Hi Folks, I searched a lot and could not find an answer or a hint on what is going on with my MCS coupe '12 headlights.

The headlight Low Beam works fine on both sides and when I pull the switch to turn on the High Beam temporarily, it actually works fine but when I push the switch to turn on the High Beam permanently then it does not work and other light also turn off even though the blue light indicator on the dash shows it is on

I would really appreciate any help or input on what to do or where to look for the problem. Thanks

 

Did you buy the car used? Is so, perhaps previous owner installed some kind of aftermarket headlights without the ability to hold high beam. After looking into headlight upgrades for my 2011 with halogens, I see a lot that say "flash-to-pass only, unable to hold high beam" or something similar. Like the Spec-D lights. If still stock, no idea, sorry.

 

Yeah...check for aftermarket headlights....many are low beam only...with a flash to pass...kinda crappy...but for a certain crowd that wants to look like they have $$$ hid's....they like them...

 

wow.. yes I bought the used car at autonation. I have to check my headlights.

so can you let me know that I have to check my headlight bulb? or headlight assembly?

Thank you for your help!!

 

Thank you so much. I have to check that.

 

Dear Amitayuth , I hope you can help me out ? I got exact the same problem as you .. when I bought the car there where mini original HD bi installed ,
now high beam on hold is not working , when I push al lights go out... when I pull high beams are working.
I bought brand new h4 units but the problem would be the same.. I hope you've got the right answer ?
thanks so far !!
