flare collider bug

Hello! I have a problem with the lens flare of a light (spotlight: lens flare), I put the lights inside the car and the flashes are not seen because they are inside the collider (box collider) of the car, but when I move them outside the collider look perfectly, how could you make them look the same inside the collider ?. Thank you

You can set your car GameObject to be under ‘TransparentFX’ layer.
Doing so will make lens flare(-s) go through the object.
