Will my car fail its MoT because a door mirror indicator doesn't work?

My 2010 Hyundai ix35 has indicators in the door mirrors. One has failed. Does this mean that the car will fail its next MoT?

Is the placement of the indicators on new Hyundai cars flawed?

Can I ask your opinion please on the indicators of the latest Hyundai cars? It seems to me that there is a serious design flaw on these new cars. The indicators are set right at the bottom of the rear...

Is there a minimum size for LED indicators?

Is there a minimum dimension standard for LED lights on new cars? Twice now I have not spotted a turn signal in daylight because the turn light was so small.

Vauxhall Zafira (2005 - 2014)

Compact yet can house seven people. Rearmost seats fold into floor. More versatile mid-row seating than previous model. Excellent diesel auto.
