Place light edge in car roof

[brigada_spanish 11]

I want to put on the roof of a vehicle a light edge, with "Land_runway_edgelight_blue_F" object with this option works correctly.

_pirulo = createVehicle ["Land_runway_edgelight_blue_F", getpos _car,[], 0, ""];
_pirulo Attachto [_car, [-0.60,-0.65, 0.25]];

But the problem is, that part of the object is inside the car.

I have tried to edit the image layer Alpha1 "runway_edgelight_co.paa" to remove the concrete, But it has not works as follows.

_pirulo = createVehicle ["Land_runway_edgelight_blue_F", getpos _car,[], 0, ""];
_pirulo setObjectTexture [0,"mi_mod\data\runway_edgelight_co.paa"];
_pirulo Attachto [_car, [-0.60,-0.65, 0.25]];

I've tried "setObjectTextureGlobal" and still not working.

Can someone help me to solve the problem.

Greetings.-
