing as the high beam....it looks a lot like the side marker bulb but it is shorter and wider around. Also....I need to know how to get to the rear side marker to change it....doesn't seem accessible from underneath
