Weird electrical issue with Headlight

[Subru]

One of my headlights does not work and long story short, the wire connecting to the bulb is short circuiting (dunno exactly where its shorting out) , how should I go about fixing this?

Its the large connector/wire you can see that plugs into the top bulb that we tested and it seems to be shorting.

What makes you think it's shorting?

I'm also fairly sure that wire is only your high-beams.

My brother knows a bit of electric stuff and he says its shorting and the wires on the other light are not.

When I turn on my lights fully, the left headlight has the small light and the big light working but the right headlight has only the small light working where the big light should turn on as well... I got pulled up be a police coz my light was not working  

I might be wrong, ill take a picture and post it.

depends how he diagnosed it i guess. if he done something like a continuity test from end to end on the wire then probably a fairly safe bet the wire is at fault. i would prefer to rule out connectors/switches/relays first before ripping out the wiring as from first glance it looks like could be ab it of a mission . anyway if you can trace that wire, try looking for obvious kinks as first step, there are many inbetween options to further get in to which section of the cable is at fault but will test your patience for sure

Are you sure it is not the bulb? Swap the bulbs between the sides to verify if it is the bulb or the power feed/ground.

You could try wiglying the wires to see if you can get the light to dip in and out indicating a poor ground or connection somewhere. Then if it is a wiring issue then trace the wiring and check for breaks, loose connections or poor grounds.

 

Remember if they are the HIDs they use a very high voltage so be sure key is off and maybe disconnect the battery if you are unsure before removing bulbs.

tested 3 different bulbs, no luck, wiggled the wiring a bit, lights dont dip but I do notice that when I turn the lights on, the lights flash once for some reason (as if the lights turn on real bright then go to normal but it looks like a quick flash).

Do both lights come on at first? Then one disappears?

idk actually, dont think so but Ill take a look soon

It could also be that the HID ballast is failing. Not really sure how to test a ballast but I'm sure google will tell you.

Sorry to hijack but I have the opposite issue. Sometimes only one will work then both will start working??

The reason I ask is because in a car it's not really a thing that happens... if it "shorts" then it blows your headlight fuse. EDIT: These, I believe, have an independent fuse and relay for each headlight, checked those?

 

Just intrigued to know the diagnostic process that went into concluding that it's shorting.
