GLSL shader - array of uniform const

I need to pass multiple lights to my shader.

I coded my shader in CG/HLSL and it works fine. Now I need to convert it to GLSL and I don't know how to make an array of conts.

Here how it looks in HLSL (2 lights for an example, really there are more of them):

 Properties {
     _Light_0 ("Light", Vector) = (0.5, 0.5, 50, 0)
     _Light_1 ("Light 1", Vector) = (0.5, 0.5, 50, 0)
     ...
 }
 ...
 
 CGPROGRAM
     half4 _Light_0; 
     half4 _Light_1;
     ...
     static half4 light_params[2] = { _Light_0, _Light_1 };
     

And then I'm accessing light's parameters by something like: light_params[n].

So, how it should look like in GLSL ?

I've tried the following code but it doesn't work:

 uniform lowp vec4 _Light_0;    
 uniform lowp vec4 _Light_1;

 const vec4 light_params[2] = vec4[2](_Light_0, _Light_1);
